Ball migration – a common issue with ball bearing slides

Author: John Whittlesea, Technical support manager


24th Jun 2015


We recently received an interesting question from a company looking for drawer slides. Their worry concerned something they called ‘drawer creep’.

The problem mainly occurs when the drawer is repeatedly partly opened and not to the full extent of its travel.

When this happens often enough the ball cages (retainers) start to shift out of position and because the ball retainers form part of the slide’s stopping arrangement this causes the drawer to stop in the wrong place.

This generally means that the slide will stop short of its fully open position. Sometimes the slide will neither open nor close fully, but mostly it is the open position that is affected.

If the slide does stop in the wrong place then the only way to overcome this is by forcing the moving element to its fully open or closed position by pulling sharply on the slide or by slamming it. This should overcome the non rolling friction of the balls and force the slide back into the correct position.

We more commonly call this problem ‘ball migration’ and unfortunately this is a characteristic of all ball bearing slides, not just Accuride slides.

How to prevent ball migration

When drawer slides are repeatedly opened to their full extension, the balls and retainers will stay in their correct position within the tracks and the slides will continue to give perfect service.

If partial openings are common practice, then it would be good practice to occasionally cycle the moving element (normally a drawer) to its full extent. This will ensure that the balls and retainers are put back into their correct orientation as a stopping element of the slide design.

One thing that SEO consultants are constantly doing is future proofing clients’ websites and web strategies.

SEO practices change quickly and a big part of the job is keeping up to date and adapting to every new progression or announcement that we hear coming from Google or from the wider search community. This way of working has resulted in SEO professionals trying to predict where they think Google are going to go next, based on data, research and reading into what Google are doing and what they may be planning.

That is exactly what we’re going to be covering in this final part of our mini-series; where SEO is today, how search is moving, and what the future may hold.

At the time of writing (early March 2015), Google have just announced a huge change in their algorithm. This has again moved the goalposts and set the industry alight; they announced on 26th February, that from 21st April this year, they will be deindexing websites from smartphone search results if they don’t conform to Google’s own Mobile Friendly guidelines. This will come in the form of an algorithm overhaul, factoring in the calculations for its rankings whether a site is responsively designed, or has a mobile specific alternative.

This is going to have a huge impact on search and is an exercise in forcing the world to progress with the times. As the levels of mobile search sit around 40% of all search traffic (as of the end of 2014), Google are making it unacceptable not to have a website that not just works on a mobile phone, but works well and creates a user friendly experience. And if you don’t comply? Well, you’re not going to show up on any searches made from a smartphone anymore!

This was predicted with the onset of the “mobile-friendly” tag that has been appearing on mobile search results since last autumn, indicating to mobile searchers if a site was going to work properly on their phone or not. This, coupled with a series of guides on how to make sure your website is mobile friendly that were introduced by the Webmaster blog, was all the information that was needed to know that a big change was coming at some point.

This announcement was an unusual departure from Google’s usual method of introducing algorithm changes, which is to give no warning whatsoever and then release a brief press release explaining what happened after everyone’s visibility and rankings have nosedived!

SEO Going Forward – 2015 & Beyond

Google is constantly updating and tweaking its algorithm, as well as making slight changes to the search results page. These days it seems like Google wants the user to spend as much time as possible on the results page without clicking onto any sites. They’re doing this by providing a wealth of information to answer user queries on the results page itself.

A good example of this is their Rich Answers box, which pulls useful information from a trusted page, and displays it at the top of the results in its own box. The Knowledge Graph to the right hand side of the page displays lots of information about institutions and businesses so searchers can get essential details without having to click onto the site. This can be quite extensive; from maps to the nearest branches, links to social media profiles, names of the CEOs to stock prices. All this information serves to give the searcher the information they are looking for in the quickest possible time and without having to navigate through Google to other sites to find those quick answers.

Perhaps the biggest change to search is yet to come; researchers at Google are currently working on a new ranking system which rates the trustworthiness of a website, and ranks sites by how many facts they contain, rather than how many links point to them.

Google’s current algorithm decides the popularity of a website by monitoring how many other sites link to it, and how much activity based around it is happening on social media platforms. The issue with this is that sites containing little useful information can still rank well, despite all the changes Google has made over the past few years to ensure this doesn’t happen.

The Knowledge Vault

This new algorithm, still in its early development phase, will count the number of incorrect facts on a page in order to rate its trustworthiness. So the more false information a page contains, the lower its score will be. The software will use Google’s Knowledge Vault as the data source. The Knowledge Vault is a vast database of facts about pretty much everything, which Google has been building up for years by pulling information from the internet.

This system is still in its early stages and won’t come into effect for a long time, but it will be something we will be keeping our eye on, as it will mean another complete overhaul of the core fundamentals of how search works.

As you can see, SEO is a fast moving and constantly evolving discipline and we’re always playing catch up to Google when trying to make our websites the best they can possibly be. This is by no means an easy feat when the goalposts are constantly changing.

The importance of SEO is something I get asked about a lot. “Creating this content and managing the website is great, but is it really important for me and my business, in my industry?” The short answer would be “Yes”.

Taking care of your web visibility, making sure your site is performing as well as it can in the search engines and sharing good quality content is important for all businesses, no matter how non tech savvy or modern you perceive your industry to be!

The reason why? Well, your website and wider web presence is the best resource you’ve ever had for product marketing, public relations and managing your brand. In today’s world, the main portals for people to find answers to their queries are internet search engines. Because of this, top billing in these search engines has become a big area of competition. Not only does doing well in the rankings increase the hit rate to your site, and potentially impact sales, but your visibility across search engines is the best way to relate authority in your industry to the target audience.

As mentioned in the first part of this short series, SEO these days is about much more than just ranking highly in the search results. It has many other benefits to your business than just putting your site on the first page of Google.

Brand authority

Firstly, people trust search engines and their results; the concept of Social Proof plays a big part in why the top ranked sites perform better for their owners. “If Google says this company is the best then it must be.” It’s this trust that allows brand authority to be transferred simply from your search visibility. Secondly, continuous improvement of your website (making sure your site evolves continuously and never goes stale) makes for a better user experience.

As well as these overarching concepts, there is a big opportunity for good PR and brand awareness that stems from Google’s pressure for sites to provide good quality, interesting and useful content. Creating content around your industry has two huge benefits. First, the more relevant content that you have on your site, the higher your overall rankings will be as Google can see you’re making an effort to answer queries in a user friendly way. Second, good content will increase traffic to your website as people read and share it on their own sites and blogs or through social channels. Sharing of your content is in itself a ranking factor because it increases Google’s perception of authority you have within your market sector; if people are reading, sharing and linking to your content, then it must be useful.

Aside from the increased rankings and traffic rates, it is also generally good PR practice to keep up a good web presence and get actively involved in creating and sharing content across the web, keeping up to date with big industry developments and joining in with online trends and debates.

Other benefits of SEO include:

  • Getting ahead of your competition by making sure your rankings and web presence are light-years ahead of theirs
  • Making better use of analytics data and keeping a much tighter grip over how your site is performing and why, and how to improve it
  • A reduced spend on AdWords. The more organic visibility you have and the higher your rankings are, the less money you need to spend on short term visibility through an AdWords account

As you can see, a modern SEO strategy now encompasses many more aspects than just trying to achieve rankings. In the fast moving world of digital marketing and the internet in general, it’s essential you keep up to date with the very latest practices and don’t get left with a stale website that isn’t working for you soon after it’s gone live.

Having an SEO strategy is essential. It makes sure your website works for visitors, search engine webmasters and most importantly, for you and your business.

A Three Part Guide to Natural Search | Part One | What exactly is SEO?

Anyone who has even the slightest involvement in marketing or web management will have at least heard of the term SEO (Search Engine Optimization) at some point over the past few years.

The concept of SEO has been increasingly prominent in the digital marketing sphere since 2011. It has come a long way from its initial roots as a “dark art” that involved tricking or manipulating search engine algorithms into placing your site at the top of their ranking pages.

A lot has changed since then and SEO, as it exists today, is a different creature all together. Today’s SEO consultant is more likely to be found putting together content strategies and pouring over analytics data than placing thousands of links onto covert link farm websites and repeating a keyword 20 times on a webpage.

“Panda” and “Penguin”

The main cause of this big shift was two substantial updates to Google’s algorithm in 2011 and 2012, called “Panda” and “Penguin” respectively. These came down hard with severe penalties on SEO techniques using any covert activity. The impact of these algorithm updates revolutionised the industry and turned SEO into an activity based around keeping in line with Google’s rules and guidelines, rather than trying to break them!

SEO has continued in this vein and is now divided between what we call “onsite” and “offsite”. The onsite sphere is concerned with technical updates to a website to fully optimise it in line with Google’s webmaster guidelines. This ensures that the site has the best possible chance of ticking as many boxes in terms of ranking factors as possible (there are around 200 in all - so a lot of box ticking!). This encompasses everything from making sure meta titles accurately describe page content to minifying CSS to keep page loading times down.

Content outreach and sharing

The offsite sphere, however, is concerned with what we call “content marketing”. This is focused around making sure a website has a big network of other sites linking to it (this is great for rankings) and that the content is being shared across the web, including social media platforms.

It’s this content outreach and sharing that Google has put huge emphasis on over the past few years, as they want people to make their sites useful and helpful for web users. If your site fits this brief, then Google will be more confident in displaying it as one of the top results for queries in the field.

SEO should be thought of as a holistic process that not only fits into web design and development, but also into your digital marketing and wider PR activity; more of a framework than a linear process and something that is kept in mind when doing anything on the web. “Users First, Search Engines Second” is our mantra here at the SEO department of Verto, and it’s a phrase that really sums up the position of SEO in today’s digital world.

Make your site the best it can possibly be for the user and you will be rewarded in the SEO stakes.

Why can’t the 2601/2642 series slides be flat mounted?

Author: John Whittlesea, Technical support manager


25th Mar 2015


The main reason we do not recommend the 2601 or 2642 slides be used in flat mount applications is the minimal ball wrap on the intermediate member.

The I-beam construction of the intermediate member allows the 2600 cross section to handle loads in vertical/side mount applications when the force is applied directly into the ball race.

If used in flat mount applications, the outer member and ball retainer could easily pop out of the intermediate member when the forces are directed away from the ball race and into the ball wrap. This is possible even if the stated load rating were reduced by 75%. Minimal material thickness, ball size, outer ball wrap are other design components that reduce these slides’ ability to handle loads in the flat mount position.

If you need further help please contact us by emailing [email protected] or call your local Accuride office.
