Ball Chains: Two things you might not know

April 3, 2015 By Danielle Collins 1 Comment

Radial bearings have used ball cages for nearly a century, but this technology was only introduced to profiled rail guides within the last two decades. THK pioneered the way, launching its Caged Ball® LM Guide in 1996, and other profiled rail manufacturers soon followed suit with ball chain and ball spacer designs. Now, virtually every style […]

When to use cam roller guides. (Hint: it’s more often than you think.)

March 13, 2015 By Danielle Collins Leave a Comment

With so many linear guide choices—from roller rails to plastic wheels—deciding which technology is right for your application can be difficult. On one hand, not every application requires machine tool rigidity and the ability to move a small car. But on the other hand, most applications require a guide that can withstand high duty cycles […]

High-class linear guides: How industry quantifies rail accuracy values

February 5, 2015 By Danielle Collins Leave a Comment

I once overheard a colleague, relatively new to linear motion and eager to be helpful, tell a customer, “H stands for our high-class rail.” While the thought of a “high-class” rail was amusing, technically she was correct. In profiled linear guide terminology, H is the designation for high class … … high accuracy class, that […]

Linear Motion in the Third Industrial Revolution

December 11, 2014 By Danielle Collins Leave a Comment

According to The Economist magazine, a third revolution is coming for the manufacturing industry, ushered in by 3D printing, new materials, and collaborative manufacturing services. Anyone who has watched the 3D printing industry develop over the past decade, or even the past five years, will likely agree. Gartner forecasts that worldwide shipments of 3D printers […]

We’ve Got You Covered: A Quick Guide to Platings and Coatings

November 14, 2014 By Danielle Collins 4 Comments

Machine builders and end users have many factors to consider when choosing linear motion components and systems – travel length, speed, acceleration, positioning accuracy and repeatability, just to name a few. But sometimes the most challenging requirement isn’t a traditional application spec. It’s the environment that the system will be working in. Many industries have processes […]

How to calculate linear bearing life

October 30, 2014 By Danielle Collins 10 Comments

When selecting linear guides, have you ever seen a disclaimer in the catalog or on the manufacturer’s website regarding dynamic load capacities? It typically reads something like this: Dynamic load capacities are based on 100,000 m of travel. When comparing to products for which load capacities are based on 50,000 m of travel, multiply the 100,000 m […]

Ultra-low Profile Roller Guides

March 6, 2009 By Miles Budimir Leave a Comment

The RB series of ultra-low profile roller guides from NSK Precision America are designed to meet the rigorous demands of the machine tool industry. Compared with NSK’s conventional RA series roller guides, the series offers a 26% reduction in overall height, which helps downscale equipment and lower the center of gravity of precision/positioning tables. Optimizing […]
