Overcoming Linear Motion Bearing Misconceptions
Failing to consider common pitfalls when designing with linear bearings will inevitably result in subpar machine performance. In Overcoming Linear Bearing Misconceptions, learn from Thomson Director of Engineering for Rails, Guides and Components, Al Ng, what some of the most common design errors are, and how to avoid them en route to obtaining maximum performance from your machine.

Round or Square?
Since the introduction of the original round rail Ball Bushing linear bearing invented by Thomson in the 1940’s, there has been steady development in the field of recirculating ball linear guides. Advancements in load capacity, life and ease of manufacture allowed an ever-widening range of applications to benefit from nearly friction free linear guidance. Since the introduction of the square linear guide in the 1970’s, the design engineer has been faced with the pivotal question: round or square?

How to Choose a Linear Rail and Carriage for Linear Motion
Linear rails come in basically two types, round and square. The criteria for choosing one over the other is no different than choosing any other machine component; spec out the design, define the system’s objectives, and work from past successes and mistakes. But anyone short on experience can make more mistakes, so a condensed course in selecting the proper rail for any application to keep design errors to a minimum is in order.

A Precise Solution to Motion Control Challenges
In most industries, managers face a shortage of qualified engineers and maintenance staff to properly support and maintain equipment. Consequently, their engineers face multiple challenges when designing rugged, reliable, and quiet machines that meet these new motion control demands. One way design engineers are meeting these challenges is with components that the motion control industry refers to as precision bearings.
