For more than 70 years, Thomson has been producing precision-ground linear shafting for its Linear Ball Bushing® Bearings.
While shafts may appear the same to the untrained eye on the surface, there are significant performance differences due to the manufacturer’s selected standards and the manufacturing processes used to achieve them. Thomson 60 Case was developed and is continually enhanced because of our goal to provide a consistent finish, roundness, straightness, cylindricity case hardness and depth on all shafting for the demands of a linear bearing. Unlike common shafting, Thomson 60 Case shafting is manufactured to the highest quality standards in an ISO 9000:2000 registered facility. Our techniques have been continuously upgraded with proprietary knowledge gained from more than 70 years of manufacturing experience. Using Thomson 60 Case with Thomson Ball Bushing Bearings ensures optimal bearing performance and travel life.
Maximize the performance and life of your linear motion systems by knowledgeably choosing the optimal shafting. All it takes is becoming familiar with a few key considerations.

Properly mounting round shafting is required for it to be used as a linear guide. Watch this video to learn about the most common shaft mounting methods.
What is the difference between round rail and square rail? How do you know which one is more appropriate for a given application? How do you size them? Learn the basics of linear guide technology and how to size them for your next application. Plus - get a guided tour through the new online Linear Guide Component Tool.
In this webinar, you will learn: Linear Bearing Types, Typical Applications, Design Considerations, Application Requirements, Optional Features, and Design Calculations.
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, or profile rail, linear guide in the 1970s, the design engineer has been faced with the pivotal question: round or square?
How to choose between the main types of linear technologies, and how to design automation systems that deliver optimal performance using design requirements, rather than cost, as the primary consideration in selecting linear components.
Specifying the right bearing for a given application is necessary to save time and excessive costs. Understanding the tradeoffs of each bearing type is important to accurately size and select the right bearing for your application. This article will provide an overview of the major types of linear bearings and guides, explain how to specify them for specific applications and describe how to trouble-shoot common application problems.
