500 Series Ball

Thomson 500 Series Ball Linear Guides provide long life, exceptional rigidity, high dynamic and static load capacities, accommodation for high moment loads, high running accuracy, multiple sealing options and multiple lubrication inlet options.  The resulting reduction in vibration extends machine and tool life and has a direct effect on operational efficiency.Learn more about 500 Series Ball >

500 Series Ball Spacer

500 Series Ball Profile Rail carriages are now available with ball spacer elements that significantly reduce the running noise of the carriage. The noise reduction is achieved by inserting plastic discs between each ball bearing. This reduces noise by preventing the balls from contacting each other as well....Learn more about 500 Series Ball Spacer >

500 Series Roller

The Thomson 500 Series Roller Linear Guide offers higher load carrying capacity, lower elastic deformation and lower wear with minimum rolling friction.  Rigidity is achieved by using the equivalent of a back-to-back bearing arrangement, complemented by special rollers that are crowned to prevent roller edge loading when misalignment is present.Learn more about 500 Series Roller >

400 Series Ball


Thomson’s 400 Series Ball Profile Rail is a cost effective, transport grade rail solution for cost-sensitive applications.  It is an excellent drop-in replacement with industry-standard envelope and hole patterns. Double-faced ball track bearing arrangements provide compliance during installation as well as equal load carrying capacity in all directions.
