Linear Guides 

We offer both ball and roller bearing type linear guide systems.  A series of balls continuously circulates within the block (or carriage) while the block moves in a linear fashion along the rail for the ball type guides.   Roller guides operate in a similar fashion but in place of the balls are roller elements.   Both of these products are typically used in machines, devices, and mechanisms that require smooth accurate movement with very low frictional drag.

Roller Bearing Products

Linear Guides (Roller Bearing Type) 

Roller Bearing Linear Guides provide high capacity with the least amount of deflection under load while offering low friction guidance of payloads for machine applications. With 4 rows of recirculating rollers engaged in a precision ground rail, these bearings provide load capacity in all directions.

  • Industry standard sizes 25 to 55
  • High load carrying capacity
  • Very little deflection under load resulting in high stiffness and rigidity 
  • Rail lengths to 4000mm with splicing available for longer lengths
