Producing a Superior Roller Guide


In comparison to presently available linear guides, the EXRAIL® slide guide provides smoother movement, higher load capacity and damping. It uses multiple small diameter needle rollers–it has more rollers in less space than other linear bearings – reducing dynamic frictional resistance and range of fluctuation of dynamic frictional resistance. Its rollers are in contact with lubricated resin material during circulation, extending lubrication. The EXRAIL® has a 1.5 to 2 times higher static load rating as well as allowable static moment in the rolling, pitching, and yawing directions in comparison to other products on the market. The EXRAIL® retainer prevents skews and friction ensuring smooth circulation.
