Linear guide with ball bearing RK series

steelV-shaped rail

The recirculating linear ball bearings type “RK” are mainly composed of three parts. The former is a central body in coro hardened steel (hardness HRC 60 ± 2) whose purpose is to hold the charge.The balls are conveyed to the V-shaped rolling track of the rail, suitably kept by a polyammide block as to hold and give them the direction. The recirculating linear ball bearings “RK”, once coupled with rails “GR” or “GRD”, allow linear movements limited only by the length of the rails themselves. It is important to mention the possibility to use on the same way, several units with independent motion. Max. admitted speed: 120 m/min. Max.admitted acceleration: 50 m/sec2 The recirculating linear ball bearings “RK” (size 6 ÷ 9) can be supplied with damping elements (RKD) to reduce the noisiness. This reduce however the load capacity.
