Most linear bearings incorporate ball bearings (usually of metal) to reduce friction between moving parts. Of these designs, most bushings, ball splines, linear guides and slides recirculate balls. As ...

Precise movements are made with precision slides. Reciprocating linear bearing accuracy, the possible runout in any plane, is typically as low as 0.005 in./in. Because linear bearings are only as ...

Place a recirculating-ball bushing on a shaft and what do you get? Frictionless movement of the shaft. But, create grooves along the axial length of the shaft that correspond to the radius of the ...
