ZWO Cylindrical roller bearings

Cylindrical roller bearings use rollers for rolling elements; and therefore has a high load ; The rollers are guided by ribs on either the inner or outer ring; therefore these bearings are also suitable for high speed applications; The inner and outer rings can be separated to facilitate assembly; and both can be fit with shaft or housing tightly; If there is no ribs;either the inner or the outer ring can move freely in the axial direction; Cylindrical roller bearings are therefore ideal to be used as so-called "free side bearings" that absorb shaft expansion.
