INA full complement cylindrical roller bearings, two-row

INA SL024912 cylindrical roller bearings have 3 ribs on the inner ring and 0 rib on the outer ring. As a result, axial displacements of the shaft relative to the housing can be compensated within certain limits. During rotational motion,length compensation occurs without constraint in the bearing between the rollers and the raceway without ribs and is therefore practically free from friction. The maximum axial displacement of SL024912 is 1 mm.

INA SL024912 bearings are used as non-locating bearings. They cannot guide the shaft axially in either direction.
