Cylindrical Roller Bearings


  • ZYS cylindrical roller bearings include two series: single row cylindrical roller bearings N10 and double row cylindrical roller bearings NN30. The bearing bore also has two kinds: cylindrical bore and tapered bore.

    Single row cylindrical roller bearings, as free supporting, are usually matched with angular contact ball bearings which are as fixed supporting. Those usually used on precision machine tool is double row cylindrical roller bearing NN30K series whose tapered bore degree is 1:12. This kind of bearing can bear greater radial load, and can not bear the axial load because of the detachable inner and outer ring, so they are often used with two-direction angular contact thrust ball bearings which bear axial load.
