Product Description

General information of ZYS cylindrical roller bearing

ZYS cylindrical roller bearing belongs to line contact, with higher capacity and rigidity than angular contact ball bearings (including multiple sets of bearings). But the allowable speed is lower. Therefore, cylindrical roller bearings are used in the medium, large-scale machine tool with large load, high rigidity and low speed. 
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 serve as fixed supporting. The most commonly used cylindrical roller bearings in the machine tool are double cylindrical roller bearing with tapered bore.  This kind of bearing can bear greater radial load with detachable inner and outer rings, and can not bear the axial load , so they are often used with double-direction angular contact thrust ball bearings which bear axial load.

Double row cylindrical roller bearings with tapered bore are matched with tapered shaft neck of spindles. During the processes of bearing assembly, the axial movement of inner ring can swell the inner ring, and then the internal radial clearance can be changed and the bearing preload will be acheived. 
As for the N10 and NN30 series of cylindrical roller bearings, the inner ring has shoulder, the outer ring can be separated. For double row cylindrical roller bearings used with oil lubrication, a circumferential oil groove and three symmetric lubricant holes are set in the middle of outer ring, marked W33.
