Product Description

Super Precision Cylindrical Roller Bearings Nnu4920k with Solid cage

PRODUCT DESCRIPTION
ZYS cylindrical roller bearings belong to line contact, with high 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 including two structure 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.

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.
