High Precision NSK Double Row Angular Contact Ball Bearing 5311
Overview:
Angular contact bearings are able to support radial load and axial load. As single row angular contact ball bearings can only support axial load in single direction, matched bearing mounting is often adopted to them as matched parts of bearings, preload for them is more convenient.
Contact angles: C-15°, A5-25°, A-30°, B-40°
Cage materials: brass, synthetic resin, molded polyamide resin.

Benefits:
Single-row angular contact ball bearing - suited to work in lower operating temperature and high speed with a heavy thrust load. Can be mounted in a duplex arrangement. The refined bore tolerance give a higher life.
Double-row angular contact ball bearing - excellent axial and radial rigidity in confined space.
Applications :
Aircraft, construction, agriculture, machine tool, automotive applications and general industry.
