The lengt of life of angular contact ball bearing relative to installation.

How to prolong angular contact ball bearing service life?

(1) Bearing installation should be in clean room, bearing to carefully matching, bearing with spacing ring should pass grinding, and to maintain the internal and external ring spacing ring contour premise, spacing ring parallel degree should be controlled in 1 um the following

(2) Bearing before the installation, should be cleaned, when cleaning, inner ring slope up, hand induction flexible, no stagnation feeling, dry, in the specified amount grease, in the case of oil mist lubrication should be put in a small amount of oil mist oil;

(3) Bearing installation should use special tools, stress even, it is strictly prohibited to hammer;

(4) Bearing should be stored clean and ventilated, no corrosion gas, relative humidity do not exceed 65%, long-term storage should be regularly rust

7324AC angular contact ball bearing dimensions:

Product description:

Angular contact ball bearings are able to support radial lode and axial lode. As single row angular contact ball bearings can only support axial lode in single direction, matched bearing mounting is often adopted to them. As matched pairs of bearing, preload for them is more convenient. Retainers are made of brass, synthetic resins or other subject to individual bearing features and application conditions.

Features:

1) Load capacities are higher than deep groove ball bearings of same dimensions

2) Used for bearing radial-axial combined loads or pure thrust loads

3) Low operating friction and high limiting speed

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.

 Angular Contact Ball Bearings with contact angles of 15° (Symbol C) and 25° (Symbol A5) are primarily for high precision or high speed applications, and machined brass or synthetic resin cages or molded polyamide cages are used.
