2. Medium and large single row/double row/four-point angular contact ball bearings ZZ 2RS
1. Angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis. This means that they are designed to accommodate combined loads, I. E. Simultaneously acting radial and axial loads.

2. The axial load carrying capacity of angular contact ball bearings increases with increasing contact angle. The contact angle α Is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the load is transmitted from one raceway to another, and a line perpendicular to the bearing axis.

3. Angular contact ball bearings 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

4. Types:
1. Single row angular contact ball bearings
2. Double row angular contact ball bearings
3. Four-point contact ball bearings

5. Mounting

Single Row And Double Row Angular Contact Ball Bearing ( Z, ZZ, RS, 2RS, NPP, KDD, P, PP, N, NR)
Angular contact bearing, double row, single row,
Item No: 3805 2RS
Angular contact ball bearing is composed of outer ring, inner ring, steel ball and cage, structure can be divided into single row and double row, seperated type and non-seperated type; Speed can divided into high-speed and low-speed, precision can be divided into high precision and normal precision, mainly used to bear the load combined of radial and axial, and sometimes it can bear pure axial load with a high speed. The number of loaded ball is more than the deep groove ball bearing, the largest load rating in the ball bearing, rigidity and smooth operation.
