5312-2RS Double Row Angular Contact Ball Bearing Features:
1. Double row angular contact ball bearings generally use nylon cage or brass solid cage
2. Double row angular contact ball bearings can withstand biaxial loads
3. The installation of double row angular contact ball bearings is more complicated than that of deep groove ball bearings. Most of them are
installed in pairs, and preloading is required.
4. In general, small preload load should be chosen for high speed and large preload load for low speed.

5312-2RS Double Row Angular Contact Ball Bearing Working Principle:
1. Double Row Angular Contact Ball Bearing can bear radial load, radial load and axial load.
2. When it only bears radial load, the contact Angle is zero. When the deep groove ball bearing has a large radial clearance.
3. It has the performance of angular contact bearing and can bear a large axial load.
