5211-2RS Double Row Angular Contact Ball Bearing Applications:
1. Oil pump, Roots blower, air compressor, all kinds of transmission, fuel injection pump, printing machinery,
2. Planetary reducer, extraction equipment, cycloid reducer, food packaging machinery, welding machine, soldering iron,
3. Square box, gravity spray gun, stripper, half shaft, inspection and analysis equipment, fine chemical machinery.
5211-2RS 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.
5211-2RS Double Row Angular Contact Ball Bearing Advantages:
1. High-quality steel: Ultra-clean steel bearings extend up to 80% of life.
2. Advanced grease technology: Seiko grease, can extend life and performance.
3. Super finished raceway: special grinding to reduce noise, improve lubricant distribution and life.
4. Patent seals provide protection against pollution in the worst environments.
