Sell four-point contact ball bearing

Description

Four-Point Contact Ball Bearing Because the inside and outside raceway of angular contact ball bearing can have a relative displacement in the horizontal axis, so it can be subjected to radial and axial load - joint load(single row angular contact ball bearing can only bear one direction axial load, so it is often installed in pairs). According to bearing forms and use condition cage is usually brass and synthetic resin. Four point contact ball bearing is separate bearing and is angular contact ball bearing which can bear axis load in two directions. His inside and outside ring road are peach-section. When endured pure radial load or no load, ball and ring is four point contact. When endured pure radial load, ball and ring is two point contact. Now, it can bear axis load in two directions. This kind bearing can bear torque. It have the function of single and double row angular contact ball bearing. This bearing can work normally only two point contact. The bearing will be two point contact in the occasion of pure axis or great joint axis load. The bearing have high limit speed and be suitable for high speed occasion.
