Wheel and pin bearing KR KRV

Description

Wheel And Pin bearing Series is bolt type rolling wheel bearing. This kind of bearing is fill-up running pulley framework, and the rollaway nest of stud shaft is quenched. By way of avert that stress focusing, the outside circle surface of contact roller is arc, there is two unitary cover on the outside circle, the direction of axes is led by roller. The head of stud shaft and lateral obstructive circle supplies support to direction of axes for outside circle go through rollers. Wheel And Pin bearing Series fit heavier radial load condition, owing to outside circle is axial led by running pulley, so that it could bear heavier axial load, so allow to make comparatively high-speed running. But owing to be fill-up running pulley, so often needs to supplement lubricant, it may append lubricant go through the eyelet on the central axoplast and both ends of mandril. KR series of Wheel And Pin bearing Series is rolling pin keeping etagere module bearing, it could bear heavier load in mid-speed rev condition. Owing to the inside of bearing has more space to store up lube, so that the periods of lubrication can extend. KRV series of Wheel And Pin bearing Series is fill-up wheel pin bearing, it could bear heavier load in low-speed rev condition. But it must often append lube. The bearing material is bearing steel, there is no need to make maintain. The production made in Zhejiang Lishui in China.
