In most cases, the outer ring of bearing such a fag mouth locked, and can not seal ring groove thus formed, leading many used in the machine tool spindle bearings on the angle of contact with Qiu can not be used as the other bearing on the other Zhuji as lubrication. If installing a set of auxiliary lubrication system, not only to increase costs and make the structure more complex machine.

Four-Point Contact Ball Slewing Ring Bearing As SOCARE BEARING one main series, this kind of Slewing bearings are skilfully just as clay in the hand of potter. This kind of Slewing bearing is the most common type, it is made up by two Rings, Balls & Supports, with compact conformation, light weight, the Steel Balls are Four Point Contacting with the arc Raceway, it can bear both Axdial & Radial load and the moment at the same time. It often be used on Rotary Reclaimers,

ntn bearing angular contact ball bearings is mainly used in machine tool spindle. In most cases, locking the outer ring of this bearing the mouth and can not seal the resulting circular groove, so many used in the machine spindle angular contact ball bearings can not be used for other hosts as the other bearings as lubrication.If installing a set of auxiliary lubrication system, not only to increase costs and make the structure more complex machine.
