Selection of slewing ring bearing fit should focus on the following four points:

(1) the circumferential surface of bearing rings should have good support and force uniform, in order to reduce the distortion, and give full play to the carrying capacity of the bearing.

(2) rings in their mating surfaces cannot slide along tangential direction, slewing ring bearing otherwise it will damage the mating surfaces.

(3) the free end bearing must adapt to changes in the length and the shaft and the bearing seat hole phase, which must have the ability to adapt to the axial position within a certain range of swimming.

(4) must pay attention to the  reali slim bearings installation and removal easy, spending is labor-saving and time-saving province. The operation of bearings, hand Khan will become the cause of rust. To note that the clean hands operation, the best to wear gloves.

The life of the bearing is with the care and maintenance is very important, because it is related to the bearing life, work efficiency. Maintenance of sealed bearing maintenance use, will bring a lot of benefits, for example can bring about high production efficiency, producing more high quality precision products, maintenance can extend the life of several times to save you a re purchasing cost.‍
