I. Structure and characteristics 1. Double row design: double row thin wall bearings adopt two rows of rolling element design, this structure makes the bearings have higher load carrying capacity and stiffness, and can withstand greater loads and impacts.

Three-row roller slewing bearing is one of the main bearings in our company, the main parts include outer ring, inner ring, isolation block, cage, three rows of rollers, sealing device and so on. According to the structure, they can be divided into three kinds: external gear, no gear and internal gear.

The installation of bearings is very important during the use of bearings and is a key factor in determining the service life of bearings. When installing bearings, you need to pay attention to the following key issues to ensure correct installation and long-term stable operation of the bearings:

The precision ball bearings produced by CHG can be divided into 4 series: 618 series, 619 series, 718 series, 719 series. With the inner diameter range from 100mm to 950mm, and the precision is divided into P6, P5, P4 and P2.

Four row cylindrical roller bearings FCDP164226800. Alternative to part number 820RV1117. Sizes: 820mm*1130mm*800mm. Used for cold rolling mill machine. Back-up roll bearing.

Compared with C-type bearing, A-type angular contact ball bearing has an enough radial clearance to form a sufficient contact angle to carry the axial load. The contact angle for the standard bearing is 30°.
