1、 Harbin Bearing - Introduction to Composite Bearings

1. A combination bearing is a single bearing consisting of two or more rolling elements that jointly bear loads in several directions. The combination bearing has a compact structure that can limit the axial displacement of the shaft and housing, with a low limit speed, and is suitable for components with limited dimensions.

2. Composite bearings can withstand high radial and axial loads, with high precision and rigidity.

IIHarbin BearingApplication of Composite Bearings

1. ZARN and ZARF types are combination bearings of needle rollers and bi-directional thrust cylindrical rollers, suitable for screw support in CNC machining centers and other applications;

2. ZARF outer ring is used for flange installation and is suitable for screw support in CNC machining centers;

3. YRT type is a combination bearing of cylindrical rollers and bi-directional thrust needle rollers, suitable for rotary supports such as CNC milling machines;
