PRODUCT CENTER

The factory produces over 1000 specifications and models of precision bearings with various purposes and special performance, ranging from inner diameter 8mm to outer diameter 620mm

Deep Groove Ball Bearing

Its characteristics are low frictional resistance, high rotational speed, and can be used on components that can withstand radial loads or combined loads of radial and axial forces.

Tapered Roller Bearing

Tapered Roller Bearings belong to separable bearings, and both the inner and outer rings of the bearing have conical raceways.

Spherical Roller Bearing

Spherical roller bearings have two rows of rollers that are primarily subjected to radial loads and can also withstand axial loads in either direction.

Angular Contact Ball Bearings

Angular Contact Ball Bearings can undertake both the radial load and axial load in the mean-time. Such bearings can work at a high rotational speed.

Cylindrical Roller Bearing(2)

Cylindrical roller bearing is a type of separable bearing, which adopts a parallel arrangement of rollers in its internal structure.

Cylindrical Roller Bearings

Wheel hub bearing

Wheel hub bearings are components used at the axle of a car to bear weight and provide precise guidance for the rotation of the wheel hub.

Needle Roller Bearings

Needle roller bearings (needle bearing) is a cylindrical roller with a roller bearing, relative to its diameter, roller both thin and long.
