Welcome to HK QIFAN INT’L TRADE LIMITED
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
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 Bearings belong to separable bearings, and both the inner and outer rings of the bearing have conical raceways.
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 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 is a type of separable bearing, which adopts a parallel arrangement of rollers in its internal structure.
