Ufine Bearing CO., LTD is a Chinese bearing manufacturer which is located in the city of JiNan - the provincial capital of ShanDong province, China. The enterprise professional concentrates on manufacturing all kinds of bearings as our own brand “UFE”, mainly include roller bearings and ball bearings. And we have also set a long-term cooperation with several famous bearing companies in the world, such as NSK, NACHI, KOYO, INA. The products we produce have already been sold to all over China and also abroad, the bearing brand “UFE” enjoys high states in the rolling bearing industry of China and is highly praised by our customers.

Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.

The axial load carrying capacity of angular contact ball bearings increases as the contact angle increases. The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the combined load is transmitted from one raceway to another, and a line perpendicular to the bearing axis

The most commonly used designs are:

single row angular contact ball bearings

double row angular contact ball bearings

four-point contact ball bearings

In addition to the bearings presented in this section, other angular contact ball bearings include:

Super-precision angular contact ball bearings

Double row cam rollers

Fixed section angular contact ball bearings

Hub bearing units
