Angular Contact Ball Bearing

详情

Angular contact ball bearings General introduction :：Angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis. This means that they are designed to accommodate combined loads, simultaneously acting radial and axial loads. The axial load carrying capacity of angular contact ball bearings increases with increasing contact angle. The contact angle α 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 load is transmitted from one raceway to another, and a line perpendicular to the bearing axis hrbqc angular contact ball bearings are produced in a wide variety of designs and sizes. Those commonly used and included in this catalogue are single row angular contact ball bearings double row angular contact ball bearings four-point contact ball bearings Four-point contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads acting in both directions. Radial loads can be supported up to a certain fraction of the axial load. These bearings take up considerably less axial space than double row bearings. hrbqc four-point contact ball bearings of the QJ design have a contact angle of either *5° or *5°. The inner ring is split. This enables a large number of balls to be incorporated in the bearing thus giving the bearing high load carrying capacity. The bearings are of separable design, ***** the outer ring with ball and cage assembly can be mounted separately from the two inner ring halves. 1. ID *0 to **0 mm 2. OD *6 to **0 mm 3.
