Single-row angular contact ball bearings

Single-row angular contact ball bearings

Single row angular contact ball bearings can carry the axial load in a particular direction.

The contact point of such bearing is not at the bottom of the raceway, so when such bearing carries radial load, a certain axial force will be produced and the inner and outer rings will be removed, and so it should be used in pairs. Because the number of balls is not limited by the filling angle, compared with the deep groove ball bearing, its number of steel balls is more, and so the rigidity is better and the carrying capacity is higher.

Product introduction

Single row angular contact ball bearings can carry the axial load in a particular direction. The axial load capacity is determined by its contact angle α, namely the greater the contact angle α, the larger the axial carrying capacity. The contact angles commonly used are 15°, 25° and 40° respectively.

This kind of bearing is divided into two types: separable bearing and inseparable bearing.

The separable bearing is divided in two types: type S70000 and type SN70000 with inner and outer rings separable respectively. The inner and outer rings can be installed separately, so this kind of bearing is suitable for condition in which the space of the installing site is limited.

The inseparable angular contact ball bearing has the following three structures:

α=15°，type 70000 C.

α=15°, type 70000 C.

α=25°，type 70000 AC.

α=25°, type 70000 AC.

α=40°，type 70000 B.

α=40°, type 70000 B.

Single row angular contact ball bearings use generally metal solid cages. Under high speed operation, the solid cage of phenolic resin material is generally used, and the temperature used is not more than 120 ℃.
