Single-row Angular Contact Ball Bearing

Single-row Angular Contact Ball Bearing

The Single-row Angular Contact Ball Bearing can bear the axial load in one specific direction. Its axial loading capacity depends on the contact angle α. The bigger the contact angle α is, the higher its axial bearing capacity will be. The standard contact angles include 15°, 25°, and 40°.

The point of contact of Single-row Angular Contact Ball Bearing is not located at the bottom of the raceway. There is a specific axial component force when it bears the radial load, so it is necessary to use it in pairs or sets typically. The filling angle of the ball does not restrict the number of balls. Compared with the Deep-groove Ball Bearing, it can hold more balls; therefore, it has higher stiffness and higher load-carrying capacity.

This kind of Single-row Angular Contact Ball Bearings is classified into Separable Bearings and Non-separable Bearings.

The Non-separable Angular Contact Ball Bearings can be classified into the following three essential structures:

α=15°, Type 70000 C
α=25°, Type 70000 AC
α=40°, Type 70000 B

The solid metal cages are typically used in the Single-row Angular Contact Ball Bearings. In some high-speed scenarios, the solid cages are usually made of phenolic resin; however, their working temperatures should not be higher than 120

The single-row angular contact ball bearing can bear a radial load and an axial load in one direction, and it can bear a single axial load in one direction; under the radial load, its axial component load will be caused. Therefore, the single row angular contact ball bearing should be matched with the other bearing to bear the axial load in the opposite direction. So, 2, 3, 4 or even 5 angular contact ball bearings are usually matched together for use, and the angular contact ball bearing has a high limiting speeds.

The contact angles of CHG light series precision angular contact ball bearings are 15° (Code C), 25° (Code AC) and 40° (Code B); for the angular contact ball bearings, the contact angle is greater, the axial load capacity is larger, but the bearing limiting speeds is lower. Therefore, the bearing with the contact angle of 15° is used on the shaft with high speeds and small axial load; on the contrary, the angular contact ball bearings with the contact angle of 25° or 40° should be used.
CHG precision angular contact ball bearings can be divided into 3 series of high-speed angular contact bearings (standard series), ultra high-speed angular contact ceramic ball bearings, and high speed sealed angular contact ball bearings.
