Single-row Angular Contact Ball Bearings
Get Price Quote
The raceways of both the inner and outer rings of this bearing type are made with a set contact angle. Single-row Angular Contact ball bearings can sustain radial, axial or composite loads, however, any axial load must be in one direction.Larger contact angle type has better axial load capability. Small contact angle type has higher permissible speed capability. This bearing type is generally used in adjacent positions. These bearings are designed with three contact angle classifications as shown in Table 1. Normally, contact angle A design and B design are fitted with a cage as shown in Table 2. High precision (JIS/ISO class 5 or higher) may be fitted with a machined cage of bronze or phenolic resin or a polyamide cage. Contact angle C design are generally applied high precision, JIS (ISO) class 5 or higher, and are fitted with a machined phenolic resin cage or a polyamide cage.
