角接触球轴承
角接触球轴承的滚道倾斜成一定角度,设计用途为承受单向的径向与轴向联合载荷。接触角(通常为 15°、25° 或 40°)决定其轴向承载能力 —— 角度越大,可承受的轴向载荷越重。该类轴承常成对或成组使用以承受双向载荷,适用于机床主轴、汽车变速箱及对精度和刚性有高要求的泵类设备等应用场景。
Angular Contact Ball Bearings feature with raceways offset to handle combined radial and axial loads. Designed for high-speed applications, they require paired installation for bidirectional axial load support. Commonly used in machine tool spindles, automotive transmissions, and aerospace systems.
Double Row Angular Contact Ball Bearings feature two rows of balls in a common outer ring with a 30° contact angle, enabling bidirectional axial load handling. Non-separable design with integral ribs ensures precise alignment. Ideal for high-speed, high-stiffness applications like machine tool spindles and automotive differentials.
Double Row Sealed Angular Contact Ball Bearings feature two rows of balls with a 30° contact angle, sealed with rubber (2RS) or metal shields (ZZ) to retain grease and exclude contaminants. Non-separable design handles bidirectional axial loads. Ideal for high-speed, contaminated environments like robotics and conveyor systems.
