Overview
單列角接觸球軸承
這些單列角接觸球軸承可承受同時作用的徑向和軸向載荷，而軸向載荷只能作用在一個方向上。 根據不同的型式，這種軸承能在高速，甚至極高轉速下運轉。 比深溝球軸承更能承受單向較大的軸向力。
Key features
- 高速能力；可承受相對較高的徑向載荷和較大的單邊軸向載荷
Typical applications
- Machine tool spindles and support shafts
- Pumps and compressors
- High-speed motors
- Precision gearboxes and robot drives
Selection guidance
Select by contact angle, arrangement, preload, precision class, axial load direction, and operating speed.
