The ACM Series Angular Contact Ball Bearings are high-precision components specifically engineered for machine tool main spindles and other ultra-high-speed applications. Featuring an optimized 15-degree or 25-degree contact angle, these bearings achieve exceptional rotational accuracy and minimal heat generation at extreme speeds. Their advanced cage design and specialized grease options enable stable operation under severe conditions.
The series incorporates special materials and heat treatment processes that provide enhanced durability and dimensional stability under thermal variations. Particularly suitable for CNC machining centers, precision grinders, and high-frequency motor spindles, ACM Series bearings deliver superior performance where maximum speed capability and minimal thermal deformation are critical requirements for manufacturing precision.
