466953 Bearing Product Overview & Core Advantages
The 466953 metric angular contact ball bearing is a precision single-row bearing engineered for applications requiring high rotational accuracy and robust load capacity. Its defining feature is the 25° contact angle, which enables it to efficiently support combined radial and axial loads in one direction. Manufactured to a P6 (ABEC-3) tolerance class, this bearing offers exceptional dimensional stability and running accuracy, making it ideal for high-speed, high-reliability machinery. The open design, combined with a lightweight nylon cage, facilitates optimal lubrication and contributes to its impressive limiting speed performance.
