Super Precision Angular Contact Ball Bearings S71912 ACDGA/P4A

Super Precision Angular Contact Ball Bearings S71912 ACDGA/P4A

The S71912 ACDGA/P4A is a super precision angular contact ball bearing with a 60mm bore and 85mm outer diameter, crafted from durable chrome steel. Its compact 13mm width makes it suitable for space-sensitive applications.

With a 25° contact angle and extra light preload, it handles radial loads up to 4185 lbf while spinning smoothly at 36,000 RPM. The sealed design keeps grease in place, reducing maintenance needs.

The phenolic cage ensures quiet operation and long service life, even in temperatures from -30°C to 110°C. This bearing is interchangeable with SKF models, offering a reliable replacement option.

Ideal for high-speed applications like machine tool spindles or precision instruments, where accuracy and low friction are key. Weighing just 0.2kg, it balances lightweight design with robust performance.

It can be used in matched sets for back-to-back, face-to-face, or tandem configurations, providing flexibility for various load requirements. The P4A tolerance class guarantees exceptional precision.
