Super Precision Angular Contact Ball Bearings 71907 CD/P4AQBCA

Super Precision Angular Contact Ball Bearings 71907 CD/P4AQBCA

The 71907 CD/P4AQBCA is a super precision angular contact ball bearing, measuring 35mm by 55mm by 40mm, crafted from durable chrome steel. It features a 15° contact angle and comes in a matched set of four bearings for balanced performance.

Designed for angular loads, it handles radial loads up to 5738 lbf and spins smoothly at speeds up to 56,000 RPM. The phenolic cage ensures quiet operation and long service life.

Its open design allows easy lubrication, while the extra-light preload (Class A) ensures minimal friction. Ideal for high-precision applications like machine tool spindles or medical equipment.

The bearing operates in temperatures from -30°C to 110°C and weighs just 0.3kg. Compliant with P4A tolerance standards, it’s interchangeable with SKF models for easy replacement.
