Super Precision Angular Contact Ball Bearings 71915 CD/HCP4AQBCA

Super Precision Angular Contact Ball Bearings 71915 CD/HCP4AQBCA

The 71915 CD/HCP4AQBCA is a super precision angular contact ball bearing with a 75mm bore and 105mm outer diameter, crafted from durable chrome steel and ceramic balls. It handles radial loads up to 21510 lbf and spins smoothly at speeds up to 22000 RPM.

Its 15° contact angle and phenolic cage ensure stable performance under angular loads, while the extra-light preload (Class A) minimises friction. The open design allows for easy lubrication and maintenance.

This set includes four matched bearings (QBC arrangement), ideal for high-precision applications like machine tool spindles or aerospace components. It operates reliably in temperatures from -30°C to 110°C.

Weighing 1.21kg, it’s a robust choice for demanding environments. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for seamless replacements.
