Super Precision Angular Contact Ball Bearings S71915 CE/HCP4AQBCA

Super Precision Angular Contact Ball Bearings S71915 CE/HCP4AQBCA

The S71915 CE/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 13320 lbf and spins smoothly at speeds up to 28000 RPM, thanks to its phenolic cage and grease lubrication.

Its sealed design keeps contaminants out, while the 15° contact angle ensures stable performance under angular loads. The extra light preload (Class A) reduces friction, making it ideal for high-speed applications.

This set includes four matched bearings (QBC arrangement), offering consistent performance in demanding setups. Perfect for precision machinery like CNC spindles or high-speed motors where accuracy and speed matter.

Weighing 1.18kg, it operates reliably in temperatures from -30°C to 110°C. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for easy replacements.
