Super Precision Angular Contact Ball Bearings 71910 CDTP/HCP4B

Super Precision Angular Contact Ball Bearings 71910 CDTP/HCP4B

The 71910 CDTP/HCP4B is a super precision angular contact ball bearing with a 50mm bore and 72mm outer diameter, crafted from high-quality chrome steel. Its compact 12mm width makes it suitable for tight spaces while maintaining robust performance.

This bearing handles radial loads up to 3038 lbf and reaches speeds of 22,000 RPM, thanks to its ceramic balls and phenolic cage. The 15° contact angle ensures smooth operation under angular loads, with optional preload for added stability.

Its open design allows easy lubrication, and it operates reliably in temperatures from -30°C to 110°C. The P4 tolerance class (equivalent to ABEC-7) guarantees exceptional precision for demanding applications.

Ideal for high-speed machinery like spindles or precision tools, this bearing is interchangeable with SKF models. Weighing just 0.12kg, it offers a lightweight yet durable solution for precision engineering needs.
