Super Precision Angular Contact Ball Bearings 71814 CD/HCP4

Super Precision Angular Contact Ball Bearings 71814 CD/HCP4

The 71814 CD/HCP4 is a super precision angular contact ball bearing with a 70mm bore and 90mm outer diameter, crafted from high-quality chrome steel. Its compact 10mm width makes it suitable for tight spaces, while the ceramic balls enhance durability.

This bearing handles radial loads up to 3105 lbf and spins smoothly at speeds up to 26,000 RPM, thanks to its phenolic cage. The 15° contact angle ensures efficient load distribution for angular contact applications.

Its open design allows easy lubrication, and the P4 tolerance class guarantees high precision. Ideal for CNC spindles or high-speed machinery where accuracy is key.

Weighing just 0.12kg, it’s lightweight yet robust. Compatible with SKF bearings, it’s a reliable choice for replacements or upgrades. Works well in temperatures from -30°C to 110°C.
