Super Precision Angular Contact Ball Bearings 71913 FE/HCP4ALDT

Super Precision Angular Contact Ball Bearings 71913 FE/HCP4ALDT

The 71913 FE/HCP4ALDT is a super precision angular contact ball bearing with a 65mm bore and 90mm outer diameter, crafted from high-quality chrome steel and ceramic balls. It handles radial loads up to 5962 lbf and reaches speeds of 36,000 RPM, making it suitable for high-performance applications.

Its 18° contact angle and matched arrangement of two bearings ensure stability under angular loads. The phenolic cage adds durability while keeping the weight low at just 0.34kg.

This bearing is lubricated for smooth operation and works in temperatures from -30°C to 110°C. Its P4A tolerance class guarantees precision, ideal for CNC spindles or high-speed machinery.

Interchangeable with SKF bearings, it offers a reliable replacement option. The open design allows for easy maintenance, while the ceramic balls reduce friction for longer service life.
