Super Precision Angular Contact Ball Bearings 71913 FE/HCPA9ADBA

Super Precision Angular Contact Ball Bearings 71913 FE/HCPA9ADBA

The 71913 FE/HCPA9ADBA is a super precision angular contact ball bearing with a 65mm bore and 90mm outer diameter, crafted from chrome steel for durability. It features a 18° contact angle and comes in a matched pair (DB arrangement) for balanced performance.

With a dynamic radial load capacity of 5962 lbf, it spins smoothly at speeds up to 36,000 RPM. The ceramic balls and phenolic cage reduce friction, making it ideal for high-speed applications.

Its open design allows easy lubrication, while the extra light preload (Class A) ensures precise operation. The bearing works well in temperatures from -30°C to 110°C.

This model is interchangeable with SKF bearings, offering a reliable option for replacements. Perfect for precision machinery like spindles or CNC equipment where accuracy and speed are key.

Weighing 0.34kg, it’s lightweight yet robust. The PA9A tolerance class guarantees high precision for demanding tasks.
