Super Precision Angular Contact Ball Bearings S71910 ACDGC/P4A

Super Precision Angular Contact Ball Bearings S71910 ACDGC/P4A

The S71910 ACDGC/P4A is a super precision angular contact ball bearing with a 50mm bore and 72mm outer diameter, crafted from durable chrome steel. It features a 25° contact angle and comes sealed for protection, with a phenolic cage for smooth operation.

This bearing handles radial loads up to 2858 lbf and spins at speeds up to 34,000 RPM, making it suitable for high-performance applications. Its moderate preload (Class C) ensures stable operation under angular contact loads.

The sealed design keeps lubrication in and contaminants out, while the P4A tolerance class guarantees precision. It’s versatile, working in temperatures from -30°C to 110°C.

Ideal for machine tools or high-speed spindles, this bearing is interchangeable with SKF models. Weighing just 0.14kg, it’s lightweight yet robust. Universal matching allows use in back-to-back, face-to-face, or tandem arrangements.
