Super Precision Angular Contact Ball Bearings 7210 ACD/P4ADBC

Super Precision Angular Contact Ball Bearings 7210 ACD/P4ADBC

The 7210 ACD/P4ADBC is a super precision angular contact ball bearing with a 50mm bore and 90mm outer diameter, crafted from durable chrome steel. Its 25° contact angle efficiently manages combined radial and axial loads.

This matched pair of bearings (DB arrangement) offers moderate preload for smooth operation, handling dynamic radial loads up to 15502 lbf. It spins exceptionally well at speeds up to 46000 RPM while maintaining precision.

The phenolic cage reduces friction and wear, enhancing longevity. Open design allows easy relubrication, suitable for temperatures from -30°C to 110°C.

Ideal for high-precision applications like machine tool spindles or robotics where accuracy and speed matter. Weighing 0.92kg, it’s a robust yet manageable solution for demanding setups.
