Super Precision Angular Contact Ball Bearings S7212 CDGB/P4A

Super Precision Angular Contact Ball Bearings S7212 CDGB/P4A

The S7212 CDGB/P4A is a super precision angular contact ball bearing with a 60mm bore and 110mm outer diameter, crafted from durable chrome steel. Its 15° contact angle efficiently manages combined radial and axial loads.

With a dynamic radial load capacity of 12870 lbf, it spins smoothly at speeds up to 32500 RPM. The phenolic cage and grease lubrication ensure quiet operation and long service life.

The sealed design keeps contaminants out while maintaining performance in temperatures from -30°C to 110°C. Its P4A tolerance class guarantees high precision for demanding applications.

Ideal for machine tools or high-speed spindles, this bearing comes in pairs for universal matching (back-to-back, face-to-face, or tandem arrangements). Weighing 0.82kg, it balances strength and precision.
