Super Precision Angular Contact Ball Bearings S7012 CEGA/HCP4A

Super Precision Angular Contact Ball Bearings S7012 CEGA/HCP4A

The S7012 CEGA/HCP4A is a super precision angular contact ball bearing with a 60mm bore and 95mm outer diameter, crafted from chrome steel for durability. Its 15° contact angle and ceramic balls ensure smooth operation under radial loads up to 3870 lbf.

This sealed unit comes pre-greased and spins at impressive speeds up to 36,000 RPM, making it ideal for high-performance applications. The phenolic cage adds stability while keeping weight low at just 0.4kg.

With a P4A tolerance class, it offers exceptional accuracy for precision machinery. The bearing works reliably in temperatures from -30°C to 110°C.

Designed for angular contact loads, it’s perfect for spindle assemblies or machine tools. Its universal matching capability allows flexible arrangement options (back-to-back, face-to-face, or tandem). Interchangeable with SKF bearings for easy replacement.
