Super Precision Angular Contact Ball Bearings S7011 CEGA/HCPA9A

Super Precision Angular Contact Ball Bearings S7011 CEGA/HCPA9A

The S7011 CEGA/HCPA9A is a super precision angular contact ball bearing with a 55mm bore and 90mm outer diameter, crafted from durable chrome steel. Its compact 18mm width makes it suitable for tight spaces while handling radial loads up to 3780 lbf.

Featuring a 15° contact angle and ceramic balls, it spins smoothly at high speeds up to 46,000 RPM. The sealed design keeps grease in and contaminants out, ensuring long-lasting performance in temperatures from -30°C to 110°C.

This bearing comes with an extra light preload (Class A) for precise operation, ideal for applications like machine tool spindles or high-speed robotics. Its phenolic cage provides stability under demanding conditions.

Weighing 0.37kg, it’s available as a single unit or in matched sets for back-to-back, face-to-face, or tandem arrangements. Compliant with precision standards, it’s interchangeable with SKF bearings for easy replacement.
