Super Precision Angular Contact Ball Bearings 7011 CBGA/P4A

Super Precision Angular Contact Ball Bearings 7011 CBGA/P4A

The 7011 CBGA/P4A is a super precision angular contact ball bearing with a 55mm bore and 90mm outer diameter, crafted from high-quality chrome steel. It features a 15° contact angle and comes in an open design for easy lubrication.

This bearing handles radial loads up to 3150 lbf and reaches speeds of 34,000 RPM, making it suitable for high-performance applications. Its phenolic cage ensures smooth operation and durability under stress.

Designed for angular contact loads, it’s available in matched sets for back-to-back, face-to-face, or tandem arrangements. The extra-light preload (Class A) enhances precision in demanding setups.

Ideal for machine tools or spindle drives, it operates in temperatures from -30°C to 110°C. Weighing 0.42kg, it’s lightweight yet robust, and interchangeable with SKF bearings for easy replacement.

Compliant with P4A tolerance standards, it offers reliable performance in precision engineering. The 26 balls, each 6.747mm in diameter, ensure even load distribution and smooth rotation.
