Super Precision Angular Contact Ball Bearings 7011 CEGA/HCP4AL1

Super Precision Angular Contact Ball Bearings 7011 CEGA/HCP4AL1

The 7011 CEGA/HCP4AL1 is a super precision angular contact ball bearing measuring 55mm by 90mm by 18mm, crafted from chrome steel with ceramic balls for enhanced performance. It handles radial loads up to 3780 lbf and reaches speeds of 34,000 RPM, making it suitable for high-speed applications.

Its 15° contact angle and phenolic cage ensure smooth operation under angular loads. The extra light preload (Class A) minimises friction, while the open design allows for easy lubrication.

This bearing is ideal for precision machinery like CNC spindles or high-speed motors, where accuracy and durability are key. It operates in temperatures from -30°C to 110°C and is interchangeable with SKF models.

Weighing 0.36kg, it’s part of a universal matching set (back-to-back, face-to-face, or tandem), offering flexibility in assembly. Compliant with P4A tolerance standards for reliable performance.
