Super Precision Angular Contact Ball Bearings S7011 FE/HCP4ADBA

Super Precision Angular Contact Ball Bearings S7011 FE/HCP4ADBA

The S7011 FE/HCP4ADBA is a super precision angular contact ball bearing with a 55mm bore and 90mm outer diameter, crafted from high-quality chrome steel and ceramic balls. It handles radial loads up to 6075 lbf and spins at speeds up to 46,000 RPM, making it suitable for high-performance applications.

Its sealed design and phenolic cage ensure smooth operation with minimal maintenance, while the extra-light preload (Class A) enhances precision. The bearing operates efficiently in temperatures from -30°C to 110°C.

This matched set of two bearings (DB arrangement) is ideal for machinery requiring high accuracy, such as CNC spindles or medical equipment. The 18° contact angle provides excellent load distribution.

Weighing 0.75kg, it’s a robust yet lightweight solution for demanding environments. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for easy replacement.
