Super Precision Angular Contact Ball Bearings S7011 FE/HCPA9ADBA

Super Precision Angular Contact Ball Bearings S7011 FE/HCPA9ADBA

The S7011 FE/HCPA9ADBA is a super precision angular contact ball bearing with a 55mm bore and 90mm outer diameter, crafted from durable chrome steel and ceramic balls. It handles radial loads up to 6075 lbf and spins smoothly at high speeds up to 46,000 RPM.

Its sealed design keeps grease in and contaminants out, while the phenolic cage ensures quiet, long-lasting performance. The 18° contact angle and extra-light preload make it ideal for precise applications.

This matched set of two bearings (DB arrangement) is perfect for high-speed machinery like spindles or CNC tools. It operates reliably in temperatures from -30°C to 110°C.

Weighing 0.75kg, it’s a robust yet lightweight choice for demanding environments. Compliant with precision standards, it’s interchangeable with SKF bearings for easy replacements.
