Super Precision Angular Contact Ball Bearings S7011 ACEGA/P4A

Super Precision Angular Contact Ball Bearings S7011 ACEGA/P4A

The S7011 ACEGA/P4A is a super precision angular contact bearing with a 55mm bore and 90mm outer diameter, crafted from high-grade chrome steel. It features a 25° contact angle and comes sealed for protection, with an extra-light preload for smooth operation.

This bearing handles dynamic radial loads up to 3578 lbf and spins at speeds up to 34,000 RPM, thanks to its phenolic cage and grease lubrication. It performs reliably in temperatures from -30°C to 110°C.

Its P4A tolerance class ensures exceptional accuracy, while the 24 chrome steel balls provide balanced performance. The bearing is part of a universal matching set, suitable for back-to-back, face-to-face, or tandem arrangements.

Ideal for high-precision applications like machine tools or spindles, where low vibration and tight tolerances are crucial. Weighing 0.4kg, it’s a robust yet lightweight choice for demanding setups.
