Super Precision Angular Contact Ball Bearings S7011 CE/P4ADBB

Super Precision Angular Contact Ball Bearings S7011 CE/P4ADBB

The S7011 CE/P4ADBB is a super precision angular contact ball bearing with a 55mm bore and 90mm outer diameter, crafted from durable chrome steel. It features a 15° contact angle and comes sealed for protection, with two bearings matched in a back-to-back arrangement.

This bearing handles radial loads up to 6210 lbf and spins smoothly at high speeds, reaching up to 46,000 RPM. Its phenolic cage ensures quiet operation, while the light preload (Class B) enhances stability in precise applications.

The sealed design keeps grease in and contaminants out, making it low-maintenance. Ideal for machine tools or high-speed spindles where accuracy and reliability are key.

Weighing 0.81kg, it’s robust yet manageable for its size. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for easy replacements. Suitable for temperatures from -30°C to 110°C.
