Super Precision Angular Contact Ball Bearings S71909 CD/P4ATBTC

Super Precision Angular Contact Ball Bearings S71909 CD/P4ATBTC

The S71909 CD/P4ATBTC is a super precision angular contact ball bearing with a 45mm bore and 68mm outer diameter, crafted from durable chrome steel. It features a 15° contact angle and comes in a matched set of three bearings for balanced performance.

Designed for angular contact loads, it handles dynamic radial loads up to 6322 lbf and spins smoothly at speeds up to 46,000 RPM. The phenolic cage and sealed design ensure reliable operation with grease lubrication.

Its moderate preload (Class C) and P4A tolerance class make it ideal for high-precision applications. The bearing performs well in temperatures from -30°C to 110°C.

This model is interchangeable with SKF bearings, offering a practical replacement option. Suitable for machine tools or spindle assemblies where precision and stability are key. Weighing 0.4kg, it’s a robust yet manageable choice for demanding setups.
