Super Precision Angular Contact Ball Bearings 7048 ACD/P4ADBC

Super Precision Angular Contact Ball Bearings 7048 ACD/P4ADBC

The 7048 ACD/P4ADBC is a super precision angular contact ball bearing with a 240mm bore and 360mm outer diameter, crafted from durable chrome steel. Its 25° contact angle and matched pair arrangement (DB) offer excellent load distribution.

This bearing handles dynamic radial loads up to 118,575 lbf and spins smoothly at 7500 RPM. The phenolic cage ensures quiet operation, while moderate preload (Class C) provides stable performance.

Its open design allows easy relubrication, ideal for high-speed applications. Suitable for machine tools or precision spindles where accuracy is crucial.

Weighing 34.2kg, this P4A-class bearing operates in temperatures from -30°C to 110°C. Interchangeable with SKF equivalents for easy replacement.
