Super Precision Angular Contact Ball Bearings 7048 ACD/P4ADBA

Super Precision Angular Contact Ball Bearings 7048 ACD/P4ADBA

The 7048 ACD/P4ADBA is a super precision angular contact ball bearing with a 240mm bore and 360mm outer diameter, designed for high-performance applications. Its 25° contact angle and matched arrangement of two bearings ensure smooth handling of combined radial and axial loads.

Made from durable chrome steel with a phenolic cage, it supports dynamic radial loads up to 118575 lbf and speeds up to 7500 RPM. The extra-light preload (Class A) enhances precision and reduces friction during operation.

Its open design allows easy lubrication, while the P4A tolerance class guarantees tight manufacturing standards. Suitable for temperatures from -30°C to 110°C, it’s ideal for machine tools or high-speed spindles.

Weighing 34.2kg, this bearing is robust yet precision-engineered for demanding environments. Interchangeable with SKF bearings, it’s a reliable choice for industrial replacements.
