Super Precision Angular Contact Ball Bearings 7205 CD/P4ADGB

Super Precision Angular Contact Ball Bearings 7205 CD/P4ADGB

The 7205 CD/P4ADGB is a super precision angular contact ball bearing with a 25mm bore and 52mm outer diameter, crafted from high-quality chrome steel. It features a 15° contact angle and comes in a universal matching set of two bearings.

This model handles dynamic radial loads up to 4972 lbf and operates smoothly at speeds up to 100,500 RPM. Its phenolic cage ensures durability while the open design allows for easy lubrication.

The bearing is preloaded lightly (Class B) for precise performance, making it ideal for high-speed applications like machine tool spindles or precision instruments. It works in temperatures from -30°C to 110°C.

Weighing just 0.26kg, it’s a lightweight yet robust choice. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for reliable replacements. Suitable for back-to-back, face-to-face, or tandem arrangements.
