Super Precision Angular Contact Ball Bearings 7220 CD/P4ATBTA

Super Precision Angular Contact Ball Bearings 7220 CD/P4ATBTA

The 7220 CD/P4ATBTA is a super precision angular contact ball bearing with a 100mm bore and 180mm outer diameter, crafted from high-quality chrome steel. It measures 100mm×180mm×102mm and comes in a set of three matched bearings for balanced performance.

This bearing handles radial loads up to 76050 lbf and spins smoothly at speeds up to 16250 RPM, thanks to its 15° contact angle and phenolic cage. Its extra-light preload ensures minimal friction during operation.

The open design allows for easy lubrication, while the P4A tolerance class guarantees tight precision. It operates reliably in temperatures from -30°C to 110°C, making it suitable for demanding environments.

Ideal for high-precision applications like machine tool spindles or industrial gearboxes, where accuracy and durability are key. Weighing 9.73kg, it’s a robust choice for heavy-duty use. Interchangeable with SKF bearings for convenient replacements.
