Super Precision Angular Contact Ball Bearings 7209 ACD/HCP4ATBTB

Super Precision Angular Contact Ball Bearings 7209 ACD/HCP4ATBTB

The 7209 ACD/HCP4ATBTB is a super precision angular contact ball bearing with a 45mm bore and 85mm outer diameter, designed for high-speed applications. Its 25° contact angle and ceramic balls ensure smooth operation under radial loads up to 19890 lbf.

The matched set of three bearings (arranged TBT) offers stability, while the phenolic cage reduces friction. It spins at speeds up to 41000 RPM and handles temperatures from -30°C to 110°C.

With a P4A tolerance class, this bearing is ideal for precision machinery like spindles or CNC equipment. Its open design allows easy lubrication, and the chrome steel rings provide durability.

Weighing 1.02kg, it’s a robust yet lightweight choice for demanding industrial applications. Interchangeable with SKF bearings, it simplifies replacements.
