Super Precision Angular Contact Ball Bearings 7030 ACD/P4ATBTB

Super Precision Angular Contact Ball Bearings 7030 ACD/P4ATBTB

The 7030 ACD/P4ATBTB is a super precision angular contact ball bearing with a 150mm bore and 225mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 78975 lbf and spins smoothly at speeds up to 11000 RPM.

Its 25° contact angle and matched set of three bearings (arranged > TBT) provide excellent stability under angular loads. The phenolic cage ensures quiet operation and long service life.

Designed for light preload (Class B), this bearing suits high-precision applications like machine tool spindles or high-speed robotics. It operates reliably in temperatures from -30°C to 110°C.

Weighing 12.5kg, this P4A-tolerance bearing is interchangeable with SKF models, making it a practical choice for precision engineering needs. The open design allows for easy lubrication when required.
