Super Precision Angular Contact Ball Bearings 7030 ACD/P4ADGA

Super Precision Angular Contact Ball Bearings 7030 ACD/P4ADGA

The 7030 ACD/P4ADGA is a super precision angular contact ball bearing with a 150mm bore and 225mm outer diameter, crafted from durable chrome steel. Its 25° contact angle and extra light preload ensure smooth operation under radial loads up to 59625 lbf.

This open-design bearing reaches speeds of 11000 RPM and works in temperatures from -30°C to 110°C. The phenolic cage reduces friction, while the universal matching allows flexible arrangements like back-to-back or face-to-face.

Ideal for high-precision applications like machine tools or spindles, it comes in a matched set of two bearings. Weighing 8.35kg, it’s robust yet designed for accuracy. Compliant with P4A tolerance standards for reliable performance.

Its interchangeable design with SKF bearings makes it a practical choice for replacements. The lubricated setup ensures easy maintenance and long service life.
