Super Precision Angular Contact Ball Bearings 7030 CD/P4ADBB

Super Precision Angular Contact Ball Bearings 7030 CD/P4ADBB

The 7030 CD/P4ADBB is a super precision angular contact ball bearing with a 150mm bore and 225mm outer diameter, crafted from high-quality chrome steel. It handles radial loads up to 63225 lbf and operates smoothly at speeds up to 11000 RPM.

Its 15° contact angle and matched arrangement of two bearings provide excellent stability under angular loads. The phenolic cage ensures durability and quiet operation, even at high speeds.

This bearing is preloaded for light use (Class B) and works well in temperatures from -30°C to 110°C. Its open design allows for easy lubrication and maintenance.

Ideal for precision applications like machine tool spindles or high-speed robotics, where accuracy and reliability are key. Weighing 8.35kg, it’s robust yet manageable for its size. Compliant with P4A tolerance standards for consistent performance.

Interchangeable with SKF bearings, making it a practical choice for replacements or upgrades. The lack of universal matching means it’s best used in pairs as designed.
