Super Precision Angular Contact Ball Bearings 7210 ACD/P4ADFB

Super Precision Angular Contact Ball Bearings 7210 ACD/P4ADFB

The 7210 ACD/P4ADFB is a super precision angular contact ball bearing with a 50mm bore and 90mm outer diameter, crafted from high-quality chrome steel. It’s designed for angular contact loads and comes in a matched set of two bearings arranged back-to-back (DF).

This bearing handles radial loads up to 15502 lbf and operates smoothly at speeds up to 46,000 RPM. Its light preload (Class B) ensures quiet and precise performance, ideal for high-accuracy applications.

The open seal design allows for easy lubrication, while the phenolic cage enhances durability. With a 25° contact angle, it’s well-suited for combined radial and axial loads.

Perfect for precision machinery like CNC spindles or high-speed tooling, where tight tolerances (P4A) are required. It works in temperatures from -30°C to 110°C and weighs just 0.92kg. Interchangeable with SKF bearings for easy replacement.
