Super Precision Angular Contact Ball Bearings S7007 ACD/P4AQBCB

Super Precision Angular Contact Ball Bearings S7007 ACD/P4AQBCB

The S7007 ACD/P4AQBCB is a super precision angular contact ball bearing with a 35mm bore and 62mm outer diameter, crafted from durable chrome steel. It handles radial loads up to 8932 lbf and spins smoothly at speeds up to 41,000 RPM.

Its sealed design keeps grease in and contaminants out, while the phenolic cage ensures quiet operation. The 25° contact angle provides stability under angular loads, and the light preload (Class B) enhances precision.

This set includes four matched bearings (QBC arrangement), ideal for high-accuracy applications like machine tool spindles or robotics. It operates reliably in temperatures from -30°C to 110°C.

Weighing 0.62kg, it’s a robust yet manageable choice for precision engineering. Compliant with P4A tolerance standards, it’s interchangeable with SKF bearings for easy replacements.
