Super Precision Angular Contact Ball Bearings S7001 ACEGC/P4A

Super Precision Angular Contact Ball Bearings S7001 ACEGC/P4A

The S7001 ACEGC/P4A is a super precision angular contact ball bearing with a 12mm bore and 28mm outer diameter, crafted from durable chrome steel. It handles moderate radial loads up to 691 lbf and spins smoothly at speeds up to 95,000 RPM.

Its sealed design keeps grease in place, reducing maintenance needs, while the phenolic cage ensures quiet operation. The 25° contact angle makes it ideal for combined radial and thrust loads.

This bearing is suitable for high-precision applications like machine tool spindles or dental equipment. It operates reliably in temperatures from -30°C to 110°C and comes pre-lubricated for easy installation.

Weighing just 0.021kg, it’s lightweight yet robust. The P4A tolerance class ensures exceptional accuracy, and it can be paired in back-to-back, face-to-face, or tandem arrangements for versatile use.
