Super Precision Angular Contact Ball Bearings S7012 ACEGA/P4A

Super Precision Angular Contact Ball Bearings S7012 ACEGA/P4A

The S7012 ACEGA/P4A is a super precision angular contact ball bearing with a 60mm bore and 95mm outer diameter, crafted from durable chrome steel. It features a 25° contact angle and comes sealed for protection, with grease lubrication for smooth operation.

This bearing handles radial loads up to 3668 lbf and spins at speeds up to 31,000 RPM, making it suitable for high-performance applications. Its phenolic cage ensures stability and reduces friction during use.

The P4A tolerance class guarantees exceptional precision, while the extra light preload (Class A) enhances performance in sensitive setups. It works in temperatures from -30°C to 110°C and weighs just 0.43kg.

Ideal for machine tools or high-speed spindles, this model is interchangeable with SKF bearings. It can be arranged back-to-back, face-to-face, or tandem, offering flexibility in complex assemblies.
