Super Precision Angular Contact Ball Bearings S7012 ACE/P4A

Super Precision Angular Contact Ball Bearings S7012 ACE/P4A

The S7012 ACE/P4A is a super precision angular contact ball bearing with a 60mm bore and 95mm outer diameter, crafted from durable chrome steel. Its 25° contact angle efficiently handles both radial and axial loads, making it versatile for high-performance applications.

This sealed bearing comes pre-lubricated and can reach speeds up to 18,000 RPM, with a temperature range of -30°C to 110°C. The phenolic cage ensures smooth operation and reduces friction during high-speed rotation.

With a P4 tolerance class (equivalent to ABEC-7), it offers exceptional accuracy for demanding machinery. The bearing is interchangeable with SKF models, providing a reliable replacement option.

Ideal for precision equipment like CNC spindles or high-speed motors, where both speed and accuracy are crucial. Weighing 0.43kg, it balances lightweight design with robust performance.
