Super Precision Angular Contact Ball Bearings S71912 ACB/P4ADGB

Super Precision Angular Contact Ball Bearings S71912 ACB/P4ADGB

The S71912 ACB/P4ADGB is a super precision angular contact ball bearing measuring 60mm by 85mm by 26mm, crafted from durable chrome steel. It features a 25° contact angle and comes sealed for protection, with a phenolic cage for smooth operation.

This bearing handles radial loads up to 3578 lbf and spins at speeds up to 36,000 RPM, making it suitable for high-performance applications. Its light preload (Class B) ensures precise movement with minimal friction.

Designed for universal matching, it works in back-to-back, face-to-face, or tandem arrangements. Ideal for machine tools or precision equipment where accuracy is key.

Weighing 0.41kg, it’s grease-lubricated and operates in temperatures from -30°C to 110°C. Compliant with P4A tolerance standards for reliable performance.

Interchangeable with SKF bearings, it’s a practical choice for replacements or upgrades. The set includes two matched bearings for versatile use.
