Super Precision Angular Contact Ball Bearings 71808 ACDGA/P4

Super Precision Angular Contact Ball Bearings 71808 ACDGA/P4

The 71808 ACDGA/P4 is a super precision angular contact ball bearing with a 40mm bore and 52mm outer diameter, crafted from high-quality chrome steel. Its slim 7mm width makes it suitable for compact spaces while maintaining robust performance.

Designed for angular contact loads, it handles radial loads up to 1010 lbf and spins smoothly at speeds up to 56,000 RPM. The phenolic cage ensures durability and reduces friction during high-speed operations.

With a 25° contact angle and extra light preload, it offers precise movement and low noise. Ideal for applications like machine tool spindles or high-speed motors where accuracy is key.

This bearing is interchangeable with SKF models and comes lubricated for immediate use. Its lightweight design (0.031kg) and universal matching capability add to its versatility.
