Super Precision Angular Contact Ball Bearings 71807 ACDGA/P4

Super Precision Angular Contact Ball Bearings 71807 ACDGA/P4

The 71807 ACDGA/P4 is a super precision angular contact ball bearing with a 35mm bore and 47mm outer diameter, crafted from durable chrome steel. Its compact 7mm width makes it suitable for tight spaces while handling radial loads up to 981 lbf.

With a 25° contact angle, it efficiently manages combined loads and spins smoothly at speeds up to 56,000 RPM. The phenolic cage ensures quiet operation and reduced friction.

This open-design bearing comes pre-lubricated and operates in temperatures from -30°C to 110°C. Its P4 tolerance class guarantees high precision for demanding applications.

Ideal for precision machinery like spindles or CNC tools, it can be paired in back-to-back, face-to-face, or tandem arrangements. Weighing just 0.028kg, it offers excellent performance without adding bulk.
