Product Description

1. Product Overview

The 71814ACD/DB single row angular contact ball bearing is supplied as a factory pre-matched back-to-back (DB) duplex set with 25° contact angle. The ultra-thin 718 series cross-section saves radial installation space, and back-to-back arrangement delivers excellent rigidity to bear radial load and bidirectional axial loads simultaneously.

It is widely used for precision machine tool spindles, testing instruments and high-speed precision automation rotary structures.
