71932 CDGC/P4A Bearing Product Overview & Core Advantages
The 71932 CDGC/P4A is a single-row angular contact ball bearing designed for applications requiring high precision and moderate preload. Manufactured to P4A tolerance class, this bearing delivers exceptional dimensional accuracy and running precision. Its 15° contact angle is optimized to handle combined loads—significant radial loads with accompanying axial loads in one direction. The Universal Matchable (SU) designation allows for precise bearing arrangement in sets, enabling optimal stiffness and system performance in demanding applications.
