71916 ACD/P4A Bearing Product Overview & Core Advantages
The 71916 ACD/P4A is a single-row angular contact ball bearing designed for applications requiring high precision and superior rotational accuracy. Engineered to a P4 (ABEC-7) tolerance class, it is optimized to accommodate combined loads, primarily thrust loads in one direction, while also supporting significant radial loads. Its compact cross-section, defined by a 16mm width, makes it ideal for space-constrained, high-performance assemblies. The bearing is preloaded and comes pre-lubricated, ensuring immediate operational readiness and contributing to its high rigidity and stable running characteristics.
