71810 ACD/P4 Bearing Product Overview & Core Advantages
The 71810 ACD/P4 is a single-row angular contact ball bearing designed for applications requiring high precision and superior rigidity. Engineered to P4 (ABEC-7) tolerance class, this bearing excels at handling combined loads—simultaneously supporting significant radial and axial loads in one direction. Its compact design, featuring a 7mm width, makes it ideal for space-constrained, high-performance assemblies. The phenolic cage and optimized 25° contact angle contribute to exceptional high-speed capabilities and smooth operation, making it a reliable choice for demanding industrial environments.
