S71907 ACDTP/P4B Bearing Product Overview & Core Advantages
The S71907 ACDTP/P4B is a single-row angular contact ball bearing engineered for applications demanding high precision and superior rotational accuracy. Operating under the stringent P4 (ABEC-7) tolerance class, it is designed to handle significant axial loads in one direction and moderate radial loads simultaneously. Its compact design, featuring a 35 mm bore and a 10 mm width, makes it ideal for space-constrained, high-performance assemblies. The bearing comes preloaded and pre-lubricated, ensuring immediate operational readiness, high rigidity, and exceptional running accuracy right from installation.
