S71907 CD/P4A Bearing Product Overview & Core Advantages
The S71907 CD/P4A is a single-row angular contact ball bearing engineered for applications demanding high precision and superior running accuracy. Positioned in the P4 (ABEC-7) tolerance class, it is designed to handle combined loads, primarily thrust loads in one direction, with a 15° contact angle that provides an excellent balance between radial and axial load capacity. Its compact design, featuring a 35 mm bore and a 10 mm width, makes it ideal for space-constrained, high-speed applications such as precision spindles. The bearing comes preloaded and pre-lubricated for immediate use, ensuring high operational reliability and simplified installation.
