7205 BECBPH Bearing Product Overview & Core Advantages
The 7205 BECBPH is a single row angular contact ball bearing engineered for high-precision applications requiring superior performance. This metric bearing features a 25 mm bore and is designed to accommodate combined loads, particularly excelling under high axial loads in one direction due to its specific 40° contact angle. Manufactured to P6 (ABEC-3) tolerance class, it ensures precise running accuracy and high operational reliability. Its compact design with a 15 mm width makes it ideal for space-constrained assemblies in demanding industrial environments.
