7318 BECBY Bearing Product Overview & Core Advantages
The 7318 BECBY is a single row angular contact ball bearing designed for applications requiring high precision and superior performance. This metric bearing features a 40° contact angle, enabling it to effectively handle combined loads—both radial and significant axial loads in one direction. Manufactured to P6 (ABEC-3) tolerance class, it delivers exceptional running accuracy, making it ideal for high-speed and high-rigidity applications. The bearing comes pre-lubricated and is constructed from durable chrome steel for extended service life.
