7313 BEGAM Bearing Product Overview & Core Advantages
The 7313 BEGAM is a single row angular contact ball bearing engineered for high-precision applications requiring superior performance under combined loads. This metric bearing features a 40° contact angle and P6 (ABEC-3) tolerance class, making it ideal for applications demanding high rotational accuracy and rigidity. Its optimized internal geometry enables it to efficiently handle significant radial loads and axial loads in one direction simultaneously. The brass cage construction ensures reliable operation at high speeds, while the open design allows for customized lubrication solutions tailored to specific operational requirements.
