7313 BECBF Bearing Product Overview & Core Advantages
The 7313 BECBF is a single row angular contact ball bearing designed for applications requiring high precision and reliable performance under combined loads. Engineered to accommodate significant axial loads in one direction alongside radial loads, this bearing features a 40° contact angle for optimal load distribution. Manufactured to P6 (ABEC-3) tolerance class, it delivers exceptional running accuracy and dimensional stability. The bearing comes pre-lubricated and operates effectively within a temperature range of -30° to 110°C, making it suitable for demanding industrial environments where consistent performance and high rigidity are critical.
