70/950 AMB Bearing Product Overview & Core Advantages
The 70/950 AMB is a single row angular contact ball bearing designed for precision applications requiring high load capacity and dimensional stability. This metric series bearing features a 950 mm bore and is manufactured to P6 (ABEC-3) tolerance class, ensuring exceptional running accuracy. Its optimized 40° contact angle provides superior axial load carrying capacity in one direction while maintaining excellent radial load performance. The bearing comes pre-lubricated and operates effectively within a temperature range of -30° to 110°C, making it suitable for demanding industrial environments.
