7208 ACCBM Bearing Product Overview & Core Advantages
The 7208 ACCBM 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 25° contact angle for optimal thrust capacity. Manufactured to P6 (ABEC-3) tolerance class, it delivers exceptional running accuracy and dimensional stability. The open design with brass cage ensures superior high-speed performance up to 16,000 rpm, making it ideal for precision machinery where rigidity and operational reliability are critical.
