1208K Bearing Product Overview & Core Advantages
The 1208K metric double row angular contact ball bearing is engineered for applications requiring high radial load capacity and precise operation. Featuring a tapered bore (1:12) for secure shaft mounting, this bearing delivers exceptional rigidity and rotational accuracy. Its double row design provides superior load-carrying capacity compared to single row bearings, making it ideal for compact spaces where high performance is critical. Manufactured from chrome steel and equipped with a nylon cage, it offers reliable operation across a wide temperature range from -30° to 110°C.

1208K Bearing Structural Features & Performance Benefits
Double Row Design: The dual raceway configuration provides enhanced rigidity and stability, effectively handling substantial radial loads while maintaining precise alignment.
Optimized Cage Design: The nylon cage ensures smooth operation at high speeds (up to 11,000 rpm) with reduced friction and excellent guidance for the ball complement.
Tapered Bore Advantage: The 1:12 tapered bore enables precise axial positioning and secure interference fit when mounted with adapter sleeves, eliminating clearance and enhancing system stability.
Premium Material Construction: Manufactured from chrome steel for both rings and balls, delivering exceptional durability, wear resistance, and consistent performance under demanding conditions.
Standard Radial Clearance: CN clearance group provides optimal internal fit for most industrial applications, balancing thermal expansion and operational precision.
