1312 K Bearing Product Overview & Core Advantages
The 1312 K metric double row angular contact ball bearing is engineered for applications requiring high radial load capacity and rigid shaft support. Featuring a 1:12 tapered bore for precise interference fit adjustments, this bearing delivers exceptional rotational accuracy and stability. Its double row design provides superior stiffness and load distribution compared to single row alternatives, making it ideal for precision machinery operating under significant radial forces. The open construction with CN radial internal clearance ensures optimal performance across various operating conditions.

1312 K Bearing Structural Features & Performance Benefits
Enhanced Rigidity & Load Capacity: The double row ball bearing configuration provides significantly higher radial stiffness than single row designs, with a dynamic load rating of 13,162 lbf and static load rating of 4,950 lbf. This makes it capable of handling substantial radial loads while maintaining precise shaft positioning.
Tapered Bore Advantage: The 1:12 tapered bore allows for precise axial displacement during mounting, enabling optimal internal clearance control and preload adjustment for specific application requirements.
High-Speed Capability: Utilizing a nylon cage and optimized internal geometry, this bearing achieves a limiting speed of 6,300 rpm, suitable for various industrial applications requiring rapid rotation.
Material Excellence: Constructed from chrome steel for both rings and balls, the bearing offers excellent wear resistance and durability across the operating temperature range of -30°C to 110°C.
