1212KTN Bearing Product Overview & Core Advantages
The 1212KTN is a double row angular contact ball bearing designed for applications requiring high precision and robust performance. This metric bearing features a tapered bore (1:12) for secure shaft mounting and is constructed from high-grade chrome steel for exceptional durability. Its primary advantage lies in its ability to accommodate significant radial loads while maintaining operational stability. The optimized internal geometry and nylon cage contribute to smooth operation and reduced friction, making it ideal for demanding industrial environments where reliability is paramount.

1212KTN Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior stiffness and enables the bearing to support substantial radial dynamic loads (rated at 7020 lbf). This makes it exceptionally resistant to deformation under heavy operational stresses.
- Optimized High-Speed Performance: The lightweight nylon cage (TN) ensures excellent guidance of the balls with minimal friction, contributing to a high limiting speed of 8,000 rpm. This is critical for applications requiring rapid rotation.
- Precision Tapered Bore: The K-designation tapered bore allows for precise axial positioning and a tight, interference fit on the shaft, eliminating creep and enhancing overall system stability.
- Standard Internal Clearance & Lubrication: Supplied with CN group radial internal clearance and pre-lubricated, the bearing is ready for immediate installation and offers reliable performance across a wide temperature range from -30°C to 110°C.
1212KTN Bearing Typical Application Areas
This bearing is engineered for high-performance machinery and is commonly specified in:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
- Various industrial applications requiring a robust double row ball bearing with a tapered bore.
