1207 K Bearing Product Overview & Core Advantages
The 1207 K is a metric double row angular contact ball bearing engineered for applications requiring high rigidity and precise operation. Featuring a 1:12 tapered bore for secure shaft mounting, this bearing excels at handling combined radial and axial loads simultaneously. Its compact design with a 17mm width makes it ideal for space-constrained, high-reliability applications. Manufactured from chrome steel and equipped with a nylon cage, it delivers excellent performance within a temperature range of -30° to 110°C.

| K | Denotes a tapered bore with a 1:12 ratio, enabling precise interference fit on the shaft for enhanced stability. |
1207 K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides superior stiffness, enabling it to support significant radial dynamic loads (4275 lbf) and axial loads from both directions.
- Precision Tapered Bore: The 1:12 tapered bore ensures a tight, secure fit on a tapered shaft adapter, minimizing inner ring creep and maintaining precise alignment under high loads.
- Optimized for Speed: The lightweight nylon cage reduces centrifugal forces, contributing to a high limiting speed of 13,000 rpm and smooth operation.
- Ready-to-Use Lubrication: The bearing is pre-lubricated, ensuring immediate operational readiness and reducing initial maintenance requirements.
- Standard Internal Clearance: Features a CN (normal) group radial internal clearance, making it suitable for a wide range of common operating conditions.
1207 K Bearing Typical Application Areas
This double row angular contact ball bearing is ideally suited for:
- Electric Motors and Gearboxes
- Agricultural Machinery and implements
- Material Handling Equipment such as conveyor pulleys
- Industrial Fans and blowers
- Various machinery requiring a robust bearing with a tapered bore for secure mounting
