1207K Bearing Product Overview & Core Advantages
The 1207K double row angular contact ball bearing is a precision bearing engineered for applications requiring high rigidity and reliable performance under combined loading conditions. Featuring a tapered bore design (1:12) and manufactured from high-grade chrome steel, this bearing excels at simultaneously handling radial loads while maintaining dimensional stability. Its compact double-row construction provides superior stiffness compared to single-row designs, making it ideal for high-precision machinery where minimal deflection is critical. Pre-lubricated and featuring a nylon cage, it offers smooth operation and is ready for immediate installation.
1207K Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1207 | Standard bearing designation indicating bore diameter (35 mm) and size series. |
| K | Denotes a tapered bore with a 1:12 ratio, enabling precise radial clearance adjustment via mounting on an adapter sleeve. |
1207K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact ball bearing design provides significantly increased stiffness and enables the bearing to support substantial combined loads (radial and axial) from both directions.
- Precision Tapered Bore: The K-suffix tapered bore (1:12) allows for precise control over internal clearance during installation, ensuring optimal preload and operational accuracy.
- Optimized High-Speed Performance: The lightweight nylon cage minimizes centrifugal forces, reduces friction, and contributes to a high limiting speed of 13,000 rpm, making it suitable for high-speed applications.
- Pre-Lubricated & Ready-to-Use: Factory-applied lubrication ensures immediate operation, reduces initial setup time, and provides reliable performance within the specified temperature range of -30°C to 110°C.
1207K Bearing Typical Application Areas
- Electric Motors and Generators (particularly where a tapered shaft is used)
- Precision Machine Tool Spindles
- Gearboxes and Power Transmission Systems
- Pumps and Compressors
- Agricultural and Material Handling Machinery
