1307 K Bearing Product Overview & Core Advantages
The 1307 K is a double row angular contact ball bearing designed for applications requiring high radial load capacity and precise operation. Featuring a metric tapered bore (1:12), this bearing offers exceptional rigidity and stable rotational characteristics. Its double row ball construction enables it to handle significant combined loads while maintaining dimensional stability. Manufactured with chrome steel components and a nylon cage, it delivers reliable performance in demanding industrial environments. The bearing comes pre-lubricated and is suitable for moderate speed applications up to 11,000 rpm.
1307 K Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Significance |
|---|---|---|
| K | Tapered Bore (1:12) | Enables precise mounting on tapered shafts for secure fit and optimal load distribution |
| Open | No Seals/Shields | Allows for custom lubrication schemes and maximum speed capability |
| CN | Normal Radial Clearance | Standard internal clearance suitable for most industrial applications |
1307 K Bearing Structural Features & Performance Benefits
The 1307 K bearing incorporates several key structural features that deliver superior performance:
- Double Row Design: Provides enhanced rigidity and load distribution compared to single row bearings, making it ideal for applications with significant radial loads
- Tapered Bore (1:12): Ensures precise interference fit when mounted on tapered adapter sleeves, eliminating slippage and maintaining positional accuracy
- Nylon Cage: Offers excellent strength-to-weight ratio, reduced friction, and quiet operation at high speeds up to 11,000 rpm
- Chrome Steel Construction: Both rings and balls manufactured from high-grade chrome steel provide exceptional durability and wear resistance
- Optimized Geometry: Carefully calculated shoulder diameters (inner: 51.55 mm, outer: 67.5 mm) ensure proper support and load transfer
1307 K Bearing Typical Application Areas
The 1307 K double row angular contact ball bearing finds extensive use across various industrial sectors:
- Electric Motors - Particularly in medium-sized industrial motors requiring high radial load capacity
- Gearboxes and Transmissions - Where tapered bore mounting provides secure shaft connection
- Industrial Fans and Blowers - Benefiting from the bearing's speed capability and rigidity
- Material Handling Equipment - Conveyor systems and pulley assemblies requiring robust bearing solutions
- Agricultural Machinery - Implement drives and PTO shafts where tapered bore mounting is preferred
- General Industrial Machinery - Various rotating equipment demanding reliable precision bearing performance
