1310K Bearing Product Overview & Core Advantages
The 1310K metric ball bearing is a double row angular contact ball bearing designed for applications requiring high rigidity and the ability to support combined loads. Its double row design provides superior radial load capacity while effectively managing axial loads in both directions. Featuring a tapered bore (1:12) for precise mounting and a lightweight nylon cage, this bearing is engineered for high-speed operation and reliable performance in demanding industrial environments. Its compact dimensions and robust construction make it an ideal choice for high-precision machinery.
1310K Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1310 | Standard bearing series designation indicating the core dimensions: 50mm bore, 110mm OD, 27mm width. |
| K | Denotes a tapered bore with a 1:12 ratio, allowing for precise axial positioning and secure mounting on adapter sleeves or withdrawal sleeves. |
1310K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized internal geometry provide exceptional radial dynamic load rating of 9810 lbf and a radial static load rating of 3150 lbf, enabling stable operation under significant combined loads.
- Precision Tapered Bore: The 1:12 taper bore ensures a tight interference fit on the shaft when used with an adapter sleeve, eliminating slippage and maintaining precise alignment for high-speed applications.
- Optimized High-Speed Performance: The lightweight nylon cage reduces centrifugal forces, lowers friction, and contributes to a high limiting speed of 8,000 rpm. The standard CN radial internal clearance is suitable for most high-speed operations.
- Pre-Lubricated & Ready-to-Use: The bearing is factory-lubricated, ensuring immediate operation and protection during the initial run-in period, simplifying installation and maintenance.
1310K Bearing Typical Application Areas
This double row angular contact ball bearing is ideally suited for:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
- Paper & Printing Machinery
