1318 Bearing Product Overview & Core Advantages
The 1318 is a metric double row angular contact ball bearing engineered for applications demanding high rigidity and reliable performance under combined loads. Its open design, precision-ground chrome steel rings and balls, and stainless steel cage construction enable it to handle significant radial loads while accommodating axial loads in both directions. This makes the 1318 bearing an ideal, compact solution for high-precision machinery requiring robust support and long-term operational stability.
1318 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Significance |
|---|---|
| 1318 | Standard bearing designation indicating the bearing size (90mm bore, 190mm OD). |
| Open | No integral seals or shields, allowing for higher speeds and custom lubrication schemes. Requires a well-sealed housing environment. |
| Lubricated | The bearing is supplied with a general-purpose grease, ready for initial operation. |
1318 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and optimized internal geometry provide superior rigidity, enabling the bearing to withstand substantial radial dynamic load ratings of 26,325 lbf and effectively manage combined loads.
- Precision & Durability: Manufactured from high-grade chrome steel for rings and balls, ensuring high wear resistance and dimensional stability under load. The stainless steel cage offers excellent corrosion resistance and durability, contributing to reliable performance.
- High-Speed Capability: The open design and robust stainless steel cage allow for a limiting speed of 4,500 rpm, making it suitable for various high-speed applications.
- Protrusion Design: The 1mm ball protrusion from the side faces is a key feature of many angular contact bearings, facilitating optimal contact angles for handling thrust loads.
1318 Bearing Typical Application Areas
- Industrial Gearboxes and Transmissions
- Medium-duty Pump and Compressor Systems
- Material Handling Conveyor Systems
- Agricultural Machinery
- General Industrial Machinery requiring robust, double row support
