1318-K C/3 Bearing Product Overview & Core Advantages
The 1318-K C/3 is a double row angular contact ball bearing engineered for superior performance in demanding applications. Featuring a tapered bore (1:12) and open design, this precision bearing is optimized to accommodate combined radial and axial loads simultaneously. Its robust construction, utilizing high-grade chrome steel for rings and balls with a stainless steel cage, ensures exceptional rigidity and operational reliability. Pre-lubricated and featuring a standard CN radial internal clearance, it is ready for installation and delivers consistent performance across a wide temperature range.
1318-K C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1318 | Standard bearing series designation, defining the core dimensions (90mm bore, 190mm OD). |
| K | Indicates a tapered bore with a 1:12 ratio, designed for precise mounting on adapter sleeves or withdrawal sleeves. |
| C/3 | Specifies the radial internal clearance group. C3 denotes a clearance greater than normal (CN), suitable for applications with thermal expansion or interference fits. |
1318-K C/3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides a significantly wider effective load zone compared to single row bearings, resulting in superior stiffness and the ability to handle substantial combined (radial and axial) loads from both directions.
- Optimized for Secure Mounting: The tapered bore (1:12) allows for precise axial positioning and a secure, interference fit on a shaft when used with an adapter sleeve, eliminating slippage under heavy loads.
- Durable Construction: Manufactured from chrome steel (AISI 52100 equivalent) for rings and balls, ensuring high fatigue life. The stainless steel cage offers excellent corrosion resistance and durability, contributing to stable operation.
- Ready-to-Use Lubrication: The bearing is pre-lubricated, facilitating immediate startup and reducing maintenance requirements during initial operation.
1318-K C/3 Bearing Typical Application Areas
This bearing is ideally suited for heavy-duty industrial machinery requiring high rigidity and reliable performance under combination loads.
- Gearboxes and Transmissions
- Industrial Pumps and Compressors
- Material Handling Equipment (e.g., conveyor pulleys)
- Vibrating Screens and Mining Machinery
- Agricultural Machinery
