1318-K-M-C3 Bearing Product Overview & Core Advantages
The 1318-K-M-C3 is a double row angular contact ball bearing engineered for demanding applications requiring high rigidity and precise operation. Featuring a tapered bore (1:12) for secure shaft mounting, this precision bearing is designed to accommodate significant combined loads, including radial forces and bidirectional axial loads. Its robust construction ensures exceptional stability, making it ideal for high-performance machinery where accuracy and reliability are paramount. The bearing is pre-lubricated and features a generous C3 radial internal clearance, suitable for applications with thermal expansion or heavy load conditions.
Model Code Breakdown
| Suffix Code | Technical Meaning | Significance & Advantage |
|---|---|---|
| K | Tapered Bore (1:12) | Enables precise axial positioning and secure interference fit on the shaft, reducing slippage under heavy loads. |
| M | Brass Cage | Provides high strength and excellent guidance for the balls, contributing to stable operation at moderate speeds. |
| C3 | Radial Internal Clearance (Greater than Normal) | Accommodates thermal expansion and heavy load deformations, preventing premature failure due to preload. |
1318-K-M-C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design and optimized contact angles provide superior stiffness, enabling the bearing to handle substantial combined radial and axial loads from both directions simultaneously. This makes it exceptionally stable under complex loading conditions.
- Optimized for Demanding Environments: The open design allows for efficient re-lubrication in service. The standard pre-lubrication ensures immediate operational readiness. The generous C3 clearance is specifically selected for applications prone to shaft expansion or heavy shock loads, ensuring consistent performance and longevity.
- Durable Construction: Components made from chrome steel and a brass cage offer excellent wear resistance and durability. The specified bearing dimensions and tight tolerances guarantee precise fit and reliable operation in the assembly.
1318-K-M-C3 Bearing Typical Application Areas
This bearing is ideally suited for heavy-duty industrial equipment where high rigidity and the ability to handle combined loads are critical. Key applications include:
- Industrial Gearboxes and power transmission systems
- Vibrating Screens and other material handling equipment
- Pump and Compressor Shafts
- Agricultural Machinery and construction equipment
- Heavy-duty Electric Motors
