1317-K-M-C3 Bearing Product Overview & Core Advantages
The 1317-K-M-C3 is a double row angular contact ball bearing engineered for applications requiring exceptional rigidity and the capacity to handle combined loads. Its metric design features a tapered bore (1:12) for precise interference fits on adapter sleeves or withdrawal sleeves, ensuring secure mounting on shafts. This precision bearing is constructed from high-grade chrome steel and comes pre-lubricated, offering reliable performance and a broad operating temperature range. Its open design and C3 radial internal clearance make it particularly suitable for applications with thermal expansion or heavy loads.
1317-K-M-C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1317 | Standard bore diameter code (85 mm) and series designation. |
| K | Indicates a tapered bore with a 1:12 ratio. |
| M | Designates a brass cage (machined window-type), offering high strength and suitability for demanding applications. |
| C3 | Specifies a greater than normal radial internal clearance, ideal for applications with significant thermal gradients or heavy vibration. |
1317-K-M-C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior rigidity and enables the bearing to sustain substantial radial loads and moderate bidirectional axial loads simultaneously, making it ideal for combined load scenarios.
- Precision Tapered Bore: The K-suffix tapered bore allows for precise axial positioning and a secure, interference fit when mounted with the appropriate sleeve, minimizing slippage and ensuring stable operation.
- Robust Brass Cage: The machined brass cage (M) ensures excellent guidance of the balls, contributing to smooth operation, lower noise levels, and high operational reliability, even at the specified limiting speed of 4,800 rpm.
- Optimized Internal Clearance: The C3 clearance group accommodates thermal expansion of the shaft and housing, preventing preload and potential seizure in high-temperature or high-load applications.
1317-K-M-C3 Bearing Typical Application Areas
This bearing is commonly specified in heavy-duty industrial machinery where high rigidity and reliable performance under combined loads are critical. Key sectors include:
- Vibrating Screens and Conveyors
- Gearboxes and Power Transmission Systems
- Industrial Fans and Blowers
- Agricultural and Construction Machinery
- Paper and Rolling Mill Equipment
