1315 K/C3 Bearing Product Overview & Core Advantages
The 1315 K/C3 is a metric double row angular contact ball bearing engineered for demanding applications requiring high load capacity and operational stability. Featuring a tapered bore (1:12 ratio) and C3 radial internal clearance, this bearing is optimized to handle significant combined loads—simultaneously supporting substantial radial forces while accommodating axial loads in both directions. Its double-row ball construction provides enhanced rigidity and rotational accuracy, making it an ideal choice for heavy-duty machinery and precision equipment where reliable performance under strenuous conditions is paramount.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1315 | Standard bearing series designation, indicating specific dimensional series (bore: 75mm, OD: 160mm, width: 37mm). |
| K | Indicates a tapered bore with a 1:12 ratio, facilitating precise mounting and interference fit on tapered shafts. |
| C3 | Specifies a greater radial internal clearance than normal, suitable for applications with thermal expansion or where interference fits are used. |
1315 K/C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact design provides superior stiffness and enables the bearing to sustain high radial dynamic load ratings (17,842 lbf) and static loads (6,750 lbf), effectively managing combined loading scenarios.
- Precision Tapered Bore: The 1:12 tapered bore ensures a secure, interference fit on matching shafts, minimizing slippage and maintaining alignment under heavy loads and high speeds.
- Optimized High-Speed Performance: Equipped with a lightweight nylon cage that reduces centrifugal forces, contributing to smooth operation at elevated speeds (limiting speed: 5,600 rpm).
- Wide Operating Range: Manufactured from chrome steel for both rings and balls, the bearing operates reliably across a temperature range of -30°C to 110°C and comes pre-lubricated for immediate use.
- Industrial Compliance: Fully compliant with ROHS and REACH standards, ensuring environmental safety and material sustainability.
