1315-K-M-C3 Bearing Product Overview & Core Advantages
The 1315-K-M-C3 is a double row angular contact ball bearing designed for demanding industrial applications requiring exceptional rigidity and the ability to handle combined loads. Featuring a metric tapered bore (1:12) and C3 radial internal clearance, this precision bearing offers superior performance in high-load, moderate-speed environments. Its open design, pre-lubricated for immediate operation, ensures reliable service in a wide temperature range from -30°C to 110°C, making it an ideal choice for robust machinery where high reliability is paramount.
1315-K-M-C3 Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Code | Technical Meaning |
|---|---|---|
| Basic Designation | 1315 | Standard double row angular contact ball bearing series with 75mm bore, 160mm OD |
| Bore Type | K | Tapered bore (1:12) for secure mounting on adapter sleeves |
| Cage Design | M | Machined brass cage providing excellent strength and guidance at moderate speeds |
| Internal Clearance | C3 | Greater than normal clearance for applications with thermal expansion or heavy loads |
1315-K-M-C3 Bearing Structural Features & Performance Benefits
Double Row Design for High Rigidity: The two rows of balls arranged at a contact angle provide significantly higher rigidity compared to single row bearings, making it ideal for applications requiring minimal shaft deflection under heavy combined loads.
Superior Load Capacity: Engineered to accommodate substantial radial loads and bidirectional axial loads simultaneously, with a dynamic load rating of 17,842 lbf and static load rating of 6,750 lbf.
Optimized for Moderate-Speed Operation: The machined brass cage (M) ensures stable operation and excellent guidance, contributing to reliable performance at limiting speeds up to 5,600 rpm.
Tapered Bore Mounting Advantage: The 1:12 tapered bore (K) enables precise axial positioning and secure fitting using adapter sleeves, eliminating fretting corrosion and ensuring vibration-free operation.
Pre-Lubricated & Ready for Service: Factory-lubricated for immediate installation and operation, reducing maintenance requirements and ensuring consistent performance throughout the specified temperature range.
