1315-M-C2 Bearing Product Overview & Core Advantages
The 1315-M-C2 is a double row angular contact ball bearing engineered for demanding applications requiring high rigidity and precision. This metric bearing is designed to accommodate significant combined loads, including substantial radial forces and bidirectional axial loads, within a compact envelope. Its open design, coupled with a C2 radial internal clearance, makes it an excellent choice for high-speed operations and scenarios where thermal expansion must be managed. Manufactured from high-grade chrome steel and featuring a robust brass cage, it delivers reliable performance and long service life in precision machinery.
1315-M-C2 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1315 | Standard bearing series designation, indicating the core bearing dimensions (75mm bore, 160mm OD, 37mm width). |
| M | Indicates the bearing is supplied with a brass cage (machined window-type). This cage offers superior strength and guidance, contributing to high-speed capability and stability. |
| C2 | Specifies the radial internal clearance group. C2 clearance is smaller than the normal CN group, making it suitable for applications requiring precise shaft positioning, high speeds, or where minimal internal play is critical for performance. |
1315-M-C2 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design effectively doubles the contact angle, providing superior high rigidity and enabling the bearing to support heavy combined loads (radial and axial) simultaneously. This makes it ideal for applications with complex loading conditions.
- Optimized for High-Speed Operation: The precision-machined brass cage (M) ensures excellent ball guidance and stability, reducing friction and wear at high rotational speeds. The C2 internal clearance further supports high-speed performance by managing thermal expansion.
- Precision & Durability: Components made from chrome steel provide high hardness and fatigue resistance. The open seal type allows for optimal lubrication flow, which is essential for heat dissipation in high-speed and high-load scenarios.
- Pre-Lubricated for Immediate Use: The bearing is supplied lubricated, ensuring it is ready for installation and initial operation, reducing setup time and potential for initial dry-running damage.
1315-M-C2 Bearing Typical Application Areas
The 1315-M-C2 is a versatile precision bearing found in a wide range of industrial machinery where reliability under combined loads and high speeds is paramount. Key applications include:
- Machine Tool Spindles
- Gearboxes and Transmissions
- Industrial Pumps and Compressors
- Precision Agricultural Equipment
- Material Handling Systems
