1315C3 Bearing Product Overview & Core Advantages
The 1315C3 is a double row angular contact ball bearing designed for exceptional performance in demanding applications. This precision bearing excels at simultaneously handling significant combined loads, including radial and bidirectional axial forces. Its robust double row construction provides superior high rigidity and stability, making it ideal for machinery requiring high reliability and operational accuracy. With a generous C3 radial internal clearance, it is well-suited for applications involving thermal expansion or where interference fits are used.
1315C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 1315 | Standard Bearing Series & Size Designation | Indicates the core bearing dimensions: 75mm bore, 160mm OD, 37mm width. |
| C3 | Radial Internal Clearance Group | Specifies a greater than normal radial internal clearance, accommodating thermal expansion and interference fits. |
| (Open) | Seal Type | No seals or shields, allowing for high-speed operation and custom lubrication regimes. |
1315C3 Bearing Structural Features & Performance Benefits
- High Rigidity & Stability: The double row ball design and robust construction provide exceptional resistance to deflection and moment loads, ensuring precise shaft positioning and high rigidity.
- Superior Load Capacity: Engineered to handle significant combined loads. The optimized contact angle allows it to support heavy radial loads alongside substantial axial loads from both directions.
- High-Speed Capability: The standard stainless steel cage ensures low friction and high strength, contributing to a limiting speed of 5,600 rpm. The open design facilitates efficient lubrication and heat dissipation.
- Precision & Durability: Manufactured from chrome steel for both rings and balls, this bearing offers high fatigue life and wear resistance. The tight dimensional tolerances guarantee consistent precision bearing performance.
- Operational Flexibility: The C3 clearance provides operational tolerance for thermal expansion and press fits, reducing the risk of seizure under demanding conditions.
1315C3 Bearing Typical Application Areas
The 1315C3 bearing is ideally suited for a wide range of industrial machinery where high rigidity and combined load capacity are critical. Key application areas include:
- Industrial Gearboxes and Power Transmission Systems
- Heavy-Duty Pumps and Compressors
- Material Handling Equipment (Conveyors, Pulleys)
- Construction and Agricultural Machinery
- Mining Equipment and other robust industrial applications
