6315-Z/C2 Bearing Product Overview & Core Advantages
The 6315-Z/C2 is a single row deep groove ball bearing engineered for superior performance in demanding industrial applications. This metric bearing features a shielded design on one side, offering effective protection against contaminant ingress while maintaining high-speed capability. Its key advantages include a high radial dynamic load rating of 25,403 lbf and a C2 radial internal clearance, which is tighter than standard, making it ideal for applications requiring precise shaft positioning and reduced noise and vibration levels. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures reliable and consistent operation.
6315-Z/C2 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Benefit |
|---|---|---|
| -Z | One side shielded | Protects the bearing interior from large particulate contaminants, enhancing service life. The unshielded side allows for easy re-lubrication if required. |
| /C2 | C2 radial internal clearance group | Provides a clearance smaller than the Normal (CN) group. This is advantageous for applications with tight fit-ups, minimizing preload and reducing operational noise and heat generation. |
6315-Z/C2 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Built entirely from chrome steel for rings, balls, and cage, this bearing delivers high strength and durability. The single row deep groove raceway geometry is optimized to support high radial loads and moderate axial loads in both directions.
- Optimized for Precision: The C2 radial internal clearance ensures minimal play in the bearing assembly, leading to higher running accuracy, precise shaft guidance, and smoother operation, which is critical for machinery with stringent positional tolerances.
- Effective Contamination Control: The steel shield (-Z) on one side acts as a physical barrier, protecting the rolling elements and raceways from dust and debris, thereby extending the bearing's operational lifespan in challenging environments.
- Wide Operating Range: With a specified operating temperature range from -30°C to 120°C, this bearing is suitable for a variety of industrial climates and conditions.
6315-Z/C2 Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Electric Motors and Generators
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Pumps and Fans
