6215-2Z/C3WT Bearing Product Overview & Core Advantages
The 6215-2Z/C3WT is a single row deep groove ball bearing engineered for high performance and reliability in demanding industrial applications. This shielded bearing is designed to primarily accommodate radial loads while also handling moderate axial loads in both directions. Its key advantages include a generous C3 radial internal clearance for applications involving thermal expansion or heavy loads, and robust chrome steel construction for enhanced durability. The integral shields (2Z) provide effective contaminant protection, making it a robust, long-lasting component suitable for a wide operational temperature range.
6215-2Z/C3WT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6215 | Basic bearing designation denoting a single row deep groove ball bearing with a 75 mm bore and 130 mm outside diameter. |
| 2Z | Signifies bearing is shielded on both sides. This provides excellent protection against solid contaminants while allowing for higher limiting speeds compared to contact seals. |
| C3 | Indicates a greater than normal radial internal clearance. This is critical for applications with expected thermal expansion, heavy loads, or where fit-up creates a reduction in clearance. |
| WT | This suffix denotes that the bearing is supplied without lubrication (Dry). This allows the end-user to apply a specific lubricant tailored to their application's unique requirements. |
6215-2Z/C3WT Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The deep groove raceway and high-quality chrome steel construction provide a high radial dynamic load rating of 15,152 lbf and a static load rating of 10,858 lbf, ensuring reliable performance under significant stress.
- Enhanced Operational Stability: The C3 clearance is a key structural feature that accommodates thermal expansion and interference fits, preventing premature failure due to excessive preload and ensuring smooth operation.
- High-Speed Capability: The combination of non-contact shields (2Z) and a precision ABEC 1 | ISO P0 tolerance class allows for a high limiting speed of 4,800 rpm, minimizing friction and heat generation.
- Versatile & Customizable Lubrication: Being supplied without grease (WT) offers maximum flexibility. Engineers can select a specialized lubricant to optimize performance for extreme temperatures, high speeds, or specific environmental conditions.
6215-2Z/C3WT Bearing Typical Application Areas
This bearing is ideally suited for a wide range of industrial machinery and equipment, including:
- Electric Motors and Generators
- Industrial Gearboxes and Power Transmission Systems
- Material Handling Equipment such as conveyor pulleys
- Agricultural Machinery
- Ventilation and Fan Systems
