6207-2RS1/C3WT Bearing Product Overview & Core Advantages
The 6207-2RS1/C3WT is a high-performance, sealed deep groove ball bearing designed for demanding industrial applications. This single row bearing excels at handling primarily radial loads and moderate axial loads in both directions. Its key advantages include robust construction for high reliability, a generous C3 radial internal clearance suitable for applications with thermal expansion, and integrated contact seals (2RS1) that provide excellent protection against contaminants. Engineered with precision chrome steel components, it offers a long service life and consistent performance.
6207-2RS1/C3WT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6207 | Basic Bearing Series & Size | Denotes a medium duty, metric deep groove ball bearing with a 35mm bore, 72mm OD, and 17mm width. |
| -2RS1 | Sealing Type | Indicates the bearing is fitted with Rubber Contact Seals on both sides. This provides superior sealing effectiveness compared to non-contact shields, retaining lubricant and excluding moisture and solid contaminants. |
| /C3 | Radial Internal Clearance | Specifies a greater than normal radial internal clearance. This is critical for applications where thermal expansion of the shaft and housing is expected, preventing pre-load and potential bearing failure. |
| WT | Lubrication | Signifies that the bearing is supplied without lubrication ("W" for without, "T" for grease). This allows the end-user to apply a lubricant specific to their operational requirements. |
6207-2RS1/C3WT Bearing Structural Features & Performance Benefits
- Robust Sealed Design: The 2RS1 rubber contact seals are integrally molded and provide an effective barrier against contaminants, making the bearing ideal for dirty or humid environments. This design contributes to lower maintenance needs and extended bearing life.
- Optimized Internal Clearance: The C3 clearance is a key performance feature. It accommodates fits where interference is used on both rings and compensates for differential thermal expansion between the bearing and its surrounding components, ensuring stable operation under varying thermal conditions.
- High-Quality Material & Construction: Manufactured from chrome steel for rings, balls, and cage, this bearing ensures high strength, durability, and resistance to wear. The deep groove raceway geometry is optimized for smooth operation and efficient load distribution.
- Versatile Lubrication Option: Being supplied without grease (WT) offers flexibility. Engineers can select a specialized high-temperature, food-grade, or other performance-specific lubricant to perfectly match the application's speed, load, and environmental conditions.
6207-2RS1/C3WT Bearing Typical Application Areas
The 6207-2RS1/C3WT is a versatile component found in a wide range of industrial machinery. Its combination of sealing, robust construction, and adaptable internal clearance makes it suitable for:
- Electric Motors and Gearboxes
- Industrial Fans and Blowers
- Agricultural Machinery (e.g., conveyors, harvesters)
- Material Handling Equipment (e.g., conveyor rollers, pulleys)
- Pumps and Compressors
- General machinery requiring reliable, sealed bearing solutions in non-precision applications.
