6212-2RS1/C3WT Bearing Product Overview & Core Advantages
The 6212-2RS1/C3WT is a metric single row deep groove ball bearing engineered for reliable performance in demanding applications. Its primary advantage lies in its ability to efficiently handle radial loads while offering robust construction for consistent operation. The bearing features integral sealed design with synthetic rubber seals (2RS1) on both sides, providing excellent protection against contaminants and retaining lubrication. Pre-lubricated for life, it offers a maintenance-free solution. The C3 radial internal clearance makes it suitable for applications with anticipated thermal expansion or where interference fits are used, ensuring optimal performance across its specified temperature range from -30° to 120°C.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 6212 | Basic series number, indicating a single row deep groove ball bearing with a 60mm bore, 110mm OD, and 22mm width. |
| 2RS1 | Contact synthetic rubber seals on both sides. Provides superior sealing effectiveness compared to non-contact shields. |
| C3 | Radial internal clearance greater than Normal (C0). Suitable for applications with expected thermal gradients or tight fits. |
| WT | Indicates the bearing is supplied with an extreme temperature grease fill, compatible with the specified operating temperature range. |
6212-2RS1/C3WT Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel for rings, balls, and cage, this bearing delivers high strength and durability. It is rated for a dynamic load capacity of 1178 lbf and a static load capacity of 8138 lbf, making it capable of handling significant radial loads.
- Effective Sealing & Maintenance-Free Operation: The double-sealed (2RS1) design effectively excludes contaminants like dust and moisture while retaining the factory-applied grease. This creates a maintenance-free solution, reducing lifecycle costs and downtime.
- Optimized for Operational Stability: The C3 clearance accommodates dimensional changes from thermal expansion or press-fits, preventing premature failure due to excessive preload. Combined with the ABEC 1 (ISO P0) tolerance class, it ensures smooth and reliable running.
- Wide Temperature Suitability: The standard extreme temperature grease (WT) allows for continuous operation within a -30° to 120 °C range, enhancing its versatility across different environments.
