6210-2RS1/C3WT Bearing Product Overview & Core Advantages
The 6210-2RS1/C3WT is a sealed single row deep groove ball bearing designed for robust performance in demanding applications. This metric bearing excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. Its key advantages include a generous C3 radial internal clearance for thermal expansion management in high-temperature environments, and integrated contact seals (2RS1) that provide superior protection against contaminants. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers reliable, cost-effective precision for a wide range of industrial machinery.
6210-2RS1/C3WT Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning | Benefit |
|---|---|---|
| 6210 | Basic designation: 50mm bore, 90mm OD, 20mm width | Defines the core bearing dimensions. |
| 2RS1 | Double-sided contact seals made of NBR rubber | Provides excellent contamination exclusion and grease retention. |
| C3 | Radial internal clearance greater than Normal group | Prevents preload in applications with thermal expansion or heavy fits. |
| WT | Bearing is supplied without lubrication | Allows for application-specific lubricant selection. |
6210-2RS1/C3WT Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured entirely from chrome steel for rings, balls, and cage, this bearing delivers high strength and durability. With a dynamic load rating of 7891 lbf and a static load rating of 5238 lbf, it is engineered to handle significant radial forces over a long service life.
- Optimized Sealing for Harsh Environments: The 2RS1 contact seals effectively shield the bearing interior from dust, moisture, and other contaminants, making it suitable for dirty or wet operating conditions. This design also ensures the lubricant remains in place, contributing to extended service intervals.
- Thermal Stability & Operational Range: The specified C3 radial clearance is critical for applications where shaft and housing fits are tight or where operational temperatures vary, preventing binding and ensuring smooth rotation. The bearing operates reliably within a temperature range of -30°C to 120°C.
- Balanced High-Speed Performance: The combination of a precision-ground steel cage and optimized internal geometry allows for a limiting speed of 7,100 rpm, making it a versatile choice for various motor and drive applications.
6210-2RS1/C3WT Bearing Typical Application Areas
