6211-2RS1/C3WT Bearing Product Overview & Core Advantages
The 6211-2RS1/C3WT is a single row deep groove ball bearing designed for exceptional reliability 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 sealed design for contamination protection, a generous C3 radial internal clearance for thermal expansion in high-temperature operations, and compliance with ABEC 1 | ISO P0 tolerance standards for consistent performance. Manufactured entirely from chrome steel, it offers high durability and a long service life.
6211-2RS1/C3WT Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Significance & Benefit |
|---|---|---|
| -2RS1 | Contact Seals on Both Sides | Provides superior protection against contaminants like dust and moisture, retaining lubricant effectively for extended maintenance intervals. |
| /C3 | Greater than Normal Radial Internal Clearance | Allows for shaft expansion under high operating temperatures, preventing preload and potential bearing seizure, ideal for applications with significant thermal gradients. |
| WT | Wide Temperature Range | Indicates suitability for a broad operating temperature range from -30°C to 120°C. |
6211-2RS1/C3WT Bearing Structural Features & Performance Benefits
- Robust Sealed Construction: The contact seals (2RS1) are integrated into the bearing's outer ring, creating an effective barrier that significantly extends bearing life by preventing lubricant loss and ingress of harmful particles.
- Optimized Internal Geometry: The deep groove raceway and high-precision chrome steel balls ensure smooth operation, low noise, and vibration, contributing to the bearing's high limiting speed of 6,300 rpm.
- High Load Capacity: With a dynamic load rating of 9757 lbf and a static load rating of 6609 lbf, this bearing is engineered to handle significant radial forces, ensuring reliability under demanding conditions.
- Thermal Stability: The specified C3 clearance is a critical feature for applications where operational heat causes shaft and housing expansion, ensuring consistent performance without binding.
- Material Integrity: All core components—rings, balls, and cage—are made from chrome steel, providing high hardness, wear resistance, and a long operational lifespan.
