6011-2RS1/C3WT Bearing Product Overview & Core Advantages
The 6011-2RS1/C3WT is a metric single row deep groove ball bearing engineered for reliable performance in demanding industrial applications. Its core advantages stem from its sealed design and optimized internal geometry, enabling it to handle significant radial loads and moderate axial loads in both directions. The bearing is manufactured to ABEC 1 | ISO P0 tolerance standards, ensuring consistent quality and interchangeability. Its C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used, providing operational stability and high reliability.
6011-2RS1/C3WT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Advantage |
|---|---|---|
| 6011 | Basic designation indicating a metric deep groove ball bearing with a 55mm bore, 90mm OD, and 18mm width. | Standardized dimensions for easy replacement and sourcing. |
| 2RS1 | Contact Rubber Seals on both sides. | Provides effective protection against contaminants and retains lubricant, enhancing bearing service life in harsh environments. |
| C3 | Radial internal clearance greater than Normal (C0) group. | Accommodates thermal expansion from high speeds or interference fits, preventing premature failure due to excessive preload. |
| WT | Not explicitly defined in provided data, but commonly indicates a specific manufacturer's designation or variant. Based on spec "Lubrication: None". | Supplied without factory grease, allowing for application-specific lubrication. |
6011-2RS1/C3WT Bearing Structural Features & Performance Benefits
- Robust Sealed Construction: The double-sided 2RS1 rubber seals effectively shield the bearing's internal components from dust, moisture, and other particulate contaminants. This design significantly increases operational reliability and is ideal for applications where re-lubrication is difficult or impossible.
- High Load Capacity: Manufactured from chrome steel for both rings and balls, this bearing offers a high dynamic load rating of 6362 lbf and a static load rating of 4766 lbf. The deep groove raceway geometry is optimized to support substantial radial loads and moderate axial loads from either direction.
- Versatile Internal Clearance: The C3 clearance provides greater operational flexibility. It is the preferred choice for applications involving expected thermal expansion, heavy vibration, or where shaft and housing fits result in a reduction of the original internal clearance.
- Precision and Consistency: Built to ABEC 1 | ISO P0 tolerance class, this bearing ensures smooth and quiet operation, contributing to the overall efficiency and longevity of the machinery it serves.
6011-2RS1/C3WT Bearing Typical Application Areas
