6011-2RS1/C3 Bearing Product Overview & Core Advantages
The 6011-2RS1/C3 is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This sealed bearing excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. Its key advantage lies in its combination of a generous C3 radial internal clearance and integrated contact seals (2RS1), making it an ideal choice for applications with thermal expansion challenges or where robust contamination protection is required. The ABEC 1 (ISO P0) tolerance class ensures reliable and consistent operation.
6011-2RS1/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Benefit |
|---|---|---|
| 6011 | Basic designation indicating a metric single row deep groove ball bearing with a 55mm bore, 90mm OD, and 18mm width. | Defines the standard bearing dimensions and type. |
| 2RS1 | Bearing is fitted with two contact seals (one on each side) made from Nitrile Rubber (NBR). | Provides superior protection against contaminants and retains lubricant, enhancing service life. |
| C3 | Specifies a greater than normal radial internal clearance. | Accommodates thermal expansion in shafts or housings, preventing preload and potential seizure in high-temperature applications. |
6011-2RS1/C3 Bearing Structural Features & Performance Benefits
- Robust Sealing: The 2RS1 contact seals effectively shield the bearing's internals from dust, moisture, and other particulate contaminants, making it suitable for harsh environments and contributing to its long service life.
- Optimized Internal Clearance: The C3 clearance is a critical feature for applications involving elevated operating temperatures or where fits result in a reduction of internal clearance. This prevents binding and ensures smooth, low-friction rotation.
- High Load Capacity: Manufactured from high-grade 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, providing reliable performance under significant radial loads.
- Ready-to-Install: The bearing comes pre-greased and sealed, making it a maintenance-free component that is ready for immediate installation, reducing assembly time and complexity.
6011-2RS1/C3 Bearing Typical Application Areas
This versatile bearing is commonly specified in a wide range of industrial machinery, including:
- Electric Motors and Generators
- Industrial Gearboxes and Power Transmission Systems
- Agricultural Machinery (e.g., conveyors, augers)
- Material Handling Equipment (e.g., pulleys, rollers)
- Pumps and Blowers
- General Industrial Machinery requiring reliable, sealed ball bearing solutions.
