6311-RS1/C3 Bearing Product Overview & Core Advantages
The 6311-RS1/C3 is a single row deep groove ball bearing engineered for superior performance in demanding industrial applications. This sealed bearing is designed to handle significant radial loads and moderate axial loads in both directions. Its key advantages include robust construction, reliable operation, and extended service life due to its integrated sealing and optimized internal geometry. The C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used, ensuring consistent performance under varying operating conditions.
6311-RS1/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6311 | Standard bearing series designation | Defines the basic dimensions: 55mm bore, 120mm OD, 29mm width |
| RS1 | Contact rubber seal on one side | Provides effective protection against contaminants while retaining lubricant |
| C3 | Greater than normal radial internal clearance | Accommodates thermal expansion and interference fits, preventing premature failure |
6311-RS1/C3 Bearing Structural Features & Performance Benefits
Robust Construction & High Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing delivers exceptional durability. With a dynamic load rating of 16,096 lbf and a static load rating of 10,116 lbf, it is built to withstand substantial radial forces in continuous operation.
Effective Sealing & Contamination Protection: The RS1 contact seal provides a superior barrier against dust, moisture, and other contaminants, significantly extending the bearing's operational life in harsh environments.
Optimized Internal Clearance for Versatility: The C3 clearance is a critical feature for applications involving elevated temperatures or press-fits onto shafts/housings. It prevents excessive preload and potential seizure, ensuring reliable performance.
High-Speed Capability & Precision: Manufactured to ABEC 1 | ISO P0 tolerance class, it offers excellent running accuracy. The limiting speed of 5,600 rpm makes it suitable for a wide range of high-speed machinery.
