6311-2RS1NR Bearing Product Overview & Core Advantages
The 6311-2RS1NR is a sealed single row deep groove ball bearing engineered for exceptional reliability in demanding applications. This metric bearing is characterized by its ability to handle significant radial loads while offering protection against contamination. A key feature is the integrated snap ring on the outer ring, which simplifies axial location within a housing, reducing assembly time and cost. Manufactured to ABEC 1 | ISO P0 tolerance standards, it provides consistent performance and is compliant with RoHS and REACH directives, making it a robust and versatile choice for industrial machinery.
6311-2RS1NR Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning | Advantage |
|---|---|---|
| -2RS1 | Contact seals on both sides | Provides excellent protection against the ingress of contaminants like dust and moisture, extending bearing service life. |
| -NR | Snap ring groove and snap ring fitted on the outer ring | Enables secure and simplified axial location, eliminating the need for complex housing shoulders and reducing assembly costs. |
6311-2RS1NR Bearing Structural Features & Performance Benefits
- Robust Load Capacity: With a dynamic load rating of 16,096 lbf and a static load rating of 10,116 lbf, this bearing is designed to handle substantial radial forces in continuous operation.
- Sealed for Protection: The double-sided contact seals (-2RS1) effectively retain grease and exclude harmful particles, making the bearing suitable for dirty or humid environments and contributing to a maintenance-free design.
- Simplified Mounting: The presence of the snap ring (-NR) provides a positive axial locating feature, ensuring the bearing remains correctly positioned without additional components, enhancing design efficiency.
- Standard Precision & Clearance: Manufactured to ABEC 1 (ISO P0) tolerance with CN group radial internal clearance, it offers reliable performance for a wide range of general industrial applications.
6311-2RS1NR Bearing Typical Application Areas
This bearing's combination of high radial load capacity, integrated sealing, and ease of installation makes it ideal for various sectors, including:
- Electric Motors and Generators
- Industrial Gearboxes
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- General Industrial Machinery requiring reliable, sealed bearing solutions.
