6305-2RSNR Bearing Product Overview & Core Advantages
The 6305-2RSNR is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. This sealed bearing features an integral snap ring on its outer ring, enabling simplified axial location within a housing. Engineered with precision tolerances (ABEC 1 | ISO P0) and manufactured from high-grade chrome steel, it delivers consistent performance, high limiting speed capabilities, and robust radial load capacity. Its compact design and pre-lubricated, sealed construction make it an ideal, low-maintenance solution for a wide range of industrial machinery.
6305-2RSNR Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6305 | Basic bearing designation indicating a medium duty series with a 25mm bore diameter. |
| 2RS | Signifies contact seals on both sides of the bearing. This provides superior protection against contaminants and retains lubricant effectively. |
| NR | Indicates a snap ring groove and a fitted snap ring on the outer ring. This feature simplifies axial positioning and reduces housing design complexity. |
6305-2RSNR Bearing Structural Features & Performance Benefits
- Robust Sealing & Contamination Resistance: The 2RS (double-contact seals) provide an effective barrier against dust, moisture, and other contaminants, significantly extending bearing service life in harsh environments and making it a maintenance-free component.
- Simplified Assembly & Axial Location: The integrated snap ring (NR) eliminates the need for complex housing shoulders or separate retaining components. This feature ensures secure axial location, reduces assembly time, and lowers overall system cost.
- High-Speed Capability & Precision: Manufactured to ABEC 1 / ISO P0 tolerance class with optimized internal geometry, this bearing offers smooth operation and is capable of high limiting speeds (up to 11,000 rpm). The standard CN radial internal clearance ensures reliable performance under normal operating conditions.
- High Load Capacity & Durability: Constructed entirely from chrome steel, including the balls and cage, the bearing provides a high dynamic load rating of 4631 lbf, ensuring long-term durability and reliability under significant radial loads.
