6309-2RSNR Bearing Product Overview & Core Advantages
The 6309-2RSNR is a single row deep groove ball bearing designed for exceptional performance in demanding industrial applications. This sealed bearing features a snap ring groove on its outer ring, enabling simplified axial location within a housing. Its primary advantages include high radial load capacity and reliable operation due to its integrated seals, which protect against contamination. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers consistent quality and is pre-lubricated for immediate use, making it an ideal ready-to-install component for various machinery.
6309-2RSNR Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Advantage |
|---|---|---|
| 6309 | Standard bearing series designation indicating a medium duty, single row deep groove ball bearing with a 45mm bore. | Widely available and standardized dimensions. |
| 2RS | Designates contact seals on both sides of the bearing. | Provides excellent contamination protection, retaining lubricant and excluding moisture and debris. |
| NR | Indicates a snap ring groove on the outer ring. | Simplifies axial location and reduces assembly costs by eliminating the need for a complex housing design. |
6309-2RSNR Bearing Structural Features & Performance Benefits
Robust Construction for High Loads: Manufactured from chrome steel for both rings, balls, and cage, this bearing delivers high strength and durability. With a dynamic load rating of 11,915 lbf and a static load rating of 7,194 lbf, it is engineered to handle significant radial loads in continuous operation.
Integrated Sealing Solution: The 2RS double-contact seals effectively shield the internal components from contaminants, making the bearing suitable for harsh environments. This sealing also ensures the pre-applied lubricant is retained, contributing to a long service life with minimal maintenance.
Simplified Mounting with Snap Ring: The outer ring snap ring groove (NR) is a key feature that allows for secure axial positioning. This design simplifies the housing structure, leading to faster assembly and potential cost savings in the overall machine design.
Standardized Precision: Conforming to ABEC 1 (ISO P0) tolerance class and CN radial internal clearance, this bearing provides reliable, consistent performance for a wide range of general industrial applications.
