6309-2RS1NR Bearing Product Overview & Core Advantages
The 6309-2RS1NR is a single row deep groove ball bearing designed for exceptional reliability in demanding applications. This sealed bearing features integrated snap rings for simplified axial location and is pre-lubricated for maintenance-free operation. Its key advantages include the ability to handle significant radial loads and moderate axial loads in both directions, making it a versatile and robust solution for a wide range of industrial machinery. The combination of a snap ring and contact seals ensures easy installation and long-term protection against contamination.
6309-2RS1NR Bearing Model Code Explained, Specifications & Naming Convention
The model number 6309-2RS1NR is decoded as follows:
- 63: Dimension series code indicating a medium width and diameter.
- 09: Bore diameter code; 09 corresponds to a 45 mm bore.
- -2RS1: Signifies two contact seals (RS) made of Nitrile Rubber (NBR), providing excellent protection against contaminants and moisture retention.
- -NR: Indicates the bearing is supplied with a snap ring (fitted) on the outer ring, enabling simplified axial positioning within a housing.
6309-2RS1NR Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel, this bearing delivers a high radial dynamic load rating of 11,915 lbf and a static load rating of 7,194 lbf, ensuring durability under heavy loads.
- Effective Sealing & Contamination Resistance: The 2RS1 contact seals effectively shield the internal components from dust, dirt, and moisture, significantly extending service life in harsh environments.
- Simplified Installation & Axial Location: The integrated snap ring (NR) eliminates the need for complex housing shoulders or end caps, reducing assembly time and cost.
- Standard Precision & Versatility: Conforming to ABEC 1 | ISO P0 tolerance class and CN radial internal clearance, it offers reliable performance for general industrial applications with a limiting speed of 6,700 rpm.
