6309-2RS1 Bearing Product Overview & Core Advantages
The 6309-2RS1 is a single row deep groove ball bearing designed for exceptional performance in demanding applications. Engineered with metric dimensions and manufactured to P6 tolerance class, this bearing delivers high precision and reliable operation. Its key advantage lies in its ability to accommodate significant radial loads, making it an ideal choice for a wide range of industrial machinery. The integrated contact seals (2RS1) effectively retain lubrication and exclude contaminants, ensuring long service life and reduced maintenance requirements. This combination of high load capacity, precision, and sealed construction makes it a robust and dependable component for high-reliability applications.
6309-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6309 | Basic bearing series; denotes a medium-duty, single row deep groove ball bearing with a 45 mm bore, 100 mm OD, and 25 mm width. |
| 2RS1 | Designates contact seals on both sides of the bearing. The RS1 seal type is made of Nitrile Rubber (NBR), providing excellent protection against contaminants and effective grease retention. |
6309-2RS1 Bearing Structural Features & Performance Benefits
- High Load Capacity and Rigidity: The single row deep groove raceway geometry and high-quality chrome steel construction enable high radial dynamic load rating of 12,432 lbf and a radial static load rating of 7,081 lbf, providing robust support for rotating shafts.
- Sealed and Pre-Lubricated for Longevity: The 2RS1 seals create an effective barrier against dust, moisture, and other particulate matter. The bearing is pre-lubricated with grease, making it ready for installation and offering a maintenance-free solution within its specified temperature range of -30°C to 120°C.
- Precision Performance: Manufactured to P6 tolerance class with a CN radial internal clearance, this bearing ensures smooth, quiet, and precise operation, contributing to the overall accuracy of the application.
- Durable Cage Design: The stainless steel cage provides superior strength and corrosion resistance, contributing to stable performance at the limiting speed of 4,500 rpm.
