61809-2RS1 Bearing Product Overview & Core Advantages
The 61809-2RS1 is a metric single row deep groove ball bearing designed for high-precision applications requiring reliable performance in compact spaces. This sealed bearing excels in handling primarily radial loads while offering excellent operational characteristics. Its key advantages include a P6 tolerance class for superior dimensional accuracy, pre-lubricated with grease for immediate use, and sealed construction providing effective contamination protection. The combination of chrome steel rings and stainless steel cage ensures durability and consistent performance across a wide temperature range from -30°C to 120°C.
61809-2RS1 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 61809 | Basic bearing designation: 45mm bore, 58mm OD, 7mm width | Compact dimensions for space-constrained applications |
| 2RS1 | Double rubber contact seals on both sides | Superior contamination exclusion and grease retention |
61809-2RS1 Bearing Structural Features & Performance Benefits
Optimized Single Row Design: The deep groove raceway geometry enables efficient radial load distribution while accommodating moderate axial loads in both directions. This makes it suitable for applications requiring combination loading capability.
Enhanced Sealing System: The 2RS1 rubber contact seals provide excellent protection against contaminants while retaining lubrication effectively. This contributes to extended service life and maintenance-free operation in demanding environments.
Precision Manufacturing: Manufactured to P6 tolerance class with CN radial internal clearance, ensuring consistent performance and smooth operation. The stainless steel cage provides reliable guidance and stability at the specified limiting speed of 6,700 rpm.
Material Excellence: Constructed with chrome steel rings and chrome steel balls for high load capacity and durability. The combination delivers a radial dynamic load rating of 1,490 lbf and radial static load rating of 1,371 lbf.
