Product Overview and Core Advantages
The SFR2-5 2RS is a sealed miniature ball bearing designed for precision applications requiring reliable performance in compact spaces. This single row deep groove ball bearing features integrated rubber seals (2RS) that provide excellent contamination protection while maintaining smooth operation. Manufactured entirely from stainless steel (rings, balls, and cage), it offers superior corrosion resistance and is ideal for applications where lubrication maintenance is challenging. With its ABEC1 precision class and optimized internal geometry, this bearing delivers consistent performance across a wide temperature range from -86 to 230 °F.
SFR2-5 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| SFR2-5 | Standard flange bearing series with 1/8" bore diameter | Compact design with integrated mounting flange for easy installation |
| 2RS | Double rubber contact seals on both sides | Superior protection against contaminants and moisture ingress |
Structural Features and Performance Benefits
Enhanced Sealing Performance: The dual nitrile rubber contact seals (2RS) provide effective barrier against dust, debris, and moisture while retaining lubrication, making this bearing suitable for harsh operating environments.
Corrosion Resistance: Constructed entirely from stainless steel components, this bearing offers excellent resistance to corrosion and chemical exposure, ensuring long service life in demanding conditions.
Precision Engineering: With ABEC1 tolerance class and MC3 radial internal clearance (0.00008" to 0.0005"), this bearing delivers consistent rotational accuracy and smooth operation essential for precision applications.
Optimized Load Capacity: The deep groove raceway design enables efficient handling of radial loads (96 lbf dynamic, 29 lbf static) while accommodating moderate axial loads in both directions.
Integrated Flange Design: The flange outer diameter of 0.359" with 0.031" thickness provides secure mounting and precise positioning, simplifying assembly and reducing installation costs.
