SF605 2rs Bearing Product Overview & Core Advantages
The SF605 2RS is a sealed single row deep groove ball bearing engineered for precision applications requiring reliable performance in compact spaces. This metric bearing features a 5 mm bore and 14 mm outside diameter, delivering exceptional radial load capacity while maintaining minimal cross-section dimensions. Constructed entirely from stainless steel with nitrile rubber seals, it offers superior corrosion resistance and long service life in demanding environments. The combination of precision ABEC1 tolerance and optimized internal geometry ensures smooth operation and high rotational accuracy, making it ideal for applications where space constraints and reliability are critical factors.
Model Code Detailed Breakdown
| Suffix | Technical Meaning | Performance Benefit |
|---|---|---|
| SF605 | Basic designation indicating 5mm bore, 14mm OD, 5mm width | Standardized bearing dimensions for easy replacement and system integration |
| 2RS | Double-sided contact seals made of nitrile rubber | Enhanced contamination protection and retention of lubrication |
SF605 2rs Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The bearing incorporates 7 precision stainless steel balls with 2.381 mm diameter, strategically arranged to maximize load distribution and minimize stress concentrations. This design ensures smooth operation and extends bearing service life under radial loads.
Superior Sealing Performance: The double-sided nitrile rubber seals (2RS) provide excellent protection against contaminants while effectively retaining lubrication. This sealed construction makes the bearing suitable for applications where maintenance access is limited or environmental conditions are challenging.
Precision Engineering: Manufactured to ABEC1 tolerance standards with controlled radial internal clearance (MC3: 0.002mm to 0.013mm), the bearing delivers consistent performance and reduced vibration across its operating temperature range of -30° to 110°C.
Material Excellence: All bearing components, including rings, balls, and cage, are manufactured from stainless steel, providing excellent corrosion resistance and making the bearing suitable for applications requiring cleanroom compatibility or exposure to mild chemicals.
