SF627 2rs Bearing Product Overview & Core Advantages
The SF627 2RS is a metric single row deep groove ball bearing designed for exceptional reliability in demanding applications. Featuring stainless steel construction throughout its rings, balls, and cage, it offers superior corrosion resistance. Its key advantage lies in the integrated rubber seals (2RS) on both sides, which effectively retain lubrication and exclude contaminants, making it a robust, maintenance-free solution for applications requiring long service life and consistent performance under radial loads.
SF627 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SF627 | Basic bearing designation indicating specific bearing dimensions (7mm bore, 22mm OD, 7mm width). |
| 2RS | Denotes contact rubber seals on both sides of the bearing for superior protection against contamination and grease leakage. |
SF627 2rs Bearing Structural Features & Performance Benefits
- Robust Sealing: The Nitrile Rubber (NBR) seals (2RS) provide excellent exclusion of contaminants like dust and moisture, while effectively retaining the lubricant. This design significantly enhances bearing life in harsh environments and supports a maintenance-free operational philosophy.
- Full Stainless Steel Construction: Manufactured from stainless steel for the rings, balls, and cage, this bearing offers high corrosion resistance, making it ideal for applications exposed to water, chemicals, or washdowns.
- Optimized Internal Geometry: The deep groove raceway and the complement of seven precision balls enable efficient handling of radial dynamic loads up to 566 lbf and facilitate smooth, quiet operation.
- Standard ABEC1 Precision: Manufactured to ABEC1 tolerance class, ensuring reliable performance for a wide range of industrial applications with consistent running accuracy.
