SFR1-4 2rs Bearing Product Overview & Core Advantages
The SFR1-4 2RS is a miniature single row deep groove ball bearing engineered for precision applications requiring compact design and reliable performance. Constructed entirely from stainless steel with integral rubber seals (2RS), this bearing is designed to handle radial loads efficiently. Its inch-series dimensions and ABEC1 precision make it an ideal choice for applications demanding high reliability in confined spaces and challenging environments, offering excellent corrosion resistance and operational stability.
SFR1-4 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| SFR1-4 | Denotes the bearing series and size designation in the inch system. |
| 2RS | Signifies that the bearing is equipped with contact rubber seals on both sides. These seals provide superior protection against contaminants and retain lubricant effectively. |
SFR1-4 2rs Bearing Structural Features & Performance Benefits
- Robust Construction & Corrosion Resistance: The all-stainless steel construction (rings, balls, cage) ensures high corrosion resistance, making it suitable for harsh environments and extending service life.
- Effective Sealing & Contamination Protection: The Nitrile rubber seals (2RS) provide excellent exclusion of contaminants and retention of lubricant, enhancing bearing reliability and reducing maintenance needs.
- Precision & Smooth Operation: Manufactured to ABEC1 tolerance class with an MC3 radial internal clearance, this bearing offers consistent performance and smooth rotation, suitable for a wide range of precision applications.
- High-Speed Capability: With a limiting speed of 60,300 rpm, this bearing is designed for high-speed operation, facilitated by its precision-ground components and optimized internal geometry.
