SFRW2 Bearing Product Overview & Core Advantages
The R1-2RS is a single row deep groove ball bearing designed for high-performance applications requiring compact design and reliable operation. Engineered with a flanged outer ring for simplified mounting and precise axial location, this bearing excels in handling radial loads efficiently. Manufactured entirely from stainless steel, it offers excellent corrosion resistance and is suitable for a wide operating temperature range. Its construction ensures smooth operation and is ideal for applications demanding ABEC1 precision and consistent performance in challenging environments.
SFRW2 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| R1 | Standard series designation for a specific inch-size, flanged deep groove ball bearing. |
| 2RS | Indicates the bearing is fitted with contact seals on both sides, providing effective protection against contaminants and retaining lubricant. |
SFRW2 Bearing Structural Features & Performance Benefits
- Flanged Design: The integral flange on the outer ring facilitates easy installation and accurate positioning within the housing, reducing assembly time and cost.
- Deep Groove Raceway: Optimized for handling radial loads, ensuring stable and quiet operation.
- Stainless Steel Construction: All components, including rings, balls, and cage, are made from stainless steel, providing superior corrosion resistance and making the bearing suitable for washdown environments or applications exposed to moisture.
- Sealed for Protection: The 2RS double-contact seals effectively shield the internal components from dust, dirt, and moisture, while also retaining lubrication for extended service life.
- Precision Performance: Manufactured to ABEC1 tolerance class, ensuring reliable and consistent running accuracy for a wide range of industrial applications.
