SFR6 2rs Bearing Product Overview & Core Advantages
The SFR6 2RS is a sealed single row deep groove ball bearing designed for reliable performance in demanding applications. Engineered with stainless steel construction throughout its rings, balls, and cage, it offers excellent corrosion resistance. Its primary advantages include the ability to handle radial loads efficiently, with a dynamic load rating of 574 lbf, and its sealed design which protects against contaminants while retaining lubrication. This bearing is characterized by its compact inch dimensions (0.375" bore, 0.875" OD) and is built to ABEC1 precision tolerances, making it a robust and dependable choice for applications requiring consistent operation and longevity.
SFR6 2rs Bearing Model Code Explained, Specifications & Naming Convention
| Suffix / Prefix | Technical Meaning | Benefit |
|---|---|---|
| SFR | Flanged Bearing Series | Simplifies mounting and positioning with a flange outer diameter of 0.965". |
| 6 | Size Code | Defines the specific bearing dimensions (0.375" bore, 0.875" OD, 0.2812" width). |
| 2RS | Double Rubber Seals (Both Sides) | Provides superior protection against contaminants and moisture, retaining lubricant for extended service life. |
SFR6 2rs Bearing Structural Features & Performance Benefits
- Deep Groove Raceway & Single Row Design: Optimized for handling significant radial loads with high efficiency. The geometry ensures smooth rotation and low running torque.
- Full Complement Stainless Steel Construction: The rings, 7 balls (0.1563" diameter), and cage are all manufactured from stainless steel, providing excellent resistance to corrosion and enabling use in a wide temperature range from -86 to 230 °F.
- Integrated Flange & Double Rubber Seals (2RS): The flange (0.965" OD, 0.062" thick) allows for secure and straightforward axial location. The Nitrile rubber seals on both sides effectively shield the internal components from dust, dirt, and other contaminants, making the bearing suitable for harsh environments and contributing to its maintenance-free characteristics after initial lubrication.
- Precision & Clearance: Manufactured to ABEC1 tolerance class with an MC3 radial internal clearance (0.00008" to 0.0005"), ensuring consistent performance, low vibration, and reliable operation in a variety of applications.
SFR6 2rs Bearing Typical Application Areas
