SFR166zz Bearing Product Overview & Core Advantages
The SFR166zz is a single row deep groove ball bearing designed for high-performance applications requiring reliable operation and compact design. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. Its key advantage lies in its ability to handle radial loads efficiently, making it a robust and durable solution for precision machinery. The inclusion of integral shields (zz) protects against contamination, enhancing its operational lifespan and reliability in demanding environments.
SFR166zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SFR | Manufacturer series designation for miniature and instrument bearings. |
| 166 | Specifies the bearing size, corresponding to a bore diameter of 0.1875" and an outside diameter of 0.375". |
| zz | Indicates the bearing is equipped with shields on both sides. This provides protection from solid contaminants while allowing for higher limiting speeds compared to contact seals. |
SFR166zz Bearing Structural Features & Performance Benefits
Robust Stainless Steel Construction: All components, including the rings, balls, and cage, are made from stainless steel, providing superior corrosion resistance and durability, suitable for a wide temperature range from -86 to 230 °F.
Optimized Load Capacity: The deep groove raceway and complement of 8 precision balls enable efficient handling of the specified radial dynamic load (122 lbf) and radial static load (44 lbf).
Shielded for Contamination Protection: The non-contact stainless steel shields help retain lubricant and exclude larger contaminants, contributing to consistent performance and a longer service life. Note: Lubrication is required for optimal operation.
Precision and Speed: Built to ABEC1 tolerance class with a controlled radial internal clearance (MC3), this bearing ensures smooth, quiet running and is capable of operating at a limiting speed of 45,000 rpm.
SFR166zz Bearing Typical Application Areas
The SFR166zz is ideally suited for applications requiring compact size, corrosion resistance, and reliable performance. Common uses include:
- Precision Instruments and medical devices
- Small electric motors and gearboxes
- Office automation equipment and computer disk drives
- Robotics and miniature machinery
- Food processing and chemical handling equipment (due to stainless steel construction)
