SR2-6zz Bearing Product Overview & Core Advantages
The SR2-6ZZ is a precision miniature ball bearing designed for applications demanding high reliability in compact spaces. As a single row deep groove ball bearing with shielded construction, it excels at handling radial loads and is manufactured to ABEC1 precision tolerances. Its all-stainless steel construction, including the cage and shields, provides excellent corrosion resistance, making it suitable for a wide temperature range from -86 to 230 °F. This bearing is an ideal solution for high-speed, low-torque applications requiring consistent performance.
SR2-6zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SR2-6 | Indicates the bearing series and size designation in inches. |
| ZZ | Signifies that the bearing is equipped with shields on both sides. These non-contact shields protect against contamination from solid particles while minimizing friction. |
SR2-6zz Bearing Structural Features & Performance Benefits
- Robust Load Capacity: The deep groove raceway and optimized geometry enable efficient handling of the specified radial dynamic load rating of 110 lbf.
- High-Speed Performance: The combination of a stainless steel cage, precision-ground components, and low-friction shields contributes to a high limiting speed of 47,700 rpm.
- Corrosion Resistance & Longevity: The use of 300 series stainless steel for all critical components ensures reliable operation in harsh or washdown environments, enhancing service life.
- Precision Operation: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3), this bearing provides smooth and quiet running, essential for sensitive applications.
SR2-6zz Bearing Typical Application Areas
This bearing is commonly specified in:
- Small Precision Motors (e.g., drones, miniature DC motors)
- Medical and Dental Handpieces
- Office Automation Equipment (printers, scanners)
- Instrumentation and Control Devices
- Radio-Controlled Models and Hobbyist Applications
