SR2-6 Bearing Product Overview & Core Advantages
The SR2-6 is a precision miniature ball bearing designed for demanding applications requiring high reliability and consistent performance. As a single row deep groove ball bearing in an inch series, it excels in handling radial loads efficiently. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. Its compact design, with a 1/8" bore, makes it an ideal choice for applications where space is limited and precision is paramount, such as in small instruments and precision mechanisms. The bearing conforms to ABEC1 precision class standards, ensuring smooth operation and reliable performance.
SR2-6 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SR2-6 | Standard model designation for a specific series of miniature inch bearings. |
| (No Suffix) | Indicates an open (unsealed) bearing construction. Lubrication is required by the user for operation. |
SR2-6 Bearing Structural Features & Performance Benefits
- Robust Construction: The single row deep groove raceway and complement of 7 balls provide a robust design capable of handling the specified radial dynamic load rating of 110 lbf.
- High-Speed Capability: With a limiting speed of 47,700 rpm, this bearing is engineered for high-speed operation, making it suitable for small motors and high-RPM spindles.
- Precision & Stability: Built to ABEC1 tolerance class with a controlled radial internal clearance (MC3 group: 0.00008" to 0.0005"), ensuring consistent performance and minimal vibration.
- Corrosion Resistance: All components, including rings, balls, and cage, are made from stainless steel, providing protection in harsh environments and a wide operating temperature range from -86 to 230 °F.
- Compact and Lightweight: With an overall weight of just 0.96 grams and a compact cross-section, it minimizes inertia and saves space in precision assemblies.
