SMR62zz Bearing Product Overview & Core Advantages
The SMR62zz is a miniature deep groove ball bearing designed for applications demanding compact size, reliable performance, and corrosion resistance. Constructed entirely from stainless steel, it is ideally suited for high-precision and high-reliability scenarios where space is limited. Its primary function is to support radial loads efficiently, offering a robust solution for small-scale mechanisms. The inclusion of shielded seals (zz) helps protect the bearing's interior from contaminants, enhancing its operational lifespan.
SMR62zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SMR | Manufacturer series designation for miniature bearings. |
| 62 | Standard dimension series code, defining the bearing size relationship (bore: 2mm, OD: 6mm, width: 2.5mm). |
| zz | Signifies the bearing is equipped with shielded seals on both sides. This provides protection against dust and other particulates while allowing for high-speed operation. |
SMR62zz Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a bore diameter of 2 mm and a total weight of just 0.33 g, this bearing is engineered for applications where minimizing size and mass is critical.
- Corrosion Resistance: All components, including rings, balls, and cage, are made from stainless steel, making it suitable for use in harsh or wash-down environments.
- Radial Load Capacity: The single row deep groove construction is optimized to handle radial loads effectively, with a dynamic load rating of 57 lbf and a static load rating of 16 lbf.
- High-Speed Capability: The stainless steel cage and optimized internal geometry contribute to a high limiting speed of 67,500 rpm, qualifying it as a high-speed bearing in its class.
- Precision & Reliability: Manufactured to ABEC1 tolerance class with a controlled MC3 radial internal clearance (0.002mm to 0.013mm), ensuring smooth and consistent operation.
SMR62zz Bearing Typical Application Areas
This miniature precision bearing is commonly found in:
