SMF62zz Bearing Product Overview & Core Advantages
The SMF62zz is a miniature single row deep groove ball bearing designed for applications requiring compact dimensions and reliable performance. This metric stainless steel bearing features shielded construction for contaminant protection and is engineered to handle primarily radial loads with high precision. Its small footprint, with a 2 mm bore and 6 mm outside diameter, makes it ideal for space-constrained, high-speed mechanisms. Manufactured to ABEC1 tolerance class, it delivers consistent performance and long service life in demanding environments.
SMF62zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SMF62 | Basic bearing designation, indicating a specific miniature bearing series with a 2 mm bore and 6 mm outside diameter. |
| zz | Denotes non-contact shields on both sides. This provides effective protection against dust and other contaminants while minimizing friction, contributing to the high limiting speed. |
SMF62zz Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of a stainless steel cage, six precision balls, and non-contact shields enables a high limiting speed of 67,500 rpm, making it suitable for high-rotation applications.
- Corrosion Resistance: All critical components, including rings, balls, and cage, are manufactured from stainless steel, ensuring excellent resistance to corrosion and suitability for harsh environments.
- Radial Load Capacity: Engineered to handle radial dynamic loads up to 57 lbf and static loads up to 16 lbf, providing reliable support in compact assemblies.
- Precision Performance: Built to ABEC1 precision class with a controlled MC3 radial internal clearance (0.002mm to 0.013mm), ensuring smooth and quiet operation with minimal runout.
- Compliance & Reliability: The bearing is ROHS and REACH compliant, meeting international environmental and safety standards for a wide range of industrial uses.
