SMR106zz Bearing Product Overview & Core Advantages
The SMR106zz is a miniature deep groove ball bearing engineered for precision applications requiring compact dimensions and reliable performance. Constructed entirely from stainless steel, it offers excellent corrosion resistance. As a single row, shielded bearing, it is primarily designed to handle radial loads efficiently. Its small bearing size (6x10x3 mm) makes it ideal for space-constrained assemblies, while the integrated shields help retain lubrication and exclude contaminants, contributing to its longevity and suitability for high-speed operations up to 40,500 rpm.
SMR106zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| SMR | Manufacturer Series Prefix | Denotes a specific family of miniature stainless steel bearings. |
| 106 | Size Designation | Specifies the bore diameter (6 mm), outside diameter (10 mm), and width (3 mm). |
| zz | Shield Type | Indicates the bearing is fitted with shields on both sides. This provides protection against large particulate contaminants while maintaining low friction for high-speed capability. |
SMR106zz Bearing Structural Features & Performance Benefits
- Full Stainless Steel Construction: The rings, balls, and cage are manufactured from stainless steel, providing superior corrosion resistance and making the bearing suitable for harsh environments and washdown applications.
- Deep Groove Raceway: The geometry of the deep groove raceway is optimized to support significant radial loads and moderate axial loads in both directions.
- Shielded Design: The non-contact ZZ shields help to retain lubricant within the bearing and protect the internal components from dust and debris, enhancing operational life without significantly increasing rotational torque.
- Precision Engineering: Manufactured to ABEC1 tolerance class, this bearing ensures consistent running accuracy and smooth operation, which is critical for precision instruments.
- Optimized Internal Clearance: The standard MC3 radial internal clearance (0.002mm to 0.013mm) is suited for most general applications, providing a balance between quiet operation and thermal expansion management.
SMR106zz Bearing Typical Application Areas
The SMR106zz is a versatile component found in a wide range of compact and precision devices, including:
- Small Electric Motors: Used in drones, RC models, and small cooling fans.
- Precision Instruments: Ideal for optical encoders, medical devices, and laboratory equipment.
- Office Automation: Employed in printers, scanners, and copiers.
- Food and Beverage Equipment: Its stainless steel construction is suitable for applications requiring corrosion resistance and cleanability.
