SMF62 Bearing Product Overview & Core Advantages
The SMF62 is a metric miniature deep groove ball bearing engineered for precision applications requiring compact design and reliable performance. Constructed entirely from stainless steel, it offers excellent corrosion resistance. As a single row, open type bearing, it is primarily designed to handle radial loads efficiently. Its small bearing dimensions (2mm bore, 6mm OD) and integrated flange for secure mounting make it ideal for space-constrained, high-precision assemblies demanding consistent operation and long service life.
SMF62 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SMF62 | Standard model number for a specific series of miniature flanged bearings. |
| Open (No Seal/Shield suffix) | Indicates the bearing has no integral seals or shields, allowing for higher limiting speeds and facilitating custom lubrication schemes. |
SMF62 Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With a total weight of only 0.34 g and a minimal cross-section, it is perfect for miniature mechanisms and portable devices.
- Integrated Flange: The flange (7.2mm OD) simplifies mounting and positioning, providing axial location and enhancing assembly rigidity.
- High-Speed Capability: The open design and stainless steel cage contribute to a high limiting speed of 67,500 rpm, suitable for demanding high-speed applications.
- Precision Performance: Manufactured to ABEC1 tolerance class with a controlled MC3 radial internal clearance, ensuring smooth and quiet operation.
- Corrosion Resistance: All components, including rings, balls, and cage, are made from stainless steel, making it suitable for harsh environments and cleanroom applications.
SMF62 Bearing Typical Application Areas
This miniature bearing is commonly used in:
- Precision Instruments and gauges
- Small DC Motors and stepper motors
- Medical devices and dental handpieces
