SMF105zz Bearing Product Overview & Core Advantages
The SMF105zz is a metric miniature ball bearing featuring a single row design and stainless steel construction. Engineered for radial load applications, it offers excellent corrosion resistance and reliable performance in compact spaces. Its shielded (ZZ) design provides effective contamination protection while maintaining low friction, making it ideal for applications demanding high precision and long service life.
SMF105zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SMF105 | Bearing series designation, indicating a flanged miniature bearing with a 5 mm bore diameter. |
| zz | Denotes shielded on both sides. This provides protection against contaminants while allowing for high-speed operation compared to contact seals. |
SMF105zz Bearing Structural Features & Performance Benefits
- Compact & Lightweight Design: With dimensions of 5x10x4 mm and a weight of only 1.38 grams, it is perfect for space-constrained applications.
- Enhanced Contamination Protection: The stainless steel shields (ZZ) help retain lubrication and exclude dust and debris, extending bearing life.
- Corrosion Resistance: All components, including rings, balls, and cage, are made from stainless steel, making it suitable for harsh environments and washdown applications.
- Precision Performance: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3), ensuring smooth and consistent operation.
- Integrated Flange: The flange (outer diameter 11.6 mm) simplifies mounting and positioning, providing secure axial location.
SMF105zz Bearing Typical Application Areas
- Small Precision Motors (e.g., stepper motors, DC motors)
- Medical and Dental Equipment (e.g., handheld tools, pumps)
- Office Automation Equipment (e.g., printers, scanners)
- Robotics and RC Models (e.g., joints, drive wheels)
- Instrumentation and Measurement Devices
