|---|---|---|
| zz | Non-contact shields on both sides. | Provides effective protection against contamination while minimizing friction, contributing to the high limiting speed. |
SMF117zz Bearing Structural Features & Performance Benefits
- Compact & Robust Design: With dimensions of just 7mm bore, 11mm OD, and 3mm width, this bearing is designed for space-constrained applications. The integrated flange (OD: 12.2mm) facilitates secure and simplified mounting.
- High-Speed Capability: The combination of a stainless steel cage, non-contact shields (zz), and optimized internal geometry enables a maximum speed of 38,700 rpm.
- Corrosion Resistance: All components, including rings, balls, cage, and shields, are made from stainless steel, ensuring long-term performance in harsh or washdown environments.
- Precision Performance: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3: 0.002mm to 0.013mm), ensuring smooth and consistent operation.
SMF117zz Bearing Typical Application Areas
This bearing is ideally suited for:
- Small Precision Motors (e.g., stepper motors, DC micromotors)
- Medical and Dental Handpieces
- Office Automation Equipment (e.g., printers, scanners)
- Instrumentation and Control Devices
- Radio Control Models and Drones
