Magnetic Gear
磁传动齿轮
Magnetic Gears transmit torque through the attraction and repulsion of permanent magnets — no physical contact, no friction, no wear particles. Designed for cleanroom production lines (LCD, PDP, PCB, TFT, OLED, Solar Cell) and vacuum chambers where even microscopic contamination is unacceptable, they are a direct replacement for conventional mechanical gears.
Built with sintered NdFeB rare-earth magnets, our MGS / CJ / CS / CDS series deliver industry-leading torque density with virtually zero acoustic output. A built-in torque-limiting function means unexpected overloads cause the gears to slip rather than break — protecting both the gear and the driven equipment.
We offer five transmission configurations — orthogonal (90°), parallel, bevel (cone), coaxial face coupling, and magnetic shaft coupling — covering the full range of industrial motion transfer requirements. Corrosion-resistant variants with stainless-steel (316L), titanium, or PVC encapsulation are available for chemical, pharmaceutical, and food-processing applications.
Key Features
Dust-Free
Non-contact transmission generates zero wear particles — ideal for ISO Class 1 cleanrooms.
Ultra-Low Noise
No meshing teeth means virtually silent operation, improving cleanroom working conditions.
Torque Limiting
On overload, gears slip automatically — no mechanical damage, no production stops.
Vacuum Compatible
Operable down to 10⁻⁵ Pa with low outgassing special surface treatments.
Maintenance-Free
No contact surfaces to wear means unlimited service life and zero spare parts cost.
Corrosion Options
SUS316L, titanium or PVC encapsulation available for harsh chemical environments.
Product Classification
Magnetic gears are classified into six main types by transmission direction and structural form:
Orthogonal Drive
MGS SeriesTwo magnetic gears arranged at 90°. The most compact solution for right-angle power transfer in cleanroom conveyors.
Parallel Drive
CJ SeriesTwo coplanar gears side by side. Higher torque capacity than orthogonal — the most widely used configuration.
Mixed Drive
MGS + CJCombined orthogonal and parallel stages for complex multi-axis transfer paths within a single assembly.
Bevel (Cone) Drive
CS SeriesRadial magnetic gear paired with an axial magnetic disc — replaces traditional bevel gears with zero-contact precision.
Face Coupling
CDS / CDQ SeriesCoaxial face-to-face disc coupling. Highest torque density in the magnetic gear family, up to 28.5 N·m.
Magnetic Coupling
CI SeriesInner/outer magnet assembly with isolation shell — converts dynamic seals to static seals for zero-leakage pump and reactor drives.
