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.
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 Series
Two magnetic gears arranged at 90°. The most compact solution for right-angle power transfer in cleanroom conveyors.
Parallel Drive
CJ Series
Two coplanar gears side by side. Higher torque capacity than orthogonal — the most widely used configuration.
Mixed Drive
MGS + CJ
Combined orthogonal and parallel stages for complex multi-axis transfer paths within a single assembly.
Bevel (Cone) Drive
CS Series
Radial magnetic gear paired with an axial magnetic disc — replaces traditional bevel gears with zero-contact precision.
Face Coupling
CDS / CDQ Series
Coaxial face-to-face disc coupling. Highest torque density in the magnetic gear family, up to 28.5 N·m.
Magnetic Coupling
CI Series
Inner/outer magnet assembly with isolation shell — converts dynamic seals to static seals for zero-leakage pump and reactor drives.
Series & Specifications
Ten standard series covering every transmission configuration — sintered and bonded types, with optional SUS316L / titanium / PVC encapsulation. Torque ratings are measured at the specified air gap; all dimensions in millimetres.
Classification by Magnet Process
Sintered
NdFeB feedstock is vacuum-sintered at high temperature, then precision-machined to specification. High magnetic strength and stable performance for medium-to-high torque applications.
Bonded
Direct injection moulding — short lead time and economical. Slightly weaker than sintered types; suited to light-load, high-volume applications.
The MGS series uses sintered NdFeB rings and is the most common orthogonal (90°) drive. Two gears arranged at right angles enable shaft rotation, conveyor transfer and direction change in a compact footprint — the first choice for right-angle transfer on cleanroom lines.

CM-PE Series · Bonded, POM Clamp
The CM series uses bonded (injection-moulded) NdFeB rings — one-piece moulding, short lead time and economical, with slightly lower magnetic strength than sintered types. The POM clamp hub grips evenly without marking the shaft; ideal for light-load, high-volume orthogonal drives.

Standard parts are keyway-free with set-screw fixing; keyway or clamp fixing on request.
CDQ Series · Encapsulated Face Coupling
The CDQ series builds on the CDS with full encapsulation in stainless steel, aluminium, PVC or titanium for superior water and corrosion resistance in humid, corrosive and clean environments.
Dimension codes (values per table below)
CDQ encapsulated face coupling · standard specifications
Model code: Model code: CDQ40-12-A = encapsulated face coupling, 40 mm OD, 12 mm bore, aluminium encapsulation.
CI Series · Magnetic Coupling (Canister Type)
The CI series comprises inner and outer magnet assemblies separated by an isolation shell: the inner magnet connects to the driven part, the outer to the drive. Beyond the cushioning of a flexible coupling, it converts dynamic seals into static seals for zero leakage — widely used on chemical pumps and reactor drives.

Magnetic Circuit Design
An internal magnetic-isolation steel ring concentrates flux on the outer surface of the magnetic ring — boosting torque by 20% versus comparable products.

Pole Circuit Simulation
FEA of the multi-pole ring validates flux density and pole arrangement before tooling.

Magnetic Ring
Sintered NdFeB ring with an internal magnetic-isolation steel sleeve to redirect flux outward.

Angular Waveform
Surface flux B(G) measured vs rotation angle — sine symmetry confirms uniform multi-pole magnetisation.

Finished magnetic rotor with optimised outer-field strength for non-contact torque transfer.
How to Select
Follow these seven steps to size a magnetic gear for your application — our engineers can complete the calculation for you.
1Select the transmission direction (orthogonal / parallel / bevel / face / canister)
2Select the product type (sintered / bonded / encapsulation)
3Calculate the quantity from workpiece size and transfer distance
4Calculate the load torque
5Select the gear OD from the required torque per stage
6Select the bore size to match the shaft
7For special applications (acid/alkali resistance, sensing interference, etc.) state requirements when ordering
Handling Precautions
Depending on the spec and required torque, set the gap between 0.5–3 mm, and never below 0.3 mm.
Never re-machine the magnet section — the magnet may crack or shatter.
Avoid letting two magnetic gears strike each other — strong impacts can damage them.
The magnetic field may affect phones, magnetic cards and mechanical watches — keep them at a distance.
Non-contact transmission is not suited to very high speeds — maximum 1500 RPM.
Answers to common questions about our magnets, customisation, ordering and shipping.
What is a magnetic gear?
+
A magnetic gear transmits torque between input and output rotors via interacting magnetic fields instead of meshing teeth — contactless, lubrication-free, and inherently overload-safe (rotors slip instead of breaking teeth).
What are the advantages of magnetic gearing?
+
No physical contact means no wear, no lubrication, low noise, and overload protection; magnetic gears also isolate vibration and tolerate misalignment better than mechanical gears.
Where are magnetic gears used?
+
Typical applications include precision drives, clean/sterile environments, aerospace and robotics where lubrication-free, low-wear, overload-safe torque transmission is required.
Need a Custom Specification?
Our engineering team can customise dimensions, series, bore size, surface treatment and encapsulation material to your exact requirements.
