Non-contact magnetic couplings for hermetic, leak-free torque transmission. No dynamic seal, no leakage path, no contamination risk. Disc, barrel and synchronous geometries. Specified for chemical, pharmaceutical, food, semiconductor and medical applications.
Two magnet discs on parallel shafts with a separating can. Axial torque transfer, common in pumps and mixers.
Cylindrical magnets on inner and outer parts. Higher torque capacity, hermetic seal.
Synchronous torque transmission with no slip. Used in precise positioning applications.
Representative magnetic couplings showing magnet layout, containment shell and hub interface.

Packing A magnetic coupling is selected around torque, speed, air gap, temperature, containment and upset conditions. The magnet set is only one part of the hermetic torque path.
A drawing alone may not define the magnetic requirement. These inputs help us recommend the right grade, geometry, coating and inspection plan instead of quoting a generic part.
Provide continuous, peak, startup and stall torque, speed range, acceleration, duty cycle and the driven fluid or load.
Define pressure, vacuum, leakage criterion, fluid chemistry, temperature, cleanability and the containment material requirement.
Share shaft, flange, bearing, can, air-gap and mounting dimensions, plus allowable misalignment and runout.
Describe dry run, blocked shaft, thermal runaway, loss of synchronization, reverse rotation and maintenance conditions.
Inspection scope should follow the failure mode. We can align the report format, sample quantity and release criteria during drawing review.
Test the coupling across the agreed speed and torque range, including startup, transient and thermal conditions.
Use the specified leak, pressure, cleanliness or sterilization method on the final process boundary.
Measure magnet, can, bearing and process-side temperatures under representative load and speed.
Verify concentricity, axial position, air gap and shaft alignment because mechanical error reduces torque margin.
It transfers torque across a sealed boundary without a dynamic shaft penetration, which can reduce leakage paths and contamination risk when the complete system is designed and validated correctly.
Start with continuous and peak torque, speed, duty cycle, temperature, air gap, process pressure and fluid properties. Startup, stall and transient conditions are essential for selecting margin.
Material selection depends on pressure, stiffness, chemical compatibility, temperature, permeability, eddy-current loss and manufacturing method. The can should be reviewed as a system component, not chosen separately.
Our engineering team can review material, operating conditions, magnetic requirements, manufacturing route and validation needs before quotation.
