Linear Magnetic Couplings are simpler compared with torque couplers. It can be two magnets or comprised of engineered arrays containing multiple magnets of various configurations. The required coupling force and the operating environment are the prime design variables.
Linear Magnetic Couplings Part No.: HSLNMC
Material: NdFeB, SmCo, AlNiCo
Shape: Custom
Dimension: Custom

Tubular – these types of
permanent magnetic couplings are configured so that one member of the coupling is fully nested within the ID of the second member. The two components share a common axis about which both translate.
Axial misalignment – Tolerant.
Inherently, linear couplings align axially. As such, any misalignment will lead to the driver pulling the follower into position.
Radial misalignment – Tolerant.
The amount of tolerance is based on the spacing between the driver and follower. The larger the spacing, the greater the tolerance to radial misalignment. Large radial offsets in closely spaced coupling may lead to excessive radial loads on bearings or shafts.
Angular misalignment – Tolerant
The amount of tolerance is based on the spacing between the driver and follower. The larger the spacing, the greater the tolerance to angular misalignment.
Planar – these types of magnetic couplings are configured so that the magnetic flux is transferred about the flat end faces of the magnetic assembly. The two components are attracted to one and other and typically require additional thrust bearing support for proper integration.
Planar (direction of motion) misalignment – Tolerant.
Inherently, linear couplings align axially. As such, any misalignment will lead to the driver pulling the follower into position.
Planar (perpendicular to direction of motion) misalignment – Very tolerant
Designs can be produced to constrain 2-DOF if required
Angular misalignment –Tolerant
The amount of angular misalignment depends on the air gap between the two members
Similar to a torque couple, a Linear Coupler relies on magnetic interaction between two coupler halves. As in the torque coupler, usually one Half is the driver and the other Half is the follower. Linear couplers are often simpler to design and to construct when compared to torque couplers because the movement is linear and non-rotational.

Magnetic Couplings can be as simple as two magnets or comprised of engineered arrays containing multiple magnets of various configurations. The operational gap between the coupler’s halves, the required coupling force, and the operating environment are the prime design variables.
