What difference between disc type couplings and co-axial type magnetic couplings ?

Magnetic disc vs co-Axial coupling comparison
Coupling style	Magnetic disc couplings ( CDS )	Co-axial magnetic couplings ( CI )
Permanent-magnetic	√	√
Contactless	√	√
Maintenance-free	√	√
Torsionally flexible	√	√
Low vibrations	√	√
Material	SUS304 (custom SUS316,PVC available)	SUS304 (custom SUS316,PVC available)
Containment shroud	None	Optional
Axial forces	High axial force which must be restrained	Coupling finds its own center with ~0 axial force
Shaft fixing method	Small size type A, big size type B & C available	Type B
Slip torque adjustment	Air gap can be adjusted to increase or decrease slip torque	Coupling hubs can be seperated axially to decrease slip torque (axial force will result)
Angular misalignment capacity	3° Max	Ensure coupling hubs (or barrier if used) do not contact
Parallel misalignment capacity	6.35mm (0.25in) Max	Ensure coupling hubs (or barrier if used) do not contact
Containment barrier	Simple flat barrier	Top-hat shaped barrier
Maximum torque [N.m]	18.5N.m	84N.m
Max. pressure resistance [bar]	Up to 80 bars depending on size	Up to 90 bars depending on size
Max. temperature resistance [°C]	150/300 depending on magnet material	150/300 depending on magnet material
