Swelling sets type fasteners DML Series Precision Diaphragm Flexible Coupling,flexible couplings used on machinery.

1, the coupling type of the friction torque limiter, when overload occurs, frictional slipping produced by active and passive side

2, incidental flexible coupling can absorb the deviation of axial, radial and angular during installation process
3, overload slip torque can be adjusted by nuts or bolts in a certain range as stepless setting overload skid still have larger residual torque, so the sliding time shoulds not be too long, it’s suitable for intermittent, impact overload situations.

4, relative to other forms of torque limiter, the price is more economical and practical.
5, using environment temperature: - 30 °C ~ 110 °C.
