Type DF 1 to 23,000 Nm

DF torque limiters prevent machine damage from jamming and overloads and so they reduce maintenance and downtime. They are simple to use, low cost, silent, bi-directional and steplessly adjustable.

UK stocks for fast delivery of popular models up to 950 Nm.

On overload DF torque limiters slip and absorb shock loads. At lower speeds they can be used as slipping clutches for extended periods.
