The Jac Wire drum coupling is designed for installation in drum drive
of crain and conveying system.
The Wire drum coupling can be used in the very difficult and rough
operating conditions of iron and steel works and continuos heavy
load operation in shore cranes.
With compact design and capable of transmitting large radial load,
enjoy longer life and minimum loss of power angular misalignment
can be allowed up to 1.5˚.
With design of decreasing slip movement of rollers by construction
of minimum backlash between crowned rollers and cylindrical bores,
the relative movement between rollers and bores, which is cause of
wear, is considerably reduced due to the natural movement of drum
In the transmission of power, a stamping hardness of the rollers
profile is produced, with which higher wear resistence is achieved
