Description

 

  • Lubricating oil is unnecessary because the Jac disc coupling has no sliding, frictional, or moving parts.
    Therefore, there is no friction or noise, and energy loss is low, with no dirty oil to cope with.

  • Higher torsional and no backlash.
    For equipment such as machine tools with numerical controllers, indexing system, and printing machines requiring accruate shaft rotation and phase control, Jac disc coupling are best suited because of their high torsional stiffness.

  • When properly installed and if initial conditions remain unchanged, Jac disc coupling have an unlimited service life.
    Required maintenance consists of visual inspection or the condition of the element(flexible plate) and of the bolts and nuts when operation is stopped.
    Should the element be damaged due to overload or accident, a fall-safe mechanism transmitting rotation via washers becomes operational.
