SINULASTIC type B highly flexible flange coupling | KTR

SINULASTIC® highly flexible flange couplings for versatile applications 

KTR SINULASTIC is a modularly structured series of highly flexible flange couplings based on a disk-shaped coupling body. Four practical basic versions with individual properties cover a wide range of applications primarily for diesel engine drives, but also general drive tasks.

By using different elastomer materials, this coupling series can be used in applications of up to + 130°C ambient temperature.

Applications of the highly flexible flange coupling SINULASTIC:

The main task of the coupling is reducing torsional vibrations resulting from excitations of the I. C.-engine during standard operation and misfire operation as well as protecting the drive from overload.

It is a good option both for variable speed and constant speed drives, while a supercritical selection of the drive train above resonance level is made. Particularly for the series the coupling disk requires smallest possible axial mounting space. 

Depending on the type the coupling is pluggable and compensates for displacements resp. tolerances moderately to very well.

It is a non-slip or shear type and radially mountable.
