Torsionally-flexible, shear type coupling
Intermediate spacer in standard length
Easy exchange of elastomer elements in assembled state
Use particularly in pump industry and for compressors
The POLY coupling is a torsionally-flexible, shear shaft coupling for general machinery. It is assembled by axially plugging the hubs into each other and has excellent dampening characteristics. Its unique features are the flexible elastomeric elements that are located in both coupling halves.
The coupling consists of 2 hubs with fingers that are separated by elastomeric elements which are assembled by axial blind plug-in to each other. Elastomer elements are placed into the slots of both coupling hubs. Torque is transmitted in a compact design. Shaft misalignments, vibrations and shock loads are effectively absorbed by the POLY coupling.
The coupling is maintenance-free and used in general machinery, the pump industry and in compressors. The Poly coupling handles torque ranges of up to 65,000 Nm and is stocked in 21 different sizes and3 designs for immediate availability. In addition to our standard coupling models, a variety of flange, drop out center and spacer options are available.
The coupling can be adapted to many applications due to the many options that are possible with the building block arrangement. The POLY components of a given model can be mixed and matched with each other to obtain different shaft distances using the same basic component.
This type is certified and confirmed according to directive 2014/34/EU as unit of category 2G/2D and thus suitable for the use in hazardous areas of zone G1, G2, D21 and D22.
