EVOLASTIC® EH/EHP

Elastomer with radial hub for various applications
The coupling type EH/EHP consists of a highly flexible individual element and a radial hub. This type is suitable for versatile application in frequency-controlled and I. C.-engine drives. Subject to its torsionally soft property it serves for insulating vibrations and acoustics in the drive train.
 
In addition to transmitting the torque the coupling compensates for axial, radial and angular misalignment while absorbing overload flexibly.
 
The radial hub is available as type 1.0 (feather keyway and setscrew), 3.0 (spline toothing) and 3.1 (spline/clamping hub N).
 
Type EH can be screwed in axially and is available in ten sizes.
Type EHP can be plugged in axially and is available in seven sizes.
 
Both types are available in two materials - NR and on request EPDM.
The maximum operating temperature of the element is 90 °C (NR) resp. 110 °C (EPDM).

Additional Information

The key component of the series is a vulcanised, circularly closed elastomer element made of natural rubber  (WN, SN, MN, up to  90 °C) or for higher temperatures made of synthetical EPDM material (WE, SE, ME, up to 110 °C).
 
The different kinds of rubber hardness cover one application and torque range per size. The designing principle ensures a precise prestress in the elastomer.
