AMC Mecanocaucho

The AMC-Mecanocaucho® SCHR type mounts are made of two parts of rubber, one of which bears an inside metal bushing which acts as a guide through the machine anchoring screw. It is installed pre-compressed on the actual machine frame, whose thickness “T” determines the degree of precompression.

Moreover it contains a metallic part, that avoids a premature wear by friction between the rubber and the housing of the mount.

Technical characteristics

This antivibration mount is ideal for applications of major dynamic loads where movement control is necessary, such as in the cabins of all types of mobile vehicles. It also offers optimal stability, as well as good attenuation of impacts and vibrations.

Applications

Vehicle cabins
Public works and agricultural vehicles, etc.

Operation and Assembly

The SCH mounts must be installed according to the following installation instructions:

They can be installed in frames of different thicknesses according to the values of T, given in the table below. The load vs. Deformation curves will vary depending on the thickness of the frame on which the mount is installed. This thickness "T" determines the degree of precompression of the mount.
For the correct installation of the mount, it is recommended to make a hole in the frame with diameter Q, given in the table below.
It is recommended to chamfer the hole so as not to damage the rubber.
The use of washers is recommended in the event that the support surface does not completely cover the rubber surface.
Respect the tightening torque of the mount.
In case of any doubt, contact the technical department.

There are two possible configurations, see assembly 1 and assembly 2, for which the recommendations given in the following chart must be observed.

They can be installed in plates of different thicknesses according to the Tmax and Tmin values given in the table at the bottom.

The Load vs. Deformation curves will vary according to the thickness of the plate on which the mount is to be installed.
