SCH Vibration Isolator

Compact two-piece vibration isolator, installed under pre-compression in the chassis to provide multidirectional vibration isolation and limit movement under tension and compression.

The AMC-MECANOCAUCHO® SCH Vibration Isolators consist of two rubber elements which, once assembled, form an elastic connection between the equipment and the chassis. The lower element incorporates an internal metal sleeve that guides the mounting bolt and ensures accurate tightening of the assembly.

The isolator is installed directly into a hole in the chassis. During tightening, the two rubber elements are pre-compressed, allowing the isolator to perform effectively in multiple directions and withstand both compressive and tensile loads.

The level of pre-compression is determined by the chassis thickness “T”, providing controlled elastic behavior and limiting equipment movement under dynamic loads.

Thanks to their compact, simple and robust design, SCH Vibration Isolators are particularly suitable for cabs, enclosures, auxiliary equipment and mobile machinery requiring effective vibration isolation and direct integration into the chassis.

Technical characteristics

This antivibration mount is ideal for applications with major dynamic loadings such as : Off Road Construction vehicles for engines , gearboxes , Operator Cabins where movement control is necessary. It also offers optimal stability, as well as good attenuation of impacts and high frequency vibrations.

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.
