SCH

SCH type anti vibration mounts are made of two moulded parts . One of circular fully moulded rubber, and one circular part which is fully bonded to a centre tube which acts as a guide for the machine anchoring bolt. They are installed pre-compressed on the actual machine frame, whose thickness “E” determines the degree of pre-compression of the assembly.

Product Description

This antivibration SCH 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.

Additional Information

Operation & Assembly

The SCH mounts should be assembled according to the following installation instructions. There are two possible configurations, see previous assembly picture. They can be installed in plates of different thicknesses according to the Tmx and Tmin values given in the Table provided . The load vs deformation curves will vary according to the plate thickness in which the mount will be installed.

Washers should be used, if the rubber surface is not covered with the contact surface.
