SCHR Vibration Isolator

Reinforced SCH vibration isolator with metal reinforcement around the mounting hole, providing increased durability under dynamic loads and protecting the elastomer against fatigue caused by friction with the frame.

The AMC-MECANOCAUCHO® SCHR vibration isolators consist of two rubber elements, one of which incorporates an internal metal sleeve to guide the mounting bolt.

The isolator is installed directly into a machined hole in the frame. When tightened, the rubber elements are pre-compressed, with the frame thickness “T” determining the level of pre-compression and ensuring a stable and secure installation.

Compared with the standard SCH vibration isolator, the SCHR incorporates metal reinforcement around the mounting hole, protecting the elastomer against fatigue caused by friction with the frame. This design improves the durability of the isolator, particularly in applications subjected to vibration, shock and repeated dynamic loads.

To ensure correct operation, the frame thickness T and mounting hole diameter must comply with the values specified in the technical table.

Technical characteristics

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.
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.

Advantages
01
Easy installation
This mount requires no major modifications to the structure for installation.
02
Mount offering high stability
Suspensions built with this mount barely move, thanks to a geometry designed to control the movement of the suspended element.
03
High robustness in dynamic applications for improved durability
These mounts offer enhanced robustness and are designed to withstand extreme load peaks. They are especially recommended when good durability is required in demanding applications.
