CB Vibration Isolators
Pair-mounted anti-vibration mounts providing high radial elasticity, protection against elastomer fatigue and excellent resistance to dynamic loads.
The AMC-MECANOCAUCHO® CB Vibration Isolators are designed to be installed in pairs, on either side of the chassis or structure to be isolated. Installation is simplified by using a single through-bolt, with washers positioned at both ends of the assembly.
The CB Vibration Isolators incorporate metal reinforcement in the radial working area, preventing direct contact between the elastomer and sharp edges around the mounting holes, particularly when these are produced by laser cutting. This design helps to reduce stress concentrations and elastomer fatigue.
It also allows simple mounting holes to be used without requiring machined radii or chamfers, simplifying assembly and helping to reduce manufacturing and installation costs.
Thanks to their high radial elasticity and multidirectional bump-stop behavior, CB Vibration Isolators provide effective vibration isolation and shock absorption while limiting excessive movement. They are particularly suitable for mobile machinery, cabs, off-highway equipment and applications subjected to high dynamic loads.
Technical characteristics
- The AMC-MECANOCAUCHO® CB mounts are radially more flexible tan axially. This feature is especially interesting for those machines or equipment where radial axis vibration isolation is important.
- The mount is provided with a built in multi-directional snubbering system that limits the maximum allowed displacements.
- Different sizes and hardness are available to accommodate applications from 4kg to 800kg per mount.
- Metal parts are embedded in rubber in order to prevent corrosion.
The CB 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.
- 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.
| The vibration isolators AMC-MECANOCAUCHO® have a double-bonded design, which makes them suitable to withstand high dynamic forces. The dome-shaped rubber design of this vibration isolator allows progressive rigidity in the event of an overload. This fact allows to limit the movement of the suspended element. Symmetric stiffness is achieved using 2 pieces that are vertically opposite. One is installed supporting the load and the other is supporting the rebound forces. |

| The following graph shows the typical deformation behavior of the part under compressive and tensile loads. |
|
| The following picture shows, in a finite element model, how the mount behaves when it is loaded and it makes contact with the snubber. |
|
| They are ideal to be used in mobile applications that are exposed to compressive and tensile forces, for example, on-board mounting of equipment on ships, cabins, road transport such as motors, pumps, generator sets. |
|
| They can also be used, thanks to their design, to isolate electrical cabinets suspended, both as stabilizers working under compression/tension loads or in shears with a durable and stable rigidity over time. |
