NEW CB 125. A FAILSAFE VIBRATION ISOLATOR WITH VERTICAL SYMMETRIC STIFFNESS AND MULTIAXIAL SNUBBER WITH HIGH SPEC CORROSION PROTECTION.
Its specific design allows very similar traction and compression stiffness rates. This feature is particularly useful on those applications where vibration and transient forces are coming from multiple axis and a constant natural stiffness is required. The metal parts are robust and can be supplied with a washer that acts as a fail-safe device to resist traction forces. Empty air slots allow lower natural frequencies in vertical and horizontal Stiffness.

Equipped with built in axial and radial buffers, these vibration isolators can provide high stability suspended elements. Metal parts treated with Zinck Nickel coating + covered with rubber. This feature allows them to have high protection to salt spray test chamber. |

TECHNICAL CHARACTERISTICS
The AMC-MECANOCAUCHO® type CB-125 vibration isolators have a double bonded design to withstand to high dynamic forces. The dome shaped rubber design of this vibration isolators allows a progressive stiffness when overloading.The symmetric stiffness is achieved with 2 pcs that are vertically opposite. One is installed supporting the load and the other is supporting rebound forces. The graphic below shows the typical load deflection behavior in compression and tension.

Compared to the CB 130 support, the CB 125 offers a very similar axial stiffness. However, its radial stiffness is reduced. In this radial direction, the elastic stroke is also increased, and this makes the CB 125 an interesting support for applications where it is necessary to isolate not only axial (vertical) but also radial (horizontal) excitations.
As an example, see below the comparison between the CB 130 in 70Sh and the CB 125 in 75Sh, both for the vertical and horizontal directions.
As can be seen, the axial stiffness is very similar (with a difference of 5Sh in the rubber hardness) however the CB 125 offers a greater radial elastic stroke. Therefore it is less stiff in this direction.
APPLICATIONS
The AMC-MECANOCAUCHO® type CB-125 vibration isolators are used on mobile applications that are exposed not only to compression and traction forces but also radial efforts. For example, mounting on board equipment in ships, rail, road transport such as engines, pumps, generator sets, or even tractor cabs.
