BSB Vibration Isolators

Captive vibration isolators providing an excellent balance of vibration isolation, stability and motion control, with integral fail-safe restraint.

The AMC-MECANOCAUCHO® BSB vibration isolators are captive elastomeric mounts designed to work in both compression and shear, providing an optimal balance between vibration isolation and equipment stability.

Their design provides effective control of vertical and horizontal movement, making them particularly suitable for machinery subjected to dynamic forces or applications requiring a more stable suspension. An integral fail-safe restraint provides mechanical retention of the equipment in the event of tensile forces, shock or excessive displacement.

Available in a wide range of sizes and rubber hardnesses, BSB vibration isolators cover a broad range of loads. They are particularly suitable for engines, generator sets, pumps, compressors, rotating machinery and mobile equipment requiring a combination of effective vibration isolation, good stability and mechanical restraint.

Technical characteristics

The top metal hood protects the rubber from the Ozone, UV rays, diesel or oils which may cause major damage to the rubber.
The metal parts have a suitable anticorrosive treatment for outdoor applications. RoHs compliant.
They have an interlocking metal component that provides a fail-safe protection for mobile applications. This device limits vertical movement when the mounting is submitted to shock inputs.
The mounts are clearly identified, as the baseplates are engraved with the type and hardness, which makes it possible to easily recognise the part even after several years of use.
The hood has a cross stamped on the top, which enhances its stiffness on mobile applications and also improves the evacuation of oils or liquids that splash onto it.

Operation and Assembly

RECOMMENDATIONS FOR HOOD MOUNTS

The hood mounts should be be installed between two parallel and perfectly flat surfaces. Mounts operating tilted or twisted do not work properly. This may be due to incorrect alignment, tolerances in the building of the chassis or over-tightened torque during the installation of the Antivibration mounts.

This applies to our marine-type, BSB, BRB or Mecanodamp mounts.

Advantages

01

Easy installation

This mount requires no major modifications to the structure for installation.

02

High protection against weathering and chemical contamination

The bell housing protects the rubber from ozone and UV radiation, while also preventing contact with diesel, oils, or other chemicals that could damage it.

03

Mount offering high stability

Suspensions built with this mount barely move, thanks to a geometry designed to control the movement of the suspended element.
