Vibration isolation systems & technology
Select Llanguaje


A flexible bush Silentflex® (as know as Silentblock®) has a rubber element enclosed between two metal sleeves. It's conceived to replace a greased bush when is necessary to limit vibration, wear and noises in mechanic assemblies.


The bush is characterized by the permissible:

Radial static force and a corresponding eccentricity

Maximum torsion angle α and a corresponding compensating torque

Axial load and a corresponding elastic displacement

Conical angle and a corresponding compensating torque




These flexible rubber to metal bushes are excellent as shock absorbers and high frequency vibration isolation elements, also to reduce friction and eliminate play between moving parts. Are used in mobile appliances and machines or between mechanic parts that shall be flexible in relation to each other. Are generally installed for all types of assembly must withstand axial thrust, radial, torsion or conical, advantageously replacing the hinges.


In automotive are used at both ends of the shock absorbers as excellent components for suspension bushing, to support combustion engines in vehicles, vibrating tables, construction machinery, industrial machinery (milling machines, lathes, drilling, etc.), military vehicles, food industry, cutting granite machines, sieves, strainers, quarries, aggregate screening, etc.
