Silent Block / Shock-absorbers

Silent Block


Good mechanical properties. Excellent resistance to oils and greases in general, various fluids, etc. High resistance to ozone. In recent years, Oldrati has developed special mixes that can be used at very high and low temperatures (range 50°C to +130°C).

Operating temperature range:
Depends on the material used and Oldrati's dedicated formulation.


Dimensions Standard Oldrati standard (catalogue of dimensions available). To customer drawing

Note: Oldrati makes all gaskets to customer drawing. Sizes range from a few millimetres up to 2500 mm.
