General information

Features and applications

The rubber buffers have been designed to damp vibrations, shocks and noises produced by moving bodies or non-balanced vibrating masses of equipment and machines which can cause:

malfunctioning and reduction of the machine lifespan and/or of the adjacent ones;

damage to health;

noise.

Load diagrams for each single code are available on request.

See Technical data and guidelines for the choice.

Other executions

Special executions on request

Natural rubber NR, hardness 40, 70 tolerance ±5 Shore A for executions with AISI 304 stainless steel base.
