General information

Features and applications

DVB. rubber buffers have been designed to damp vibrations, shocks and noises produced by moving bodies or non-balanced vibrating masses of equipment and machines.

DVB elements are generally used as a bumper or as a limit stop for the absorption of vibrations.

Vibrations can cause:

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

damage to operator's 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 Shore A ±5 for the executions with AISI 304 stainless steel base.
