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.

Special executions on request

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