Standard executions

  • DVA.4: threaded stud and base plate in polished zinc-plated steel, vibration-damper body in natural rubber NR, black colour, hardness 40, 55, 70 Shore A ±5.
  • DVA.4-SST: threaded stud and base plate in INOX AISI 304 stainless steel, vibration-damper body in natural rubber NR, black colour, hardness 55 Shore A ±5.

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.

Special executions on request

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