DVA.6 Rubber Buffers

Rubber and steel or stainless steel

Standard Executions

DVA.6

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.6-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 are designed to damp vibrations, shocks, and noises produced by moving bodies or non-balanced vibrating masses of equipment and machines. This helps prevent:

Malfunctioning and reduction of machine lifespan and/or adjacent components.
Damage to health.
Noise.

Load diagrams for each single code are available on request. Refer to Technical Data and Guidelines for Choice (page 728).

Special Executions on Request

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

Buffer Cross-Section Diagram

A cross-section diagram of a DVA.6 rubber buffer. It depicts a threaded stud (d) extending from a base plate, connected to a cylindrical rubber body. Key dimensions are labeled: D (outer diameter of the rubber body), L (length of the threaded stud), and d (diameter of the threaded stud). The hardness is specified in Shore A.

For DVA.6-SST models, the base plate is made of stainless steel.
