Silicone rubber shock absorber mount rubber buffer/damper

A rubber shock absorber or buffer provides an elastomer contact within a mechanical assembly. The custom molded shape should match the mounting position and the direction of the expected contact. Its behavior depends on the rubber construction, the supported area, and the movement of the adjoining parts.

Define where contact occurs and how much space remains as the buffer is compressed. The moving mass, speed, load direction, and frequency of contact influence the selection. A part that fits the available mounting hole may still be unsuitable if it receives force on an unsupported edge or is compressed beyond the intended range.

Install the buffer on a suitable support and check the complete mechanism throughout its motion. Keep nearby parts from contacting a hard stop before the rubber reaches its intended working position. Any required shock or vibration performance must be established for the complete system rather than assumed from silicone hardness alone. During maintenance, inspect for tears, loosening, or permanent deformation. Correct misalignment or concentrated contact before fitting a replacement so the new part is loaded as designed.

Material options

Custom silicone compound; formulation and geometry developed together.

Hardness selection

Silicone options: 20–80 Shore A. A part that fits the available mounting hole may still be unsuitable if it receives force on an unsupported edge or is compressed beyond the intended range.

Custom geometry

The custom molded shape should match the mounting position and the direction of the expected contact.

Fit evaluation

Install the buffer on a suitable support and check the complete mechanism throughout its motion.
