Custom made shock absorber HNBR rubber washer

A custom HNBR rubber washer can form a flexible contact layer in a cushioning or shock-absorber arrangement. The mating faces should direct contact through the intended rubber area rather than allowing an adjacent rigid feature to strike first.

ETOL offers dimensional, material, hardness and color options. Define the center location, outer footprint and assembled thickness around the actual hardware. If the contact is concentrated near an edge, the washer may deform locally instead of responding across its intended surface.

Check the assembly through the movement that brings the parts together. Observe whether the washer stays centered and whether another feature bypasses it. Evaluate the required cushioning behavior at the intended operating conditions. During maintenance, inspect for localized cuts, permanent compression or a displaced outer edge. Correct misalignment or a sharp contacting surface before replacing the rubber. Keep the washer free of debris during reassembly so a small hard particle does not create a new concentrated contact point beneath a component that otherwise appears correctly seated.
