silicone rubber pad for shock absorber

A silicone rubber pad provides a compliant face at the point where a component meets its intended support or stop. Selecting the contact area helps place the rubber where it can perform that role. Thickness then needs to be considered with the available travel and the space between adjoining parts.

The backing surface should support the pad rather than leave a thin overhang to receive the load. If the moving part approaches at an angle, assess where it first touches the rubber and how contact develops. The formulation and geometry require evaluation for the actual duty; a pad alone does not establish the characteristics of a complete shock absorber.

Keep the receiving area clean during fitting and use the retention arrangement intended for the design. After operation, inspect the working face for a localized mark that falls outside the planned contact area. Correct the alignment or support as needed before replacement so the pad continues to meet the component through its intended surface rather than a vulnerable corner.

Material options

Custom silicone or rubber formulation, with dimensions and color adapted to the mating component.

Hardness range

Silicone: 20–80 Shore A; rubber: 30–90 Shore A. Assess the grade against this fit requirement: The backing surface should support the pad rather than leave a thin overhang to receive the load.
