Anti vibration rubber mount rubber damper bumper

A rubber damper bumper gives a moving component a resilient contact point at a defined part of its travel. The custom shape should match both the mounting seat and the face that meets it. Where the part also serves as a support mount, the steady load needs to be considered alongside the stopping contact.

Observe the approach direction before fixing the bumper location. A glancing impact may roll across the edge, while a centered approach uses the intended contact face. The structure behind the rubber must support the force without allowing the whole bumper to shift.

Leave room for the working deformation and check that another rigid surface does not become the stop first. Compound and hardness choices depend on the actual contact conditions, with no damping value implied by appearance. After initial use, examine the contact marks on the bumper and the mating part. A mark concentrated at one corner can reveal misalignment that should be corrected before replacing a worn buffer with an identical one.

Material options

Custom rubber compound and color, selected for the contact conditions and required geometry.

Hardness range

30–90 Shore A for rubber. Assess the grade against this fit requirement: Leave room for the working deformation and check that another rigid surface does not become the stop first.

Custom profile & fit

The custom shape should match both the mounting seat and the face that meets it.

Assembly considerations

Observe the approach direction before fixing the bumper location.
