High quality silicone rubber vibration damper/NBR rubber buffer

A custom NBR rubber buffer provides a flexible contact element for a defined damping arrangement. Silicone is another material choice within this product category. These compounds should be treated as separate configurations, with the selected version matched to the actual environment and required deformation.

When comparing versions, use the same mating parts and installed conditions. The rubber's free shape, seating behavior, and loaded position all contribute to the final fit. A replacement that has the same outside dimensions can still affect the working gap if its material behaves differently. The surrounding component should remain correctly located without hard contact outside the intended buffer face.

Choose the compound around substances and temperatures present at the interface, including maintenance exposure. During inspection, look for changes in shape, seating, or contact pattern. Keep the selected material and geometry consistent when replacing the part unless the revised configuration has been evaluated for the assembly. A different color or a softer feel is not enough information to establish equivalent operation.
