Product Overview

Custom silicone mounts can be developed for a rubber damping arrangement where the mounting outline and installed space are defined by the equipment. Buna-N and silicone are different material choices within this product category. Selecting between them requires attention to the actual environment; matching the dimensions does not make two compounds interchangeable.

The mounting geometry determines where the rubber is held and where it can deform. A broad contact face, a narrow locating section, and a recessed seat each play a different role in the assembly. Review those features together so that tightening or seating the part does not concentrate the load in an unintended area. The supported component should remain correctly located while the rubber performs its intended compliant function.

When comparing material versions, use the same assembled conditions to assess fit and movement. Changes in compound can affect the feel of installation and the way the mount settles under load. Keep the selected version consistent during maintenance, and inspect surrounding parts for contact marks if the equipment begins behaving differently after a replacement.

Material options: Custom silicone compound; formulation and geometry developed together.
Hardness selection: Silicone options: 20–80 Shore A. The mounting geometry determines where the rubber is held and where it can deform.
Custom geometry: Buna-N and silicone are different material choices within this product category.
Fit evaluation: A broad contact face, a narrow locating section, and a recessed seat each play a different role in the assembly.
Color & OEM: Custom colors; part identification clear of mounting seats and loaded faces.

Ordering this custom component

Can the shape be adjusted to my mating parts?

Yes. Show the receiving opening, contact surfaces and clearance limits. We can review the dimensions and retaining features around the intended fit.

Which details should be agreed before tooling?

Agree the critical dimensions, material, hardness, visible surfaces and sample requirements. Explain how the part is installed and which interfaces control its function.

Can a sample help define the replacement?

A sample can help explain the structure. Compare it with the assembly because wear, swelling or compression may have changed its original dimensions.

How is the quotation for this part determined?

The material, part geometry, tooling, quantity and finishing affect the quotation. Include the intended batch size and delivery destination when describing your requirements.
