Product Overview

A rubber protective bushing can provide a custom flexible layer between mating components. EPDM and silicone are material options, selected for the specific exposure and intended role. The outside seat, center passage, and length should be defined from the assembly rather than from the general bushing name.

Check the surfaces that contact the rubber and the movement expected between them. The bushing needs support without being forced into a position that distorts one interface to fit another. Nearby shoulders and fasteners should leave the required axial room.

Choose the formulation for the temperature and substances present. Install squarely and inspect both ends after the center component is positioned. Follow the intended fastening arrangement to keep the rubber in its designed state. During maintenance, look for cuts, rubbing, or permanent shape changes on both mating surfaces. Replace with the matching compound and profile, particularly where visually identical EPDM and silicone versions are used in different parts of an assembly.

Material options: EPDM / Silicone. Custom formulation and color for the intended contact conditions.
Hardness selection: Rubber: 30–90 Shore A. Silicone: 20–80 Shore A. A rubber protective bushing can provide a custom flexible layer between mating components.
Custom dimensions: The outside seat, center passage, and length should be defined from the assembly rather than from the general bushing name.
Fit & assembly: The bushing needs support without being forced into a position that distorts one interface to fit another.
Use & inspection: Replace with the matching compound and profile, particularly where visually identical EPDM and silicone versions are used in different parts of an assembly.

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.
