Product Overview

A custom rubber shoulder washer combines an annular face with a projecting section that locates within an opening. The shoulder and face need separate dimensions for the receiving hardware. For shock related use, the complete assembly determines where the rubber is supported and how it can deform.

Check that the shoulder reaches its intended position without bottoming out before the face is supported. Its bore should match the passing hardware, while the surrounding rubber should not be cut by a sharp opening edge. The fastening method should establish the designed compression instead of crushing the washer to make an unsuitable stack feel tight. Select material and hardness for the actual load, motion, and environment. Assess the completed arrangement for uneven deformation or unintended metal contact. During replacement, preserve the shoulder length and face thickness together; matching only the outside diameter can change the locating relationship and available movement. Inspect the receiving parts if the old washer shows a strongly uneven contact pattern.

Material options: Rubber. Custom formulation and color for the intended contact conditions.
Hardness selection: Rubber: 30–90 Shore A. The fastening method should establish the designed compression instead of crushing the washer to make an unsuitable stack feel tight.
Custom dimensions: A custom rubber shoulder washer combines an annular face with a projecting section that locates within an opening.
Fit & assembly: Check that the shoulder reaches its intended position without bottoming out before the face is supported.
Use & inspection: During replacement, preserve the shoulder length and face thickness together; matching only the outside diameter can change the locating relationship and available movement.

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.
