Where the bumper takes the hit
Contact face, body and mount
A bumper is a contact face, a body that sets the stop, and a mount that holds it to the machine.
-
What strikes it
A product, carriage, gate or moving arm meets the bumper at the end of its travel.
Send us
- What it is
- The direction it comes from
-
Contact face
Strike
The surface that takes the hit. Its size, edges and radius decide where the contact lands and how it meets the product.
We machine
- Face size and shape
- Edge breaks and radii
- Fasteners set below the face
Send us
- Face dimensions
- Whether anything slides on it
-
Body
Sets how far the moving part travels before it stops.
We machine
- Thickness or section
- Steps and chamfers
Send us
- Overall size
- The stopped position or gap
-
Mount
Holds the bumper to the frame or backing behind it.
We machine
- Holes, counterbores and slots
- Threads or inserts
Send us
- Hole pattern
- What it mounts to
Replacing a bumper?
Why bumpers are replaced
Common signs, and what each one changes on the machine. Your maintenance team makes the call.
-
Worn face
The contact face has worn down or grooved.
The stop position moves, or a fastener or the backing is exposed.
-
Cracked or chipped
Pieces break away after repeated strikes.
Loose fragments, and an uneven face that changes the contact.
-
Flattened
The bumper has lost height under repeated hits.
The moving part travels further before it stops.
-
Pulled-through holes
Holes stretched oval or fasteners pulling through.
The bumper shifts and no longer lines up with what it stops.
-
Marking the product
Scuffs or marks where the face meets the product.
Rejected or damaged product at the stop.
-
Softened or swollen
Heat, moisture or chemicals have changed its size or face.
The fit and the stop position change.
Send the old bumper with a photo of it in place. A worn bumper may have lost height, so tell us the stopped position if you know it.

Plastics for bumpers and stops
Common choices, and why
- UHMW Tough and abrasion-resistant, with a low-friction face. A common choice for wear and impact pads.
- HDPE Tough and economical for pads and blocks.
- Nylon Strong and wear-resistant. It takes on moisture, which we allow for when machining.
- Acetal Stiff and dimensionally stable, so it holds a precise stop position.
- Polyurethane A softer, more resilient face where the contact needs a little give.
Machined in Aurora
How your bumpers are made
±0.002"–
±0.005"
On critical dimensions, depending on the plastic. Specs and CAD files are kept, so a reorder matches the last batch.
-
Face and edges to your drawing
The contact face, edge breaks and radii machined so the strike lands where your drawing puts it.
-
Fasteners below the face
Counterbored holes keep screw heads clear of the strike, with threads or inserts where you need them.
-
Ready to mount
Inserts and hardware fitted before shipping, so there’s no second supplier.
