A solid PU contact layer around the fixing
These pale-yellow polyurethane washers place a solid polymer layer around a fastener or locating pin. The centre hole provides clearance; the annular face separates the adjoining components. Use the thickness to set a local gap and the outside diameter to fit the bearing surface.
The 11 stock items are fixed ID, OD and thickness combinations. Choose a size against the complete mating geometry. The washer is a solid polyurethane part, so its installation differs from a soft foam cushion or a metal locking washer.

WHERE IT FITS
Where a polymer face meets moving or clamped hardware
Guide and stop interfaces
Use the ring at a defined guide or stop location, with the contact load and relative movement included in the part specification.
Local assembly spacing
Select a listed thickness to establish separation around a bolt or pin without covering its central passage.
BEFORE YOU FIT THE PART
Selection & installation
Start with the contact geometry, then check the part in the assembled condition.
Adhesive-backed assembly options →Start with the pin clearance
The listed ID is the actual hole dimension. Compare it with the shaft, bolt and assembly clearance.
Check the bearing footprint
Keep the annular face supported by the mating component. An oversized OD can leave an unsupported edge.
Specify load and contact motion
State the clamped load or movement at the interface when ordering PU washers for a wearing contact position.
Fit the selected construction
Retain the washer between the designed mating faces. Align the centre hole before clamping and keep the bearing face fully supported.

Ordering & product questions
Are these polyurethane foam washers?
They are solid polyurethane rings. They have a flat annular section rather than a cellular foam body.
Can I mix any listed ID with any OD?
Each SKU identifies one complete size. Select one of the 11 listed combinations.
Does the yellow shade identify a hardness?
Colour describes appearance. Specify the required PU grade and hardness in the order when those are acceptance criteria.
