Polyurethane Flat-Tread Wheels with Protruding Hubs
Yellow polyurethane contact wheels with metal hubs for encoder measuring, machine contact and material-feeding arrangements. Each selectable configuration identifies either nominal outside diameter or rolling circumference, plus tread face width and the available finished-bore range. These dimensions are not interchangeable.

Exact Bore Required
A bore range is a configuration range, not an adjustable shaft hole. Specify one exact finished bore in the order requirements and confirm the shaft interface before ordering. Hub outside diameter and overall length can vary with the bore and wheel configuration. Face width is the polyurethane contact width, not necessarily total hub length. Do not infer a keyway, bearing, included screw size or shaft tolerance from a family photograph.
Construction and Model Selection
The original product views show flat polyurethane treads, metal centers, protruding hubs, shaft bores and retaining-screw openings. Solid and spoked center forms appear in the series. Exact hardness, alloy, tolerance, speed, load and temperature limits are not established for every selectable configuration; confirm any required limits for the actual model. Do not use the dimensions of one configuration as another model's mounting drawing.
Measuring and Installation
- Match the selected diameter or circumference and face width to the machine and contact material.
- For encoder use, calibrate effective rolling distance on the actual material. Check contact force and slipping; nominal circumference is not a certified measurement accuracy.
- Check the finished bore, retaining method, hub projection and neighboring-component clearance before installation.
- Isolate power before installing the wheel. Secure the connection and check alignment and free rotation before production.
- Inspect the tread and hub for wear, damage or looseness. Replace damaged components before further use.
Original Product Photographs
The following original series photographs show the available tread and hub construction styles. They are not exact-size photographs of every offered bore combination or evidence of a multi-wheel pack. An encoder, shaft and mounting bracket are separate components and are not included. Refer to the selected configuration and confirm the mounting interface before ordering. Inch equivalents are rounded to three decimal places.
