Use the machine reference for an existing replacement, or provide dimensions and duty data for a custom wheel. Printed dimensions are examples only and never replace fitment verification.
These sizes are request examples, not universal fitments. Bore, bearing, core and bolt layout must be confirmed.
| Example OD × width | Typical inquiry | Core bore / bearing | Bolt or drive interface |
|---|---|---|---|
| 250 × 80 mm | Reach-truck drive wheel | Buyer drawing / sample required | Confirm bolt circle, hole count and pilot |
| 254 × 102 mm | Electric-forklift drive wheel | Confirm bearing or machined hub | Confirm keyway, spline or bolt layout |
| 150 × 50 mm | Load / support wheel | Confirm bearing series and spacer width | Confirm axle and fork spacing |
Hardness is only one variable. Load, speed, heat build-up, floor, chemicals and duty cycle determine the final compound.
| Selection item | 93 Shore A nominal | 95 Shore A nominal | Quotation requirement |
|---|---|---|---|
| Ride and traction | More compliant; balanced cushioning and traction | Firmer; lower deformation and stable rolling | Confirm floor, speed and traction demand |
| Load rating (kg) | Calculated from dimensions, core, bearing, speed and duty cycle | Calculated from dimensions, core, bearing, speed and duty cycle | Provide maximum static and dynamic load |
| Tear / abrasion | Compound-specific; project testing can be agreed | Compound-specific; project testing can be agreed | Describe debris, joints, ramps and duty hours |
| Cold storage | Cold-service compound may be required | Cold-service compound may be required | Provide minimum temperature and cycle |
Final compound, hardness tolerance, load rating and inspection criteria are stated only in the approved quotation or drawing.
Send the drawing or sample with load, speed, floor and temperature data. Target prototype lead time is 5–7 working days after design, material and tooling confirmation; complex testing may take longer.
