Frequently Asked Questions
Q: What are the exact dimensions of the SU S9150-XL load wheel?
A: The SU S9150-XL is 5.000 inches in outside diameter and 2.875 inches in width (also expressed as 127.00mm x 73.02mm). The inside diameter is 2.281 inches. These dimensions make it compatible with most standard electric lift truck and pallet truck axle assemblies that call for a 5 inch diameter wheel.
Q: What is Cushothane XL material and how does it perform compared to standard polyurethane?
A: Cushothane XL is a high-durability polyurethane compound formulated for superior cut, tear, and abrasion resistance. It is bonded to the steel core using XL3 proprietary bonding technology, which creates a stronger interface than standard adhesive methods. This results in a wheel that resists premature separation and holds up longer under continuous duty on rough warehouse floors.
Q: Are sealed ball bearings included with the SU S9150-XL?
A: Yes. The SU S9150-XL comes equipped with sealed precision ball bearings. Sealed bearings reduce maintenance requirements and protect against dirt and moisture ingress, which extends the service life of the wheel assembly in wet or dusty environments.
Q: What core material does the SU S9150-XL use and why is it important?
A: The SU S9150-XL features a precision-machined steel core made from high-strength alloy material. A steel core provides superior load-bearing capacity and resistance to deflection under heavy static and dynamic loads. This is critical for electric lift trucks and pallet trucks that must support concentrated loads without wheel collapse or drift.
Q: Can the SU S9150-XL be used as a direct replacement for OEM wheels on Crown or Toyota electric pallet jacks?
A: The SU S9150-XL can be used on Crown and Toyota models that specify a 5 inch diameter by 2.875 inch width wheel. Always verify the exact model number, serial range, and axle bore specifications before ordering. Dimension compatibility does not guarantee fitment if the axle bore diameter or depth differs from the wheel hub design.
Q: What is the typical service life of the SU S9150-XL wheel?
A: Service life depends on duty cycle, floor conditions, and load profile. On smooth warehouse concrete with moderate duty (8-12 hours per day), expect 2-4 years. On rough floors or in high-mileage operations (16+ hours per day), replace when the tread shows significant flat spots, chunking, or the wheel no longer tracks straight. Sealed bearings typically outlast the polyurethane tread.
