Q: What is the SU S663 load wheel and what is it used for?
A: The SU S663 is a replacement load wheel for electric lift truck applications. It is engineered to support the rear or mid-wheel positions and handle the load safely during material handling and transportation tasks. This is an aftermarket wheel suitable as a direct replacement for OEM components.

Q: Which electric lift truck models are compatible with the SU S663?
A: The SU S663 is compatible with electric lift trucks from Crown, Toyota, Raymond, Yale, Hyster, and other major manufacturers.

Q: What material is the SU S663 load wheel made from?
A: The SU S663 features a polyurethane tread bonded to a steel or cast-iron wheel core. Polyurethane provides non-marking performance, durability on smooth concrete floors, and good grip in dry to moderately wet conditions. The core material ensures strength and rigidity under load.

Q: How do I install the SU S663 load wheel on my electric lift truck?
A: Lift and safely support the truck on blocks. Remove fasteners or press-fit hardware securing the old wheel to the axle. Slide or press the SU S663 onto the axle, ensuring it seats fully. Reinstall fasteners or hardware and verify the wheel rotates freely without binding or contact with the frame.

Q: How long does the SU S663 load wheel typically last?
A: The SU S663 lifespan depends on load weight, floor condition, and operating speed. In standard warehouse environments with moderate loads on smooth floors, the SU S663 typically provides 1 to 2 years of service. Heavy loads, rough floors, or continuous high-speed operation reduce lifespan. Inspect regularly for tread wear and bearing condition.
