Frequently Asked Questions
Q: What is included in the SU 348-A load wheel assembly and how does it differ from SU 348?
A: SU 348-A is a complete load wheel assembly that includes the wheel, hub, and bore components ready to install as a single unit. SU 348 is the wheel portion only. Order SU 348-A for a complete plug-and-play replacement assembly. Order SU 348 only if you have existing compatible hub components and need only the wheel portion.
Q: What are the complete specifications of the SU 348-A assembly?
A: SU 348-A specifications are: wheel outer diameter 3.25 inches (82.55mm), wheel width 5.75 inches (146.05mm), inside diameter 1.938 inches, bore outside diameter 2.0467 inches, bore depth 1.447 inches, hub width 5.75 inches, and material Cushothane XL. These dimensions must match your jacks existing wheel bore specifications before installation to prevent fitment problems.
Q: Which pallet jack makes and models is SU 348-A compatible with?
A: SU 348-A compatibility depends on your jacks bore configuration and width specifications. It may fit Crown, Toyota, Raymond, Yale, Hyster, Linde, or other OEM brands with matching bore dimensions. Provide Superior with your jacks make, model, serial range, and current wheel configuration for accurate compatibility verification. Do not install without confirming fitment, as incorrect installation damages the axle and voids warranties.
Q: What tools are required to replace all four wheels with SU 348-A assemblies?
A: Replacement requires an appropriately sized wrench or socket set, a pallet jack lift stand or blocks for safe lifting, and basic hand tools. Lift the jack safely so all wheels clear the ground. Remove fasteners or axle pins, slide the old assemblies off the axle, and install new SU 348-A assemblies by reversing the process. Torque all fasteners per your jacks manual. Replace all four wheels during the same maintenance interval to ensure consistent performance and safety.
Q: What is the load rating and maximum operating capacity for SU 348-A?
A: SU 348-A load capacity is determined by your jacks frame rating, not the wheel assembly itself. Typical pallet jacks have capacities of 2000 to 5500 pounds total. Do not exceed your jacks nameplate maximum load as overloading causes wheel flattening, bearing failure, and safety hazards. Distribute loads evenly across all four wheels. Uneven loading accelerates wear and reduces component lifespan.
Q: How long do SU 348-A assemblies last and what maintenance prevents premature failure?
A: Under normal warehouse conditions, SU 348-A assemblies typically last 18 to 36 months before wheel replacement is necessary. Maintain them by inspecting monthly for cracks, flat spots, or uneven wear. Keep wheel bores and treads clean and free of debris. Ensure fasteners remain tight and wheels spin freely without binding. Rotate wheels to equalize wear if possible. Replace all four wheels at the same time when wear becomes visible to maintain consistent jack performance and safety.
