Frequently Asked Questions
Q: What is the 0000-WL-12003 load wheel designed for?
A: The 0000-WL-12003 is a heavy-duty polyurethane load wheel assembly designed for manual and powered pallet jack applications requiring robust tread and precise bearing fit. The 6204 bearing and diameter specification fit multiple pallet jack models from Crown, Toyota, Raymond, Yale, Hyster, and similar manufacturers used in distribution and warehouse environments.
Q: What are the exact specifications of the 0000-WL-12003?
A: Core: Machined steel hub with polyurethane tread bonded to the surface. This configuration provides load capacity and durability required for pallet handling and material transport applications.
Q: How does the 0000-WL-12003 compare to smaller diameter wheels like the WL 12002?
A: The 0000-WL-12003 uses a larger bearing (6204 vs. 6003Z). The heavier-duty construction suits pallet jacks carrying higher loads. Do not substitute smaller diameter wheels on equipment designed for 0000-WL-12003 specification, as undersized wheels cause bearing failure and instability.
Q: Does the 0000-WL-12003 work in cold storage environments?
A: Standard polyurethane tread becomes stiff and loses grip in temperatures below freezing. For cold storage pallet jack applications, verify that the standard polyurethane compound meets your temperature requirements. Contact us if your equipment operates in subfreezing conditions, as cold-rated compounds may be available.
Q: What is the typical replacement interval for the 0000-WL-12003?
A: Load wheel life depends on load frequency, weight, floor surface, and floor conditions. Heavy use in distribution environments typically requires replacement every 2-4 years. Inspect regularly for tread wear, cracking, and flat spots. Replace when these conditions appear or when bearing play becomes excessive.
Q: Can the 0000-WL-12003 bearing be serviced or must the entire wheel assembly be replaced?
A: The 0000-WL-12003 is supplied as a complete bearing-to-tread assembly. If the bearing fails, the entire assembly must be replaced. The machined steel core and bonded polyurethane tread cannot be separated for bearing-only replacement, making full assembly replacement the practical and reliable solution.
