Frequently Asked Questions
Q: What type of bearing assembly is the SYM5003?
A: The SYM5003 is a sealed roller bearing assembly designed for load wheel and steering wheel applications on manual pallet jacks. It features a steel race, ball or roller elements, and a sealed cartridge to minimize dirt ingress and extend service life.
Q: Which manual pallet jack models use the SYM5003 bearing assembly?
A: The SYM5003 is compatible with standard manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and CAT. It fits most load wheel and steering wheel hubs with standard 17 to 25 millimeter bore diameters. Verify hub bore size and axle length match before ordering.
Q: What is the rated load capacity for the SYM5003 bearing assembly?
A: The SYM5003 is rated for loads up to 5500 pounds per pair when installed as load wheel bearings on a 5500-pound capacity pallet jack. Capacity depends on bearing size, seal type, and installation configuration. Do not exceed the manual pallet jack rated load limit.
Q: How long does the SYM5003 bearing assembly typically last?
A: The SYM5003 typically provides 3 to 7 years of service in warehouse environments, depending on operating hours, surface conditions, and maintenance. Sealed bearings last longer than open types. Replace if rotation becomes rough or noisy.
Q: What maintenance is required for the SYM5003 bearing assembly?
A: The SYM5003 is sealed and requires no lubrication or regular maintenance. Inspect quarterly for damage, excessive play, or corrosion. Clean debris from the wheel hub and axle. Replace the bearing if it shows signs of wear, discoloration, or grinding noise.
Q: Are equivalent bearing assemblies available for the SYM5003?
A: The SYM5003 is manufactured to OEM specifications. Equivalent manual pallet jack load wheel bearings may be available under different part numbers from other suppliers, but verify bore size, outer diameter, and seal type match your pallet jack wheels before substituting.
