Frequently Asked Questions
Q: What are the cross-reference or equivalent part numbers for GWK-UL55-CK?
A: The GWK-UL55-CK is equivalent to GWK-L55-CK, replaces GWK-Eagle55-CK, and is cross-referenced as GWK-ELP55-CK. All four part numbers refer to the same complete wheel kit with identical specifications and fitment. Use any of these numbers when ordering as replacements.
Q: What is included in this complete wheel kit?
A: The GWK-UL55-CK includes precision-sealed bearing load wheels and steer wheels with 70D Shore hardness polyurethane, hardened steel axles, and all fasteners needed for installation. This is a full kit for replacing both front and rear wheels on Ultra UL5500 pallet jacks.
Q: Which pallet jack models is this kit compatible with?
A: The GWK-UL55-CK fits Ultra model UL5500 and compatible Eagle and Lift-Rite models of the same generation. The 70D polyurethane material and wheel diameter match factory OEM specifications. Always verify model compatibility before purchase.
Q: What wheel hardness and core material does this kit use?
A: The GWK-UL55-CK features polyurethane wheels with 70 Shore D hardness and a core of machined carbon steel. The 70D hardness provides excellent load capacity while maintaining good floor protection. The carbon steel core resists wear and maintains wheel concentricity.
Q: Are the bearings sealed, and what maintenance is required?
A: The GWK-UL55-CK wheels come with precision-sealed ball bearings that require no periodic lubrication. The seals protect against dirt, moisture, and contaminants. During routine maintenance, inspect the bearings for play or noise; if grinding occurs, replace the wheel assembly.
Q: How long do these wheels typically last in service?
A: With proper maintenance and normal warehouse use, the GWK-UL55-CK wheels provide 2-3 years of service. Heavy use or rough floors may accelerate wear. Inspect wheels every 6 months for cracking, flat-spotting, or bearing wear. Replace immediately if wheels show uneven wear or rolling resistance increases.
