Frequently Asked Questions
Q: What is the W48 variant and is GWK-MJ55-W48-CK the correct replacement for my jack?
A: The W48 is an extended-fork variant of the Maxx Jack MJ55 line, denoting a wider or alternative fork configuration (likely extra-wide fork geometry). GWK-MJ55-W48-CK is the complete load wheel kit engineered for this specific model. Check your jack nameplate for MJ55-W48 designation before ordering. Using the wrong variant kit on your jack will result in improper wheel fit and bearing misalignment.
Q: What does GWK-MJ55-W48-CK include?
A: GWK-MJ55-W48-CK includes ultra-polyurethane load wheel assemblies (Shore D70 hardness), sealed bearing assemblies, carbon steel axles, roll pins, and fasteners. It is a complete wheel kit replacement. The kit does not include steer wheels; if steer wheels are also worn, order them separately or request a full wheel kit option from your supplier.
Q: Is GWK-MJ55-W48-CK suitable for continuous material-handling duty?
A: Yes. GWK-MJ55-W48-CK is rated for direct replacement and maintenance of Maxx Jack MJ55-W48 and equivalent models in standard warehouse and manufacturing material-handling applications. The carbon steel axles, sealed bearing assemblies, and ultra-polyurethane wheels are engineered for 8-hour shift duty with normal pallet loads. Heavy-duty or extreme-temperature environments may reduce wheel life.
Q: Are there any cross-reference or equivalent part numbers for GWK-MJ55-W48-CK?
A: According to available documentation, no cross-reference or superseding part numbers have been identified for GWK-MJ55-W48-CK. This is a proprietary Maxx Jack part. If you have an older MJ55-W48 jack or need compatibility verification, contact Maxx Jack directly with your jack serial number. Do not assume older jacks are compatible without confirmation.
Q: What is the expected service life and maintenance schedule for GWK-MJ55-W48-CK?
A: Under standard warehouse duty, load wheels typically last 18 to 36 months before visible wear requires replacement. Inspect wheels every 6 months for flat spots, bearing play, or polyurethane degradation. Carbon steel axles can rust if exposed to moisture; apply light machine oil during seasonal maintenance. Replacing wheels before bearing damage occurs will extend your pallet jack service life by 5 to 10 years.
