Frequently Asked Questions
Q: What makes GWK-D40-LW-XL different from standard GWK-D40-LW wheels?
A: GWK-D40-LW-XL features extra-large wheels with 97A durometer polyurethane construction. These wheels provide enhanced stability, smoother movement, and superior load distribution compared to standard wheels. The larger diameter and higher durometer rating (97A is harder than typical 70D or 92A) result in longer lifespan and reduced floor marking. Both models fit Big Joe D40 jacks, but XL is optimized for warehouses, display floors, and carpeted surfaces.
Q: Can I upgrade from standard D40 wheels to GWK-D40-LW-XL wheels?
A: Yes. GWK-D40-LW-XL wheels are compatible with Big Joe D40 models and can replace any existing D40 wheel set. The larger wheel diameter may slightly alter the jack geometry and steering radius, but this is not problematic. However, do not upgrade to XL wheels if your facility has restricted clearance under racks or doorways. Measure your available space before ordering.
Q: Is the 97A durometer rating suitable for all warehouse floor types?
A: 97A durometer wheels are non-marking and suitable for polished floors, display areas, and retail environments. They perform well on smooth concrete but may track (stick) slightly on very tacky or sticky floors. For rough outdoor surfaces or unprepared concrete, 70D wheels are more forgiving. 97A is recommended for climate-controlled warehouses and showrooms where floor quality is high.
Q: What is the steel core material specification for GWK-D40-LW-XL?
A: GWK-D40-LW-XL wheels use steel alloy cores per OEM specification, engineered to support the full D40 load rating without deflection or core cracking. The steel provides rigidity needed for extra-large wheels and maintains dimensional stability across temperature ranges. Do not substitute aluminum or plastic cores, as these will fail under load and create safety hazards.
Q: How much longer do GWK-D40-LW-XL wheels last compared to standard wheels?
A: 97A durometer wheels typically last 4-5 years under normal warehouse conditions, compared to 2-3 years for standard 92A wheels. The harder polyurethane resists abrasion and deformation better. However, lifespan increases only if the jack is maintained properly and not overloaded. Poor bearing lubrication or excessive load will negate the durability advantage.
Q: Do GWK-D40-LW-XL wheels require special tools or training to install?
A: No special tools are required beyond a socket set and adjustable wrench. Installation is identical to standard wheels: lift the jack, remove fasteners, slide out old wheels, insert new assemblies ensuring bearings seat properly, reinstall fasteners, and test for free rotation. The larger wheel size does not complicate the process. Installation takes approximately 60 minutes due to extra wheel weight (handling care, not complexity).
