Frequently Asked Questions
Q: Does the GWK-2W7-LW work with Unicarriers model 2W7 only or are there compatible variants?
A: The GWK-2W7-LW is designed for Unicarriers model 2W7 manual high-lift pallet jacks. An extended-load variant, GWK-2W7-LW-XL, is available for applications requiring higher durometer rating. Do not substitute one variant for the other. Verify your exact model number and application (standard duty vs. heavy duty) before ordering. Using the wrong wheel kit will result in improper load distribution and potential equipment failure.
Q: What is Durarun 95A polyurethane and how does it differ from Ultra-Poly 70D?
A: Durarun 95A is 25 points harder than Ultra-Poly 70D on the Shore A scale, making it more wear-resistant for heavy-duty warehouse and industrial floors. 95A wheels last longer in abrasive environments (asphalt, unsealed concrete, outdoor loading docks) than 70D wheels. The trade-off is reduced shock absorption and greater floor marking potential on polished surfaces. Durarun 95A is the standard for manufacturing and logistics operations with 200+ picks daily.
Q: Can I use Durarun 95A wheels on display floors or polished concrete without marking?
A: No. Durarun 95A wheels are not rated non-marking and will leave residue on polished concrete, sealed wood, and waxed tile. Use these wheels exclusively in warehouses, manufacturing areas, and rough industrial environments. If your operation includes both display areas and warehouse zones, maintain separate jacks with appropriate wheel types for each area, or accept marking issues on display floors.
Q: What is included in the GWK-2W7-LW kit and what tools do I need for installation?
A: The kit includes two complete Durarun 95A load wheel assemblies with axles, sealed bearings, and all fasteners. You will need a 15mm socket wrench or adjustable wrench and a 3/16 inch hex wrench (for set screws if present). Installation time is approximately 25 minutes. Do not use pneumatic or power tools. Torque axle nuts to 30-35 foot-pounds. After installation, manually spin each wheel to verify smooth, quiet rotation.
Q: What load capacity does the GWK-2W7-LW maintain and are there weight restrictions?
A: The Unicarriers 2W7 standard load rating is 5500 pounds, which the GWK-2W7-LW wheels support when properly installed with bearing preload and axle nut torque within specifications. Do not exceed this limit. The extended-load variant GWK-2W7-LW-XL supports 6000 pound operations but requires reinforced axles (included in that kit). Using standard wheels for extended-load applications will damage bearings and cause premature failure.
Q: How often should I inspect or replace the Durarun 95A wheels and what is typical lifespan?
A: Inspect wheels every 45 days in high-cycle operations. Replace when visible wear exceeds 3/16 inch depth or wheels cannot roll freely due to bearing damage. In typical warehouse use (4-6 hours daily on concrete), expect 24-36 months of service. Heavy continuous use or outdoor operation reduces lifespan to 12-18 months. If wheels are flat-spotted, cracked, or generating grinding noise, replace the entire kit immediately. Operating on damaged wheels risks jack instability and operator injury.
