Frequently Asked Questions
Q: Is GW 621 the same as GW 621-A or GW 621-A-DS?
A: GW 621, GW 621-A, and GW 621-A-DS have identical wheel dimensions (3.250 inch diameter by 4.200 inch width) and 95A hardness polyurethane tread. The differences are in bearing sealing and internal components. GW 621 has standard open or single-sealed bearings. GW 621-A uses improved seal design. GW 621-A-DS adds double sealed bearings for dusty or wet environments. All three are mechanically interchangeable on the same hub.
Q: What electric lift truck models use the GW 621 load wheel?
A: GW 621 is designed for generic electric lift trucks and pallet jacks that accept GW 621-series load wheel assemblies. To verify fit, check your trucks service manual or parts list for the original equipment manufacturer (OEM) part number. Cross-reference that number to GW 621. If unsure, measure the hub bore diameter (should be 25mm or 0.984 inch) and compare wheel placement geometry on your truck.
Q: Does GW 621 have non-marking properties?
A: Yes. GW 621 features a non-marking red polyurethane tread. This tread will not scuff or mark polished concrete, epoxy floors, or linoleum common in food processing and pharmaceutical warehouses. If your facility has strict floor protection requirements, GW 621 is safe to deploy.
Q: How do I know when a GW 621 load wheel needs replacement?
A: Replace GW 621 when tread depth drops below 0.5 inch, when the tread shows flat spots or uneven wear, when you hear grinding or feel grinding vibration during movement, or when the wheel no longer rolls freely (bearing failure sign). Worn wheels reduce truck maneuverability and increase motor load.
Q: What is the load capacity for one GW 621 wheel?
A: Load capacity per wheel is not a standalone specification. Instead, the truck frame and axle assembly determine total load rating. A standard electric pallet jack with four GW 621 wheels typically handles 4,000 to 6,000 pounds total load. Always refer to your truck nameplate for maximum capacity. Exceeding rated capacity causes bearing failure and frame damage.
