Frequently Asked Questions
Q: What is the Shore A hardness rating of the GW 121 polyurethane tread?
A: The GW 121 features Shore A 95 hardness polyurethane tread, which is nominal industry standard for heavy-duty pallet jack wheels. This hardness provides excellent wear resistance, making the GW 121 ideal for rough concrete floors, outdoor use, and high-frequency loading cycles.
Q: How do the GW 121 dimensions compare to the GW 119 and GW 120?
A: The GW 121 measures 3.250 inch diameter x 3.660 inch width (82.55mm x 92.96mm metric), which differs from the GW 119 and GW 120 (both 3.000 x 3.750 inches). The GW 121 is larger in diameter but narrower in width. Do not interchange these part numbers; verify your jack model documentation for the correct size.
Q: What bearing specification does the GW 121 use?
A: The GW 121 is equipped with a 6204-2RS sealed deep groove ball bearing with a 20mm bearing ID. The RS designation means the bearing has rubber seals on both sides, providing protection against contamination and extending service life in warehouse and manufacturing environments.
Q: Should I upgrade from GW 119 or GW 120 wheels to the GW 121?
A: Upgrade to the GW 121 if your pallet jack model supports its larger 3.250 inch diameter and 3.660 inch width dimensions, and if you operate on rough or outdoor surfaces where higher hardness (Shore A 95) reduces tread wear. Do not force GW 121 wheels onto jacks designed for smaller wheels; incorrect fitment will cause steering and load-handling problems. Consult your jack manual to confirm compatibility.
Q: How long does the GW 121 wheel assembly typically last?
A: The GW 121, with its Shore A 95 hardness tread and sealed deep groove ball bearing, typically lasts 3 to 6 years in normal warehouse use and up to 5 to 7 years on smoother floors. Rough outdoor surfaces, heavy loading, and frequent use may shorten lifespan. Inspect quarterly for flat spots and bearing play. Replace both wheels as a pair to maintain balance and steering control.
