Frequently Asked Questions
Q: What are the exact dimensions and bearing specifications of the GW 548-A?
A: The GW 548-A load wheel assembly is 4.000 inches in diameter and 2.000 inches in width (101.60mm x 50.80mm). The bearing bore ID is 0.75 inches (19.05mm). It has a cast iron machined core with 92A durometer polyurethane tread.
Q: What electric pallet jack models does the GW 548-A fit?
A: The GW 548-A is engineered for Crown GPW series electric pallet trucks and other electric material handling equipment using 4 x 2 wheel assemblies with 0.75-inch (19.05mm) bearing shafts. Verify your jack OEM documentation before purchase.
Q: How does the GW 548-A bearing bore size compare to other load wheel options?
A: The GW 548-A uses a 0.75-inch (19.05mm) bearing bore, which is common for mid-range electric jacks. Some premium models use 25mm bores, while older units may use 22mm. Mixing bore sizes will cause the wheel to bind on the shaft or have excessive side play.
Q: Is the GW 548-A a bolt-on replacement or does it require pressing?
A: The GW 548-A requires bearing press installation. The wheel hub must be pressed onto the shaft using a proper wheel press or bearing puller. Do not attempt to hammer the wheel onto the shaft, as this will damage the bearing seals and cause premature failure.
Q: What is the rated load capacity of the GW 548-A wheel assembly?
A: The GW 548-A specifications provided do not include a rated load capacity. Load capacity depends on the bearing rating and the number of wheels on your jack. Consult your jack manual for the approved load limit.
Q: Can I use GW 548-A wheels as a complete replacement set if my jack has four load wheels?
A: Yes, if all four wheels match the original equipment (same 4 x 2 dimensions and 0.75-inch bearing bore). Replace all wheels at the same time to ensure even load distribution. Mixing wheel sizes will cause the jack to pull to one side.
