Frequently Asked Questions
Q: Is the GW 641-A compatible with 20mm bearing shafts?
A: No. The GW 641-A has a 25mm bearing ID and is not compatible with 20mm shaft applications. Use the GW 641-A-20MM variant if your lift truck requires a 20mm bore. Installing the wrong bearing ID will cause excessive side play and premature wear.
Q: What is the cross-reference part number for the GW 641-A?
A: The GW 641-A is equivalent to GW641 and conforms to the 95A Poly Load Wheel specification. Both part numbers identify the same wheel assembly with Durarun 95A polyurethane construction and 25mm bearing ID.
Q: Can the GW 641-A 4 inch wheel be interchanged with 5 inch wheels?
A: No. The 4.000 inch diameter wheel cannot be interchanged with larger wheels. Using incorrect diameter wheels will affect load distribution, truck height, and mast alignment. Always verify wheel diameter matches your lift truck specification.
Q: How long does a Durarun 95A polyurethane wheel typically last?
A: In typical warehouse conditions with regular use, the GW 641-A will last 12 to 24 months. Lifespan depends on floor type, load frequency, and maintenance. Inspect wheels quarterly for flat spots, cracks, or hardening. Replace if tread depth becomes uneven or the wheel loses grip.
Q: What symptoms indicate the GW 641-A wheel needs replacement?
A: Replace the wheel if you observe: flat spots or uneven wear patterns, visible cracks or chunks missing from the tread, reduced grip causing slipping during turns or under load, or audible grinding from the bearing. Any of these indicate failure is imminent.
Q: Is installation of the GW 641-A plug-and-play or does it require tools?
A: Installation requires removing the shaft clip, sliding off the worn wheel, and pressing the new GW 641-A wheel onto the 25mm bearing shaft. You will need a wheel puller and press or a bearing puller tool. Do not attempt to remove wheels with a hammer or pry bar as this damages the bearing. A shop press is recommended for safety and accuracy.
