Frequently Asked Questions
Q: What are the specifications of the GW 666 load wheel?
A: The GW 666 is a 6.000 inch diameter x 4.000 inch width load wheel molded from Durarun 95A polyurethane. The bearing ID is 35.000 inches. The 95A Shore hardness provides excellent durability with non-marking tread characteristics. Metric equivalent is 152.40mm x 101.60mm. This wheel is optimized for electric lift truck applications requiring larger diameter for ground clearance or load distribution.
Q: How does the GW 666 wheel compare in size to smaller wheels like the GW 654 series?
A: The GW 666 is significantly larger. It measures 6.000 inches in diameter versus 5.000 inches for the GW 654 series, and 4.000 inches wide versus 3.62 to 3.63 inches. The larger diameter provides greater ground clearance and distributes loads over a larger contact patch. However, the bearing ID remains 35.000 inches on both. Do not substitute 654 and 666 wheels unless equipment is specifically designed for mixed wheel sizes.
Q: Can I use the GW 666 as a replacement for a GW 654 wheel on my lift truck?
A: No. Direct substitution is not recommended without equipment verification. The larger diameter changes the lift truck geometry, turning radius, and load balance. A 6-inch wheel requires different brake settings and may affect operator visibility and handling. Always consult your equipment manual or contact the original manufacturer before upgrading wheel sizes. An incorrect size may void the equipment warranty.
Q: Does the GW 666 have a non-marking tread and what does that mean?
A: Yes. The GW 666 features a non-marking tread formulation in the Durarun 95A polyurethane. Non-marking means the wheel does not leave black residue or scuff marks on polished concrete, tile, or other finished floors. This is critical for retail, food service, and healthcare facilities where floor appearance matters. The 95A durometer combined with non-marking additives may reduce tread life slightly versus standard marking compounds.
Q: What maintenance is required for the GW 666 wheel?
A: Inspect the wheel monthly for cracking, flat spots, or separation between the polyurethane and steel core. Check bearing condition by rotating the wheel by hand and listening for roughness. Clean debris from the tread to maintain traction. Do not expose the wheel to direct sunlight or extreme heat for extended periods, as Durarun polyurethane degrades over time in UV light. Replace the wheel when tread depth becomes uneven or the tire loses roundness. A worn wheel increases equipment instability and braking distance.
