Frequently Asked Questions
Q: Why does the GW 335 include two different bearing sizes (20mm and 25mm)?
A: The GW 335 is engineered for applications requiring dual bearing support at different bore sizes. The 20mm bearing provides the primary load path while the 25mm bearing delivers additional support and stability. This dual-bearing design reduces wobble and extends bearing life under continuous operation. Verify your axle design accommodates both bearing sizes before ordering.
Q: Can I use only one bearing on the GW 335 if my axle does not support dual bearings?
A: No. The GW 335 wheel assembly requires both the 20mm and 25mm bearings installed for proper operation. Removing either bearing will cause misalignment, excessive play, and premature failure of the remaining bearing. If your axle supports only single bearings, order the GW 330 or GW 334 instead.
Q: Is the GW 335 compatible with standard manual pallet jacks or specialized equipment only?
A: The GW 335 is designed for manual pallet jacks and similar lifting equipment with dual-bearing axle designs. Check your equipment manual to confirm the axle accommodates both a 20mm and 25mm bearing bore. Not all standard pallet jacks support this configuration. Using the GW 335 on incompatible equipment risks bearing failure and steering malfunction.
Q: What is the load capacity and typical service life of a GW 335 wheel assembly?
A: The dual-bearing design of the GW 335 supports manual pallet jacks rated up to 5000-5500 lbs. The redundant bearing support extends service life to 24-30 months with regular maintenance. High-frequency use or loads exceeding rated capacity will reduce lifespan. Inspect bearings quarterly for play, noise, or grinding that signals replacement is needed.
Q: How do I properly install and service both bearings on the GW 335?
A: Install the 20mm bearing first on the axle, followed by the 7 inch nylon wheel, then install the 25mm bearing on the opposite side. Both bearings must seat fully against the wheel hub. Secure with cotter pins or axle nuts per your equipment specification. Monthly, spin both bearings independently to confirm smooth rotation. If either bearing exhibits roughness, replace that bearing immediately and re-inspect the wheel for damage.
