Frequently Asked Questions
Q: What are the cross-reference part numbers for GW 224?
A: GW 224 is equivalent to GP224 and GP 224. All three part numbers represent the same industrial load wheel axle. Use any of these part numbers when ordering a replacement; they are fully interchangeable.
Q: What material and hardness specification does GW 224 meet?
A: GW 224 is manufactured from case hardened carbon steel with a Rockwell C35 minimum hardness specification. The case hardening process creates a hard outer surface that resists wear and rolling contact fatigue while maintaining a tougher core. This material composition is designed to withstand repetitive load cycles in manual pallet jack service.
Q: What bearing type is compatible with GW 224?
A: GW 224 is designed for sealed ball bearing wheels. The axle shaft diameter is precision machined to fit standard sealed bearing races used in pallet jack load wheels. Do not attempt to use open-race or roller bearings with GW 224; use only sealed ball bearings to maintain proper fit and load support.
Q: How is GW 224 finished and what maintenance does it require?
A: GW 224 has a machined finish applied during manufacturing. The case hardening and machining provide corrosion resistance suitable for typical warehouse and factory environments. No special coating maintenance is required. Wipe the axle clean of debris and inspect for cracks or bending during routine wheel maintenance. Apply light machine oil to the bearing seals periodically if the jack is used in humid or outdoor conditions.
Q: Can GW 224 be used as a direct replacement for worn load wheel axles?
A: Yes. GW 224 provides a precision fit and is designed as a direct replacement for original load wheel axles. Verify that your jack frame and bearing bore accept the GW 224 shaft diameter before installation. Once confirmed, installation is straightforward: remove the old axle, insert GW 224, and re-bolt the wheel assembly. No modification to the jack frame is required.
Q: What is the expected service life of a GW 224 axle?
A: A GW 224 axle typically lasts 3 to 5 years under normal intermittent manual pallet jack use in warehouse or light industrial environments. Service life depends on load frequency, load weight, maintenance of the bearings, and storage conditions. Inspect the axle annually for cracks, bending, or wear. Replace immediately if damage is found or if wheel operation becomes rough or binding.
