Frequently Asked Questions
Q: Does GW 534-A1 replace GW 534 and GW 534-A wheels?
A: GW 534-A1 is a superseding model that replaces GW 534-A as the current production standard. Both GW 534-A1 and GW 534-A have identical external dimensions (3.25 by 6.25 inches, 25mm bore) and are cross-compatible on the same truck platforms. GW 534-A1 is equivalent to Jungheinrich part number 51064639 for trucks from that manufacturer. For new replacements, specify GW 534-A1. Existing GW 534-A wheels continue to fit and function correctly.
Q: Is GW 534-A1 a non-marking wheel?
A: Yes. GW 534-A1 features a non-marking 95A durometer polyurethane tread, designed to leave no black marks or scuffs on polished warehouse floors or sensitive floor coatings. The tread is formulated to provide good traction without color transfer. Use GW 534-A1 on food service, pharmaceutical, or clean room applications where floor cleanliness is critical. Standard polyurethane wheels may mark floors; GW 534-A1 prevents this issue.
Q: What is the bearing bore and hub material of GW 534-A1?
A: GW 534-A1 has a 25mm (0.984 inch) bearing bore ID. The hub is machined carbon steel with a clear coat finish to protect against corrosion and moisture. The clear coat preserves steel color while offering moderate rust resistance. Do not use GW 534-A1 in high-humidity or outdoor environments for extended periods as the steel core can corrode. Store in dry conditions and inspect annually for rust formation.
Q: How do I diagnose if GW 534-A1 wheels are worn out?
A: Inspect tread depth monthly. Replace wheels when tread wears smooth or develops a flat spot exceeding 1/16 inch depth. Watch for uneven wear patterns, which may indicate misaligned bearings or truck chassis issues. Listen for squeaking or grinding noises when steering, suggesting bearing wear. Check the hub for cracks or separation from the polyurethane tread; bonding failure means the wheel must be replaced immediately. If tread separates or splits, do not use the wheel as it can suddenly fail under load.
