Frequently Asked Questions
Q: What is the difference between HY 1457073 and HY 1457073-SG?
A: The HY 1457073-SG includes integrated string guards not present on the standard HY 1457073. The string guard variant is designed to prevent debris and strapping material from catching on the wheel during material handling operations.
Q: What wheel material is used in the HY 1457073-SG?
A: The HY 1457073-SG features Durarun 95A polyurethane construction. The 95A durometer rating provides a balance of load-bearing capacity and floor grip suitable for standard warehouse and pallet jack applications.
Q: Which Hyster models is the HY 1457073-SG compatible with?
A: The HY 1457073-SG is a direct OEM replacement component for Hyster W60Z, W80Z, B60Z, and B80Z series electric pallet truck models. Verify your truck model and serial range before ordering.
Q: Does the HY 1457073-SG include mounting hardware?
A: Yes, the HY 1457073-SG complete assembly includes mounting hardware for installation on electric pallet jack stabilizer positions. All fasteners are included with the caster wheel assembly.
Q: What performance advantage does Durarun 95A polyurethane offer?
A: Durarun 95A polyurethane offers increased wear resistance and load-bearing capability compared to softer compounds. The 95A durometer is engineered to withstand repeated impacts and sustained loads typical in pallet jack operations while maintaining floor contact.
Q: When should the HY 1457073-SG be replaced?
A: Replace the HY 1457073-SG when the polyurethane wheel shows flat spots, severe wear, or loss of floor grip, or when the caster assembly develops play or noise during operation. The 95A polyurethane will degrade faster under cold storage or wet floor conditions.
