Frequently Asked Questions
Q: What are the dimensions and bore size of the KA 78730186 load wheel?
A: The KA 78730186 is a precision-machined load wheel with a 3.25 inch diameter and 5.00 inch width. The bore size is 2.047 inch. These dimensions make it compatible with Komatsu electric lift truck models that use this standard bore size.
Q: What material is the KA 78730186 wheel made from and how durable is it?
A: The KA 78730186 features a polyurethane tread bonded to a machined steel core. The polyurethane tread has a nominal hardness of 93 Shore A, which provides balanced durability for general material handling applications. The steel core ensures structural integrity under load.
Q: Is the KA 78730186 a complete wheel assembly or just the wheel body?
A: The KA 78730186 is the wheel body only, not a complete assembly. It does not include bearings or a hub. If you need a fully assembled load wheel with bearings and hub, consider the KA 78730186-A assembly option.
Q: What equipment brands and models use the KA 78730186 load wheel?
A: The KA 78730186 is designed for Komatsu electric lift trucks. Before ordering, verify that your equipment uses a 2.047 inch bore and accepts a 3.25 inch by 5.00 inch wheel to ensure proper fitment.
Q: How long can I expect the KA 78730186 polyurethane tread to last?
A: Polyurethane tread lifespan depends on load, floor conditions, and usage frequency. The 93 Shore A hardness of this wheel provides moderate wear resistance. Wheels used on rough concrete or with heavy continuous duty will wear faster than those used in light-duty or controlled environments. Regular inspection will help you track wear and plan replacement.
Q: Can I use the KA 78730186 on wet floors or in cold storage?
A: The KA 78730186 has a standard 93 Shore A polyurethane tread, which is adequate for dry indoor use. For reliable traction on wet floors, cold storage environments, or slippery surfaces, a higher-durometer polyurethane compound is recommended. Check if a higher-performance variant is available for your specific application.
