Frequently Asked Questions
Q: What material is the tread on the HY 4613509-SG caster wheel, and what does 95A durometer mean?
A: The HY 4613509-SG features a 95A grade polyurethane tread. The 95A durometer rating indicates the hardness of the polyurethane compound. This hardness level provides good load capacity while maintaining traction on concrete and warehouse floors. Higher durometer polyurethane (95A) resists wear better than softer compounds and is suitable for standard material handling conditions.
Q: Will the HY 4613509-SG caster wheel fit other lift truck brands, or is it Hyster-specific?
A: The HY 4613509-SG is engineered for Hyster lift truck applications. While the specific string-guard configuration may not be a direct fit for other brands such as Toyota, Crown, or Raymond, the core wheel and bearing assembly may be dimensionally compatible with certain equipment. Verify the mounting bore, wheel diameter, and guard attachment points on your equipment before ordering to confirm fitment.
Q: What is the purpose of the integrated string guards on this caster wheel?
A: The integrated string guards, made from polypropylene or steel depending on revision, are designed to deflect packing material, straps, and debris away from the wheel. This reduces wrap-around damage that can occur when string or packaging material catches on the wheel during material handling operations, extending wheel life and reducing maintenance issues.
Q: Does the HY 4613509-SG come pre-lubricated, or will it need bearing maintenance?
A: The HY 4613509-SG comes with factory pre-lubricated sealed ball bearings. The precision sealed design means the bearing is maintenance-free and does not require additional lubrication during normal warehouse operation. The sealed bearing prevents dust and contamination ingress, which extends bearing life and reduces downtime.
Q: What are the cross-reference part numbers for the HY 4613509-SG?
A: Cross-reference part numbers for the HY 4613509-SG include HY 4613509, HY4613509, and HY-4613509. These variations represent the same part number with different formatting conventions used across OEM documentation and supplier systems. When ordering, use the exact SKU HY 4613509-SG to ensure you receive the string-guarded configuration.
Q: What is the typical lifespan of the HY 4613509-SG caster wheel under normal warehouse conditions?
A: Under typical warehouse conditions with moderate-cycle loading (8-12 hours per day), the 95A polyurethane tread on the HY 4613509-SG generally lasts 12-24 months. Lifespan depends on floor type, load weight, and usage patterns. Wet or oily floors accelerate wear. Monitor for tread wear, flat-spotting, and bearing noise as indicators that replacement is needed.
