Frequently Asked Questions
Q: What is the difference between SU S9150-A and SU S9150?
A: Both SU S9150-A and SU S9150 share identical outer dimensions (5 x 2.875 inches) and the same Cushothane XL material. The -A designation indicates a variant sourcing or specification revision. Before ordering a replacement, confirm which variant your pallet jack originally used by checking the part stamp on the existing wheel or consulting your parts supplier.
Q: Can SU S9150-A be installed on a wet floor or cold storage application?
A: SU S9150-A is not specifically engineered for wet floors or cold storage. If your pallet jack operates in wet or freezing environments, the polyurethane compound may lose traction and the bond to the hub can deteriorate in sustained cold. For these applications, use a high-traction variant such as SU S9150-EZ, which features a specialized polyurethane compound designed for wet and cold conditions.
Q: What are the bearing specifications for the SU S9150-A wheel?
A: The bearing specifications depend on your pallet jack axle assembly and are not included with the wheel itself. The bore outside diameter of SU S9150-A is 2.4384 inches. Consult your pallet jack manual for the correct bearing size, type (ball or roller), and lubrication requirements. Use only grease-packed or sealed bearings rated for material handling equipment.
Q: How do I identify when SU S9150-A needs replacement?
A: Replace SU S9150-A when tread wear reaches 1/4 inch depth or less, flat spots appear on the wheel surface, cracks develop in the polyurethane tread or the hub bond separates from the steel core. If the wheel no longer tracks straight or causes vibration during operation, inspect for internal hub damage and replace immediately to prevent axle damage and safety hazards.
Q: What is the typical service life of SU S9150-A in a standard warehouse?
A: Under normal warehouse conditions with routine maintenance, SU S9150-A wheels typically last 18 to 36 months. Life varies based on floor surface, load weight, and daily usage hours. Smooth concrete floors and proper bearing lubrication extend service life. Rough or dirty floors, heavy loads, and poor maintenance reduce life significantly. Establish a quarterly inspection schedule to monitor wear.
