Frequently Asked Questions
Q: What is XL3 bonding technology?
A: XL3 bonding is a specialized adhesive and mechanical lock technology that bonds the polyurethane tread to the steel hub. This prevents separation between the tread and core, which is critical in heavy-duty cycle applications with high impact loads. Standard bonding can separate under extreme duty, causing wheel failure. The SU S9157-XL-A with XL3 bonding withstands the stress of continuous high-frequency operations without tread delamination.
Q: Is the SU S9157-XL-A compatible with Crown electric pallet jacks?
A: Yes, this wheel is designed for Crown pallet jacks and compatible equipment requiring a 5.00 inch diameter, 4.125 inch width wheel with a 2.125 inch bore. The manufacturer part number is L509157 with cross-references including L509157-CG, L509157CG-A2, L509157R, and L509157RA1. Verify your equipment specifications before ordering to ensure compatibility.
Q: What are the bore diameter and bore depth specifications?
A: The SU S9157-XL-A has a 2.125 inch bore diameter with a bore depth of 0.826 inch. These dimensions match standard Crown and compatible electric pallet jack axle shafts. Verify your axle diameter before purchasing; a 2.0 inch or 2.5 inch bore will not fit correctly. Measure the axle shaft to confirm compatibility.
Q: What load capacity does this wheel support?
A: The SU S9157-XL-A is rated for heavy-duty cycle tolerance designed for high-frequency applications. The exact load capacity depends on your equipment model nameplate, which typically ranges from 3000 to 5500 lbs total truck capacity. The XL3 bonding ensures the wheel can withstand sustained high-cycle loading without tread separation. Do not exceed your equipment nameplate capacity.
Q: How long does the SU S9157-XL-A wheel last in heavy-duty operations?
A: In heavy-duty high-cycle operations, expect 24 to 36 months of service life depending on operating conditions, surface terrain, and load consistency. Wheels used in lighter-duty environments may last longer. Regular inspection for tread wear and hub condition helps maximize lifespan. Replace wheels when tread thickness becomes visibly thin or tread separation appears.
Q: Can the SU S9157-XL-A be used in wet or corrosive environments?
A: The steel hub features specialized surface finishing designed to resist rust and corrosion. The polyurethane tread is naturally resistant to moisture and most common warehouse chemicals. However, prolonged exposure to extreme corrosive conditions (caustics, acids) may degrade both materials. Store wheels in dry conditions when not in use. Rinse with fresh water after exposure to salt or harsh chemicals.
