Frequently Asked Questions
Q: What are the complete specifications for the SU S9144-XL load wheel?
A: The SU S9144-XL is a 3.25-inch outer diameter by 4.5-inch width polyurethane load wheel rated 97A durometer. Bore diameter is 1.938 inches with a 0.512-inch bore depth. Bore outside diameter is 2.1649 inches. The wheel features Cushothane XL polyurethane tread material, a steel hub with surface finishing, and XL3 proprietary bonding technology. Metric equivalent is 82.55mm diameter by 114.30mm width. The smooth-tread design provides optimal traction in material handling applications.
Q: What is XL3 bonding technology and how does it improve wheel life?
A: XL3 is a proprietary bonding adhesive that bonds the polyurethane tread permanently to the steel hub. XL3 technology guarantees no bond separation under normal duty cycles for the wheel lifespan. Standard polyurethane wheels rely on inferior bonding methods that fail under stress, causing the tread to separate from the hub. XL3 bonded wheels deliver 2 to 3 times longer service life and prevent catastrophic failure during operation.
Q: What are the cross-reference and equivalent part numbers for the SU S9144-XL?
A: The SU S9144-XL cross-reference part numbers include S9144-XL, SU S9144-XL-A, OL2295, PL123, and 5386. Equivalent OEM part number is L509144. When ordering replacement wheels, use the exact SKU SU S9144-XL to ensure you receive the XL3 bonded wheel. Other similar-looking part numbers may use different bonding technology or material grades and will not provide equivalent performance.
Q: Which equipment models and serial ranges are compatible with the SU S9144-XL?
A: The SU S9144-XL fits material handling equipment with fitment codes OL2295, PL123, and 5386 within specific manufacturing serial ranges. Compatibility varies by manufacturer and production year. Always verify your equipment model number, fitment code, and serial number range before ordering. Contact your equipment supplier or check the equipment nameplate to confirm serial number compatibility. Cross-model fitment outside these codes is not recommended.
Q: How do I diagnose wheel wear or failure on the SU S9144-XL?
A: Rotate the wheel by hand and listen for grinding, squeaking, or other noise. Inspect the tread surface for flat spots, cracking, or uneven wear patterns. Check the hub and tread interface for visible separation or gaps. If the wheel pulls to one side during operation or feels wobbly, the bearing may be worn or the hub fastener may be loose. Replace the wheel if tread depth is less than 0.25 inches, if cracks appear, or if any separation is visible.
Q: What is the difference between the SU S9144-XL wheel and the SU S9144-EZ-A assembly?
A: The SU S9144-XL is a wheel-only product with standard polyurethane and XL3 bonding, optimized for normal warehouse environments. The SU S9144-EZ-A is a complete wheel assembly that includes bearings and fasteners, with High Traction polyurethane optimized for wet and cold environments. Choose the SU S9144-XL if you have existing hubs and bearings or operate in dry warehouses. Choose the SU S9144-EZ-A if you need a complete assembly or operate in cold storage or wet areas.
