Frequently Asked Questions
Q: What are the cross-reference part numbers for the SU S9157 XL?
A: The SU S9157 XL has multiple equivalent part numbers including SU S9157-XL-A, SUS9157XL, SUS9157X, and SU 9157-EZ-A. When ordering as a replacement, specify the exact SKU to ensure you receive the high durometer XL variant. Verify the OEM part number in your equipment documentation for compatibility confirmation.
Q: What is the difference between SU S9157 XL and the standard SU S9157?
A: The SU S9157 XL features a steel core with high durometer polyurethane tread, providing superior load handling and extended wear life compared to the standard SU S9157. The XL variant is designed for heavy-duty electric lift truck applications where higher puncture resistance and durability are required. Both share the same 5.0 x 4.12 inch dimensions and bore specifications.
Q: Is the SU S9157 XL suitable for wet floor or cold storage use?
A: The SU S9157 XL is engineered for standard warehouse duty cycles. If your equipment operates in wet floors or cold storage environments, use the SU 9157-EZ-A variant instead, which features a high traction polyurethane compound specifically formulated for those conditions. The EZ designation indicates enhanced grip on slippery surfaces and low-temperature performance.
Q: What are the bore diameter specifications for the SU S9157 XL?
A: The SU S9157 XL has a bore diameter of 2.441 inches with a bore depth of 0.826 inches and a bore outside diameter of 2.4406 inches. These specifications must match your axle configuration precisely. Measure your current wheel bore before ordering to confirm compatibility with your lift truck hub.
Q: How do I install the SU S9157 XL wheel on my electric lift truck?
A: Remove the retaining nut or snap ring from the axle. Slide the SU S9157 XL wheel onto the axle, aligning the 2.441 inch bore with the hub. Secure with the original retaining hardware, ensuring the wheel is fully seated. Spin the wheel by hand to verify free rotation. Do not over-tighten the retaining nut, as this can damage the bore and restrict wheel movement.
Q: What is the expected lifespan of an SU S9157 XL wheel in heavy-duty service?
A: The SU S9157 XL, with its steel core and high durometer polyurethane, typically lasts 3-5 years in heavy-duty electric lift truck operations. Actual lifespan depends on daily usage hours, floor conditions, and load consistency. Inspect wheels regularly for wear and replace if you observe tread separation, cracking, flat spots, or loss of material.
