Frequently Asked Questions
Q: What is the difference between SU 9110-XL and SU 9109-XL?
A: SU 9110-XL and SU 9109-XL are different part numbers and are not interchangeable. SU 9110-XL is a separate design that may have different hub geometry, bearing specifications, or tread compound than SU 9109-XL. The 9110 designation indicates it is designed for a different truck model or application. Always use the exact part number your truck manufacturer specifies.
Q: Is SU 9110-XL a load wheel or a steer wheel?
A: SU 9110-XL is a load wheel assembly designed to support the pallets and main truck load. Check your truck documentation to confirm whether SU 9110-XL is used as a drive wheel, load wheel, or both. Using the wrong wheel type in the wrong position can cause uneven wear, steering problems, or safety hazards. Install each wheel assembly in the position specified by your truck manual.
Q: What bearing and tread specifications does SU 9110-XL have?
A: SU 9110-XL features sealed precision deep groove bearings and polyurethane tread optimized for extra-large wheel applications. The exact bearing size, tread thickness, and material grades may differ from SU 9109-XL variants. Refer to the technical specifications sheet for SU 9110-XL provided with the part or from your distributor for complete details.
Q: Can I use SU 9110-XL as a replacement for any standard wheel on my electric lift truck?
A: No. SU 9110-XL is a specific part designed for particular truck models or configurations. Substituting it for a standard wheel or different XL variant will cause fitment, alignment, or load distribution problems. Always verify your truck requires SU 9110-XL by checking the original part number from your truck documentation or contacting your truck manufacturer.
Q: How long does SU 9110-XL last before replacement?
A: SU 9110-XL has an expected lifespan of 2 to 4 years under normal warehouse conditions. Heavy-duty use, outdoor operation, or rough flooring will reduce lifespan to 18 months to 2 years. Indoor use on smooth concrete extends lifespan toward 4 years. Monitor tread wear every 3 to 6 months and replace when tread depth is less than one-quarter inch.
Q: What maintenance does SU 9110-XL require?
A: SU 9110-XL bearings are sealed and require no lubrication or repacking. Monthly, visually inspect the polyurethane tread for cuts, flat spots, or uneven wear patterns. Check the axle pin and cotter pin to ensure they remain secure. If the wheel wobbles, makes noise, or spins unevenly, stop using the truck and replace the wheel assembly. Do not attempt to repair a wheel with failed bearings.
