Frequently Asked Questions
Q: What is included in SU 854-A and how does it differ from SU 854?
A: SU 854-A is a complete load wheel assembly with pre-installed bearings. It includes the 5.000 inch x 2.875 inch Cushothane XL wheel core plus sealed bearings ready for axle installation. SU 854 is the wheel core alone and requires separate bearing installation.
Q: Can SU 854-A be installed directly onto an electric lift truck axle without modification?
A: SU 854-A will fit standard electric lift truck axles with a 2.25 inch inside bore. However, verify the axle diameter matches the bore and that the truck load capacity exceeds the load you will carry. If the axle is damaged, bent, or has a different diameter, the wheel will not roll straight and may cause equipment failure.
Q: What is the installation procedure for SU 854-A on a lift truck?
A: Lower the truck to the ground and support it safely with blocking. Slide SU 854-A onto the axle until the bearing seats fully against the axle shoulder. The wheel should spin freely by hand with no lateral movement. If the wheel binds or has side-to-side play, the axle is incorrect or damaged. Do not operate the truck until all wheels roll freely.
Q: Are the bearings in SU 854-A sealed or do they require lubrication?
A: The bearings are sealed and do not require lubrication during normal service. Inspect the wheels every 250 operating hours. If you hear grinding noise, feel excessive friction, or observe the wheel not spinning freely when the truck is lifted, the bearing has failed and the assembly must be replaced.
Q: What is the expected service life of SU 854-A in typical warehouse operations?
A: Typical service life is 12 to 24 months depending on load weight, floor surface, and daily operating hours. In high-duty operations with heavy loads on rough concrete, expect 6 to 12 months. Replace the assembly when the wheel diameter is worn more than 0.25 inches below 5.000 inches or when the tread becomes flat.
Q: If the bearing fails on SU 854-A, can the bearing be replaced separately or must the entire assembly be replaced?
A: The bearing is pressed into the hub and cannot be removed without damaging the polyurethane wheel. Replace the entire SU 854-A assembly when the bearing fails. Attempting to drill out or press out a bearing will destroy the wheel and create safety hazards.
