Frequently Asked Questions
Q: Is the SU 9135-EZ-A equivalent to the SU S9135-EZ-A and what are the cross-references?
A: Yes, the SU 9135-EZ-A is directly equivalent to SU S9135-EZ-A. Both part numbers refer to the same load wheel assembly with identical specifications and performance. The SU 9135-EZ-A also relates to the SU 9135-XL-A as a standard-duty variant compared to that models heavy-duty rating. For compatibility purposes, if you need a replacement wheel and see SU S9135-EZ-A on an old parts list, the SU 9135-EZ-A will fit directly. The GW 9135 is a generic equivalent that may be cheaper but verify OEM compatibility before substituting. Always use the manufacturer part number from your equipment documentation when ordering.
Q: What is the difference between the SU 9135-EZ-A standard wheel and the SU 9135-XL-A heavy-duty variant?
A: The SU 9135-EZ-A uses a 95A durometer polyurethane compound and is rated for standard pallet truck applications. The SU 9135-XL-A uses a 97A durometer Cushothane XL compound with XL3 bonding technology, making it harder and more abrasion-resistant for heavy-duty or high-speed operations. The XL-A variant lasts longer under demanding conditions such as outdoor use, continuous operation, or high-load environments. If your truck operates indoors on smooth floors with moderate loads, the EZ-A is sufficient and more economical. If operations are continuous, outdoors, or involve rough handling, upgrade to the XL-A for extended life and reduced replacement frequency.
Q: Does the SU 9135-EZ-A come with factory-installed sealed precision bearings?
A: Yes, the SU 9135-EZ-A comes with factory-installed sealed precision bearings. The bearings are pre-lubricated and sealed to prevent contamination and reduce maintenance. No bearing repacking or additional lubrication is required during the service life. The sealed design protects against dust and moisture, extending wheel performance in mixed environments. Do not disassemble the bearing assembly or attempt to relubricate, as this will compromise the seals and cause premature failure. If the wheel begins to squeak or shows resistance during rotation, the bearings may be damaged and the entire assembly should be replaced.
Q: What is the wheel diameter, width, and bore size of the SU 9135-EZ-A?
A: The SU 9135-EZ-A specification lists a 2-inch diameter by 3-5/8 inch width polyurethane wheel, though this appears to be a data entry discrepancy. Cross-referencing with related SU 9135 series models confirms the standard size is 3.25 inches outside diameter by 5 inches width. The inside bore diameter is 1.938 inches and the bore depth is 0.591 inches. The steel hub has a bore outside diameter of 2.0467 inches with a 35mm bearing bore. Contact the supplier with the SKU number to confirm exact wheel dimensions before installation, as a 2-inch wheel would not fit a 3.25-inch application.
Q: What compatibility should I verify before installing the SU 9135-EZ-A on my pallet truck?
A: Before installation, verify the following: (1) Your truck axle shaft diameter matches the bore inside diameter of 1.938 inches. (2) Your current wheels are 3.25 x 5 inches to ensure the new wheel fits without modification. (3) The axle mounting hardware and retention clips fit the wheel bore design. (4) Your truck is rated for 95A durometer wheels. If your truck manual specifies a softer wheel for traction, the EZ-A may not be appropriate. (5) Check the Superior 9135 series compatibility list in your equipment documentation. If your truck was built after 2010 and uses 3.25 x 5 wheels with standard bolt patterns, compatibility is very likely. When in doubt, contact your equipment manufacturer with the model and serial number.
Q: How should I install the SU 9135-EZ-A wheel assembly?
A: Installation steps: (1) Remove the axle retention clip or cotter pin from the existing wheel and slide the old wheel off the axle shaft. (2) Clean the axle shaft of any dirt or damage. If the shaft is rough or damaged, clean with sandpaper or use a shaft sleeve. (3) Slide the SU 9135-EZ-A wheel onto the axle, ensuring the bore seats fully on the shaft with no gaps. The wheel should slide on smoothly without force. (4) Install mounting washers on both sides of the wheel if required by your equipment design. (5) Install the retention clip, cotter pin, or bolts to secure the wheel axially. Tighten all fasteners firmly. (6) Spin the wheel by hand to verify smooth rotation with no binding, noise, or drag. If the wheel is tight or noisy, remove it and recheck the bore and shaft fit.
