Frequently Asked Questions
Q: What bearing size comes with the SU S9135-XL-A assembly?
A: The SU S9135-XL-A is pre-assembled with 25mm (0.984 inch) bore standard precision bearings. These bearings are installed and sealed at the factory. Do not attempt to remove or replace them unless the bearing makes noise or the wheel wobbles, indicating bearing failure.
Q: How do I install the SU S9135-XL-A assembly on my electric pallet jack?
A: The SU S9135-XL-A is designed as a drop-in replacement. Remove the axle pin or bolt from the jack frame. Slide the assembly onto the axle and insert the pin or bolt through the hub. Tighten securely and verify the wheel spins freely with no wobble or drag. If the wheel does not spin freely after installation, check that the axle is straight and the pin is fully inserted. Do not overtighten, as this will damage the bearings.
Q: What tools are needed to replace the SU S9135-XL-A?
A: Most installations require only a socket wrench or adjustable wrench to remove and secure the axle pin or bolt. If the axle pin is corroded, a penetrating oil like WD-40 applied 30 minutes before removal helps. No pressing or specialized bearing tools are needed; the assembly is pre-fitted.
Q: Can I use the SU S9135-XL-A if my jack uses stainless steel bearings?
A: The standard SU S9135-XL-A includes steel bearings. If your equipment specifications or environment requires stainless steel bearings (such as in wash-down areas or chlorine-rich environments), order the SU S9135-XL-A-SS variant instead. Steel bearings will rust and seize faster in corrosive environments and will void the warranty if used in salt or wash-down conditions.
Q: What is the load capacity of the SU S9135-XL-A assembly?
A: The SU S9135-XL-A wheel assembly is rated for the load capacity of your host electric pallet jack, typically 3000-5500 lbs depending on the jack model. The wheel itself does not limit capacity; capacity is determined by the jack frame and lift mechanism. Always verify your equipment nameplate for the maximum load rating before operating.
Q: How often should I inspect the bearings on the SU S9135-XL-A?
A: Check bearing condition monthly. Spin the wheel by hand; it should rotate smoothly with no grinding noise, squealing, or resistance. If you hear a grinding sound or feel roughness, the bearing is failing and the assembly must be replaced. Sealed bearings cannot be lubricated; once they fail, the entire assembly must be swapped out.
