Frequently Asked Questions
Q: When should I use the SU S9135-XL-A-SS instead of the standard SU S9135-XL-A?
A: Use the SU S9135-XL-A-SS whenever your pallet jack operates in corrosive environments: wash-down areas, food processing facilities, chemical storage facilities, or coastal environments with salt spray. The stainless steel (SS) bearings resist rust and corrosion. Standard steel bearings in these conditions will seize and fail within weeks. Choose the SS variant if your facility cleans equipment with high-pressure washers or wet chemicals.
Q: What is the performance difference between SS bearings and standard steel bearings?
A: Both bearing types provide identical smooth rotation and load capacity when functioning correctly. The difference is corrosion resistance. Stainless steel bearings resist rust and maintain smooth operation in wet and chemically aggressive environments for the full assembly lifespan. Standard steel bearings will rust, stiffen, and ultimately seize if exposed to moisture or salt spray, requiring premature replacement.
Q: Is the SU S9135-XL-A-SS compatible with Crown electric pallet jacks?
A: Yes. The SU S9135-XL-A-SS maintains the same 3.25 inch diameter, 5 inch width, and 25mm bearing bore as the standard assembly. It is a direct bolt-on replacement for any Crown electric pallet jack or compatible equipment that accepts a 3.25 x 5 load wheel assembly.
Q: Can I replace only the bearings on my current SU S9135-XL-A-SS if they fail?
A: No. The bearings are pressed into the wheel hub and cannot be field-replaced without specialized bearing removal and installation tools. If the bearings fail, replace the entire SU S9135-XL-A-SS assembly. Attempting to remove or repair sealed bearings will damage the wheel hub and void the warranty.
Q: How long do stainless steel bearings last in a food processing environment?
A: In food processing wash-down environments, expect the SU S9135-XL-A-SS assembly to deliver 24-36 months of service before bearing wear becomes noticeable, assuming weekly cleaning with neutral detergent and proper rinsing. High-chlorine wash-down systems or continuous salt spray exposure may reduce this to 18-24 months. Inspect monthly for any grinding noise or resistance to rotation and replace if either develops.
Q: What is the cost difference between the SU S9135-XL-A-SS and the standard SU S9135-XL-A?
A: The SS variant costs approximately 20-30 percent more than the standard assembly due to stainless steel material and specialized manufacturing. In corrosive environments, this premium is justified by extended service life and reduced downtime from bearing failure. For dry indoor warehouse use, the standard assembly is cost-effective and sufficient.
