Frequently Asked Questions
Q: What Crown pallet jack models does the SU 351 wheel fit?
A: The SU 351 polyurethane load wheel is engineered for Crown PC, PE, PR, and PW series electric lift trucks. Always verify your truck model prefix and serial range before ordering to ensure compatibility, as Crown production variants can have different load wheel specifications.
Q: What are the key dimensions and material specs for the SU 351?
A: The SU 351 features a 3.25 inch diameter, 2.44 inch tread width, 2.047 inch bore size, and polyurethane construction with 93A Shore A hardness. The 93A durometer rating provides good load capacity for moderate duty cycles without excessive heat buildup.
Q: Is the SU 351 available in higher durometer ratings for heavier duty?
A: The SU 351 comes in standard 93A durometer only. If you need higher load capacity or extended wear life, consider the SU 351-A, which uses Cushothane XL material at 97A durometer with a larger 5 inch diameter and HeatSink aluminum hub for thermal management.
Q: What is the typical lifespan of a polyurethane load wheel like the SU 351?
A: Polyurethane load wheels typically last 12-24 months depending on usage intensity, floor surface abrasiveness, and load profile. Standard 93A wheels wear faster under continuous heavy loading. Inspect quarterly for flat spots, edge chipping, or bore wear. Replace when diameter loss exceeds 0.125 inch or bore clearance becomes loose.
Q: Can I replace just one load wheel on my Crown truck?
A: It is not recommended to replace only one wheel. Unmatched wheel diameters cause steering drift and uneven load distribution. Replace both front load wheels as a pair. If the remaining wheels show significant wear, replace all four wheels to prevent accelerated bearing wear and ensure safe handling.
