Frequently Asked Questions
Q: Is the SU 351-XL equivalent to the SU 351-A?
A: Yes. The SU 351-XL is an equivalent part number for the SU 351-A. Both reference the same 5 inch diameter Cushothane XL polyurethane load wheel with HeatSink vented aluminum hub and pre-pressed sealed bearings. The designation XL indicates high-durometer, extended-life construction.
Q: What is the physical specification for the SU 351-XL load wheel?
A: The SU 351-XL is a 5 inch diameter by 2.625 inch width load wheel. It uses Cushothane XL polyurethane at 97A durometer hardness with a vented aluminum hub and sealed bearing assembly. This configuration supports high-cycle industrial duty without the heat-related wear issues of standard polyurethane wheels.
Q: What is the bore size on the SU 351-XL?
A: The bore size on the SU 351-XL is 2.047 inch ID, matching standard electric lift truck axle specifications. Verify your truck axle diameter before purchase. If your truck uses a 1.5 inch or metric bore, contact customer service for alternative part numbers.
Q: Does the SU 351-XL come with pre-installed bearings?
A: Yes. The SU 351-XL comes with pre-pressed sealed bearings factory-installed. Do not attempt to remove or repack these bearings. The sealed design protects against water, dirt, and floor contaminants. If bearings fail or become noisy, replace the entire wheel assembly rather than attempting bearing service.
