Frequently Asked Questions
Q: What are the exact dimensions of the SU 641-XL-A?
A: The SU 641-XL-A has an outer diameter of 5.00 inches, tread width of 4.12 inches, and inner bore diameter of 2.44 inches. These dimensions fit electric lift trucks and pallet jacks that require an XL-width load wheel. Always verify your equipment bore and mounting clearance before ordering.
Q: What material is the SU 641-XL-A wheel made from?
A: The SU 641-XL-A features a high-durability polyurethane tread bonded to a machined steel core. This combination provides excellent wear resistance, load capacity, and impact absorption in warehouse and cold storage environments. The integrated shoulder bearings ensure smooth, low-friction operation.
Q: Does the SU 641-XL-A have sealed bearings?
A: Yes. The SU 641-XL-A is designed with integrated shoulder bearings that are sealed for protection against moisture and contaminants. This design is ideal for wet storage areas and environments where the wheel may be cleaned with water or exposed to humid conditions.
Q: How long does the SU 641-XL-A last before needing replacement?
A: In standard warehouse conditions, expect 18 to 36 months of service depending on load class, hours of operation per week, and floor surface. Rough concrete, outdoor use, and high-temperature cold storage reduce lifespan. Monitor for noise, vibration, or tread wear every 6 months.
Q: Can I use the SU 641-XL-A as a replacement on a different brand lift truck?
A: Cross-compatibility depends on the target equipment bore size, axle pin diameter, and mounting width. The 2.44-inch inner diameter and 4.12-inch tread width are common on many OEM brands. Verify the exact model and serial range of your equipment before ordering. We can help match specifications.
