Product Description
LOAD WHEEL (6X2 POLY)
Frequently Asked Questions
Q: What does 6X2 POLY mean in the product designation SU S624?
A: 6X2 indicates the wheel dimensions in inches: 6 inch diameter by 2 inch width. POLY means the tread is made from polyurethane compound. This is a smaller wheel than the SU S621-XL (3.25 inch diameter) and narrower, making it suitable for different truck models or lighter-duty applications where a compact wheel is required.
Q: Is the SU S624 a load wheel or guide wheel and what is it rated for?
A: The SU S624 is a load wheel assembly based on standard naming conventions. The 6 inch diameter and 2 inch width are typical for medium-duty electric lift trucks. Verify the specific truck model compatibility in the OEM documentation before ordering, as wheel position and load rating depend on your truck frame design.
Q: Can I use the SU S624 to replace SU S621-XL wheels?
A: No. The S624 is 6 inches in diameter and 2 inches wide, while the S621-XL is 3.25 inches in diameter and 4.19 inches wide. These wheels are incompatible. Using a different size wheel will cause tilting, bearing stress, and load imbalance. Always install wheels that match your truck model specifications.
Q: What are the bearing specifications and bore size for the SU S624?
A: Bearing bore and material specifications for the SU S624 are not detailed in standard product documentation. Verify the bearing bore ID, axle bolt size, and hub width against your truck assembly manual before ordering. Incompatible bore sizes will prevent installation and cause safety issues.
Q: How long do polyurethane SU S624 wheels last and when should I replace them?
A: Polyurethane wheels typically last 3-5 years in commercial environments. Inspect monthly for tread wear, flat spots, or bearing movement. Replace if the wheel does not spin freely, if tread is worn more than 25 percent, or if bearing play is visible. Worn wheels reduce load stability and increase the risk of truck malfunction.
Q: Can I mix SU S624 wheels with other SU models on the same truck?
A: Only if all wheels on the same truck are the same diameter and width. Mixing different wheel sizes will cause the truck to tilt or lean, reducing stability and safety. If you have multiple trucks with different wheel sizes, do not interchange wheels between models.
