Frequently Asked Questions
Q: What does the -A designation mean on the SU 627-XL-A?
A: The -A designation indicates this is a dual tandem load wheel assembly with two polyurethane wheels bonded to a steel core hub. The assembly comes as a complete unit (approximately 2.44 inch total tread width) ready for installation on compatible electric lift truck models that require tandem wheel configurations.
Q: Is the SU 627-XL-A compatible with single-wheel applications?
A: No. The SU 627-XL-A is a dual tandem assembly and cannot be used as a single wheel replacement. If your jack requires a single wheel, use the SU 627-XL (non-A model). Do not attempt to separate the tandem wheels from the hub, as this will damage the bonding and the assembly.
Q: What core material is used in the SU 627-XL-A and why?
A: The SU 627-XL-A uses a finished steel core constructed to maximize bond integrity between the polyurethane tread and the hub. The finished steel (mill finish) provides optimal surface preparation for the XL3 bonding system. This design prevents wheel separation under heavy loads typical in warehouse environments.
Q: What are the bore specifications for the SU 627-XL-A installation?
A: The SU 627-XL-A has a 1.938 inch inside diameter with a 2.0467 inch bore outer diameter and 0.591 inch bore depth. Verify that your lift truck axle matches these specifications before installation. Improper bore sizing can result in wheel wobble and accelerated wear.
Q: How should the SU 627-XL-A be maintained to extend service life?
A: Inspect the assembly monthly for cracks, flat spots, and separation between the two wheels. Clean debris from between the tandem wheels to prevent corrosion of the steel core. If one wheel shows damage, you must replace the entire assembly because the wheels are permanently bonded and cannot be separated. Rotate the assembly to opposite positions every 6 months to equalize wear.
