Frequently Asked Questions
Q: Is the SU S627-XL-A equivalent to the SU S627-XL, and can they be used interchangeably?
A: Yes, the SU S627-XL-A is equivalent to the SU S627-XL. Both wheels share the same nominal dimensions (3.25-inch diameter x 2-inch width) and 97A durometer polyurethane tread. The primary difference is the hub material: the SU S627-XL-A features a HeatSink aluminum hub while the standard SU S627-XL uses a machined steel hub. Both are interchangeable if your jack hub is compatible with either material.
Q: What advantage does the HeatSink aluminum hub provide on the SU S627-XL-A?
A: The HeatSink aluminum hub dissipates heat more efficiently than steel during high-cycle operations. Improved heat dissipation extends wheel and bearing lifespan in applications with heavy load cycles. The aluminum hub is also lighter than steel, reducing overall jack weight slightly. In corrosive environments, aluminum can be more susceptible to oxidation unless properly sealed.
Q: What bearing configurations are available for the SU S627-XL-A?
A: The SU S627-XL-A is available in greaseable (Z) and non-greaseable sealed (2RS) bearing configurations. Greaseable bearings (Z) require re-lubrication every 6 to 12 months and are preferred in dusty environments where sealed bearings might trap contaminants. Sealed bearings (2RS) are maintenance-free and recommended for clean warehouse operations. Specify your required configuration when ordering.
Q: What does the XL3 chemical bonding mean for wheel durability and maintenance?
A: XL3 chemical bonding locks the polyurethane tread directly to the aluminum hub, eliminating the risk of tread separation under stress. This bonding method significantly extends wheel life in high-cycle applications. XL3-bonded wheels do not require special maintenance beyond standard bearing care. However, if tread damage occurs, the wheel cannot be re-tread and must be replaced as a complete assembly.
Q: How do I install the SU S627-XL-A on my electric pallet truck?
A: The SU S627-XL-A includes pre-installed precision bearings and is press-fit ready. Remove the old wheel and inspect the axle for debris or damage. Press the new wheel assembly onto the axle using proper bearing pressing equipment or a hydraulic press. Do not impact the wheel with a hammer or mallet, as this damages bearings and the hub. Ensure the wheel spins freely without binding after installation. If you lack pressing equipment, contact your maintenance technician or parts supplier for installation support.
