Frequently Asked Questions
Q: What is the part history and current equivalent for the SU S9131-XL?
A: The SU S9131-XL is the original part designation for Superior XL platform load wheels. It has been superseded by the SU S9131-XL-A designation. Both parts are functionally identical 8x4 polyurethane wheels with 97A durometer hardness and sealed bearings. The SU S9131-XL-A is the current recommended replacement.
Q: What cross-reference part numbers match the SU S9131-XL?
A: The SU S9131-XL is equivalent to SUS9131-XL, SUS9131XL, S9131XL, 9131XL, and replaces the earlier 9131-XL designation. Current equivalent is SU S9131-XL-A. When ordering, confirm the exact SKU with your supplier as similar-looking numbers can refer to different component configurations.
Q: Does the SU S9131-XL come with bearings or is it a wheel-only component?
A: The SU S9131-XL is available in two configurations: wheel-only (requires separate bearing installation) or with pre-pressed sealed bearings. Check your purchase documentation and package labeling. If you receive wheel-only but need a bearing assembly, contact your supplier for the correct part or order the SU S9131-XL-A with integrated bearings.
Q: How does the SU S9131-XL perform on concrete versus tile or smooth floors?
A: The 97A durometer polyurethane tread provides excellent grip and durability on rough concrete and textured floors typical of warehouse use. On smooth tile, polished concrete, or slick epoxy floors, grip may be reduced and the wheel is prone to faster wear from increased sliding friction. Consider softer durometer alternatives (like 85A) for very smooth floors, but 97A is the standard for mixed-surface industrial use.
