Frequently Asked Questions
Q: Is SU 9133-A equivalent to SU 9133-XL-A?
A: Yes. SU 9133-A is a direct cross-reference equivalent to SU 9133-XL-A. Both are 3.250 inch by 3.250 inch load wheel assemblies with polyurethane tread construction. The SU 9133-A is marketed as a direct OEM replacement for the SU 9133-XL-A part number. Use them interchangeably on compatible equipment. Confirm fitment with your parts supplier.
Q: What material is the SU 9133-A tread made from?
A: The SU 9133-A features a 95A durometer polyurethane tread with Cushothane XL material specification. This hardness provides good grip and cut-tear resistance for warehouse and distribution center applications. The 95A durometer is slightly softer than premium 97A compounds, making it cost-effective for light to mid-duty cycles. It performs well on smooth and moderately textured floors.
Q: What is the alternate part number for SU 9133-A?
A: The alternate part number for SU 9133-A is SUS9133-XL-A. Both numbers represent the same 3.250 x 3.250 inch load wheel assembly. If you receive an invoice or parts list showing either number, they are the same component. Verify the alternate number with your supplier to avoid duplicate orders or confusion during inventory management.
Q: How long does the SU 9133-A last compared to premium 97A wheels?
A: The SU 9133-A with 95A durometer polyurethane typically lasts 2 to 3.5 years in active service. Premium 97A durometer wheels often last 3 to 5 years. The difference is most noticeable in high-cycle applications and rough floor environments. For light to moderate use on smooth floors, the SU 9133-A provides comparable life at lower cost. Inspect quarterly for tread wear and replace when grip diminishes.
Q: Does the SU 9133-A require bearing maintenance?
A: No. The SU 9133-A uses sealed precision ball bearings that are maintenance-free for life. Do not attempt to add lubricant to the seal, as this can damage the bearing races and cause premature failure. If rotation becomes stiff or noisy after installation, the wheel was likely over-tightened during axle bolt installation. Loosen the bolt slightly to restore smooth rotation, or replace the wheel if bearings are damaged.
