Frequently Asked Questions
Q: What does SU 9531 offer as an upgrade or equivalent to SU 9531-A?
A: SU 9531 is a poly load wheel assembly equivalent to and supersedes SU9531-A. Both provide the same 2.50 inch diameter and 3.25 inch width specifications with polyurethane tread and electroplated carbon steel hub. SU 9531 is the current production part number, so use it for new orders; existing SU9531-A units can be replaced with SU 9531.
Q: What equipment is SU 9531 compatible with?
A: SU 9531 is designed for standard electric pallet truck models and electric lift trucks requiring a 2.50 x 3.25 poly load wheel. Verify your truck model and current wheel assembly part number against compatibility documentation before ordering. Incorrect wheel size causes fitment failure and unsafe operation.
Q: What are the load rating and operating specifications for SU 9531?
A: SU 9531 carries the load rating of the truck on which it is installed, up to the truck nameplate capacity. Operating specifications including maximum load per wheel, speed limits, and temperature ranges are defined by your truck manual. Do not exceed truck nameplate capacity, and do not operate the wheel outside manufacturer temperature or surface recommendations.
Q: How long will the SU 9531 polyurethane wheel last?
A: Polyurethane wheels typically last 3 to 5 years with regular maintenance and proper load management. Lifespan decreases with heavy-duty use, overloading, operation on sharp debris or broken surfaces, and inadequate bearing lubrication. Replace immediately if the wheel is flat-spotted, cracked, or no longer rolls smoothly.
Q: What is the advantage of the polyurethane tread on SU 9531?
A: Polyurethane tread provides good grip on smooth warehouse floors, resists cuts and tears better than rubber, and requires minimal maintenance. The material is also durable on concrete and does not easily track dirt or contaminate clean rooms. For heavy-duty outdoor use or rough surfaces, verify that polyurethane is appropriate before installation.
Q: Is the SU 9531 electroplated hub corrosion-resistant?
A: Yes, the electroplated carbon steel hub provides corrosion resistance suitable for indoor warehouse and manufacturing environments. For outdoor, wet, or saltwater-exposed applications, electroplating alone may not provide sufficient protection; consult Superior factory support for alternative hub materials or coatings appropriate to your operating environment.
