Frequently Asked Questions
Q: What is CT 51043753 and what equipment does it fit?
A: CT 51043753 is a polyurethane load wheel assembly with extended double-row bearing design for Caterpillar electric lift trucks. The assembly includes a precision steel bearing, alloy steel hub, and 97A durometer polyurethane tread. Fits multiple Caterpillar electric models.
Q: What are the material specifications for this load wheel?
A: Wheel core is steel with polyurethane tread compound at 97A hardness. Bearing material is precision sealed rolling element steel. Hub is precision-machined alloy steel. This construction provides durability for material handling applications.
Q: What is the difference between 97A hardness polyurethane and other grades?
A: 97A durometer represents the hardness rating of the polyurethane tread. Higher durometer values indicate harder compounds with greater load capacity and wear resistance but less floor grip. Lower values offer better traction but faster wear. 97A is a standard industrial load wheel specification.
Q: How long does this load wheel typically last?
A: Lifespan depends on equipment usage intensity, floor conditions, and maintenance. Polyurethane load wheels generally provide extended service life compared to rubber. Monitor for flat spots, uneven wear, or bearing noise to determine replacement timing.
Q: Does CT 51043753 have a cross-reference part number?
A: This is the Caterpillar OEM part number. If you need compatibility confirmation with other equipment brands or earlier model variations, provide your equipment details and we can confirm fitment.
