Frequently Asked Questions
Q: What is the CT 51043753 and what equipment does it fit?
A: The CT 51043753 is a polyurethane load wheel assembly with extended double-row bearing design for Caterpillar electric lift trucks. The assembly includes a precision sealed bearing, alloy steel hub, and 97A durometer polyurethane tread. Fits multiple Caterpillar electric pallet jack and lift truck 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 with hardened races. Hub is precision-machined alloy steel. This construction provides durability for material handling applications.
Q: What is 97A durometer hardness and why does it matter?
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 reduced floor grip. Lower values offer better traction but faster wear. 97A is a standard industrial load wheel specification for heavy-duty warehouse use.
Q: How long does this load wheel typically last?
A: Lifespan depends on equipment usage intensity, floor conditions, and maintenance practices. Polyurethane load wheels generally provide extended service life compared to rubber alternatives. Monitor for flat spots, uneven wear patterns, or bearing noise to determine replacement timing.
Q: Can I use this wheel on non-Caterpillar equipment?
A: Wheel compatibility depends on hub diameter, bearing size, and axle configuration. While the CT 51043753 is designed for Caterpillar equipment, cross-brand fitment may be possible with compatible specifications. Contact us with your equipment details for compatibility confirmation.
Q: Does this assembly come with bearings pre-installed?
A: Yes, the CT 51043753 is a complete load wheel assembly with bearings pre-installed, sealed, and greased. It is ready for direct installation on compatible Caterpillar equipment.
