Frequently Asked Questions
Q: What is the CR 121500-001 poly assembly and what does it fit?
A: The CR 121500-001 is an OEM poly assembly with hub for Crown electric lift trucks. This component is a load-bearing wheel or roller assembly made from polyurethane material and designed to support and guide the truck during operation. The hub provides the mounting interface to the truck frame or steering system.
Q: What material is the CR 121500-001 poly assembly made from?
A: The CR 121500-001 is manufactured from polyurethane, a durable elastomer engineered for material handling applications. Polyurethane offers good load-bearing capacity, resistance to oils and moisture, and moderate rebound properties. The material provides reliable performance across standard warehouse and industrial environments.
Q: How does the hub configuration affect fitment of the CR 121500-001?
A: The hub is the mounting interface between the poly wheel or roller and the truck frame. Hub dimensions, bore size, and bolt pattern must match the truck steering system or frame attachment points exactly. Verify hub diameter, shaft bore, and mounting configuration against your truck specifications before ordering to ensure proper fitment and alignment.
Q: What is the typical lifespan of the CR 121500-001 poly assembly?
A: Lifespan depends on truck load, usage intensity, and environmental conditions. Polyurethane wheels and rollers in standard material handling operations typically last 1-3 years before wear or damage requires replacement. Inspect regularly for flat spotting, cracks, hub separation, or excessive wear that reduces load-bearing capacity.
Q: What maintenance or care does the CR 121500-001 require?
A: Periodically clean debris and buildup from the poly surface. Inspect the hub fasteners and mounting bolts for looseness. Check for cracks or damage to the polyurethane. Monitor bearing condition if the assembly includes integral bearings. Remove the assembly from service if the hub shows signs of damage, separation, or misalignment that compromises wheel tracking.
