Frequently Asked Questions
Q: What are the specifications of the CR 072280-A load wheel assembly?
A: The CR 072280-A is a complete load wheel assembly measuring 5 inches in diameter with 4.12-inch tread width and 2.44-inch bore. It features a steel core with bonded polyurethane 95A compound 305 tread and includes a shoulder bearing for smooth rotation. This assembly is ready for mounting.
Q: What is the difference between CR 072280 and CR 072280-A?
A: The CR 072280 is a 3.25-inch wheel with cast iron core and 30mm bore. The CR 072280-A is a larger 5-inch assembly with steel core, 2.44-inch bore, and integrated shoulder bearing. The CR 072280-A is designed for heavy-load applications and different pallet jack models. Do not interchange these parts.
Q: Which Crown pallet jack models use the CR 072280-A?
A: The CR 072280-A is engineered for Crown electric pallet trucks rated for heavy-load warehouse applications. Verify your equipment model and serial number against Crown documentation. Bore diameter and bearing type must match your pallet jack axle configuration exactly.
Q: What does polyurethane 95A compound 305 mean?
A: The 95A shore hardness rating means the polyurethane is moderately hard, providing optimal balance between load capacity and traction. Compound 305 is a specific Crown formulation designed for electric pallet jack load wheels in warehouse environments. It resists abrasion, absorbs floor impact, and maintains grip in wet and cold storage areas.
Q: Does the CR 072280-A include a bearing?
A: Yes. The CR 072280-A includes an integrated shoulder bearing that allows the wheel to rotate freely on the axle. The bearing is sealed and maintenance-free. Do not remove or replace the bearing without proper equipment.
Q: How long does the CR 072280-A assembly last?
A: Under normal heavy-duty warehouse conditions with loads up to 5000 pounds, expect 3-5 years of service life. The steel core and quality bearing extend durability compared to smaller wheels. Worn tread or bearing noise indicates replacement is needed. The bearing will fail if wheel is overloaded or operated at high speed.
