A: The CR 813128 features a polyurethane wheel with 95-A durometer hardness, and the integrated precision bearing system is engineered for heavy-duty material handling applications with sealed bearing surfaces to prevent contamination in industrial environments.
Q: What part numbers can I use to identify or order this product?
A: This assembly is identified by part number CR 813128. Additional cross-reference numbers include CR813128, 813128, and Crown 813128. When searching supplier catalogs or parts databases, any of these numbers will locate the same product.
Q: How long can I expect this caster wheel assembly to last?
A: High-resilience 95-A polyurethane wheels typically provide service depending on floor surface, load weight, and equipment runtime. Regularly inspect for uneven wear, flat spots, cracking, or bearing noise. Replace wheels when tread depth falls below or when wheels no longer rotate freely without wobbling or grinding.
Q: What maintenance is required for the CR 813128 caster wheel?
A: Periodically inspect the wheel for damage, worn tread, or bearing issues. Keep the bearing area clean and free from debris. Verify the assembly rotates smoothly without excessive side play. If the wheel becomes flat-spotted, develops cracks, or the bearing develops noise, schedule immediate replacement to maintain equipment safety and performance.
