Frequently Asked Questions
Q: What is the BI 12061323-N-A and which Bishamon models does it fit?
A: The BI 12061323-N-A is a 3.25-inch diameter nylon load roller assembly engineered for Bishamon BS-55 and BS-65 manual pallet jacks. It features integrated sealed ball bearings and is constructed from high-impact nylon with chrome steel bearing components. Cross-references include 12061323-A, BS12061323-A, BI12061323-A, and it supersedes 12061323-A-D on select models.
Q: How does nylon tread compare to polyurethane options?
A: Nylon tread is lighter, less cost-intensive, and performs well on smooth, climate-controlled warehouse floors. High-impact nylon resists some abrasion but does not match the durability or grip of polyurethane (Ultra Poly or 70D variants). Nylon is suitable for standard manual jack applications with moderate load cycles; choose polyurethane for heavy-duty or high-traffic environments.
Q: What bearing materials and specifications does this assembly use?
A: The BI 12061323-N-A uses chrome steel bearing components in sealed ball bearing assemblies. Chrome steel provides corrosion resistance and smooth operation. Bearings are sealed and cannot be serviced; replace the entire assembly when bearings fail or exhibit noise or excessive friction during jack operation.
Q: What is the typical service life for this nylon roller?
A: Under normal warehouse use on standard floors, the BI 12061323-N-A delivers 1.5 to 3 years of service life. Abrasive floors, high-frequency load cycles, or rough handling reduces lifespan to 1 to 2 years. Replace when you observe visible wear, flat spots, cracking, or loss of grip. Sealed bearings cannot be serviced.
Q: What cross-references and superseded parts apply to this unit?
A: The BI 12061323-N-A is equivalent to 12061323-A, BS12061323-A, and BI12061323-A. It supersedes the older 12061323-A-D designation on compatible model years. Cross-reference alternatives include BI 12061323-A-SUPER and BI 12061323-S-A, depending on your specific Bishamon model and tread preference.
Q: Can I retrofit this nylon assembly to equipment originally equipped with polyurethane?
A: The BI 12061323-N-A has identical mounting geometry (3.25-inch diameter) to polyurethane variants and will physically fit. However, nylon offers less grip and durability than polyurethane. If your equipment was originally fitted with polyurethane, use nylon only if floor conditions are smooth and load cycles are light. Heavy-duty applications should remain on polyurethane or 70D variants.
