Frequently Asked Questions
Q: What Bishamon pallet jack models does this nylon-on-nylon roller fit?
A: This load roller assembly is designed for Bishamon BS-55 manual pallet jack models. The nylon-on-nylon hub configuration is specific to this frame type. Alternate model designations include BS55 and BS 55. Confirm your equipment serial and nameplate before ordering.
Q: What are the specifications for this nylon-hub wheel assembly?
A: The roller outer diameter is 2.75 inches. The hub is nylon construction with pre-installed sealed ball bearings and flexible rubber washers. The nylon hub reduces vibration and provides self-centering load distribution, making this assembly suitable for medium-duty warehouse applications.
Q: Why is flexible rubber washer material used in this assembly?
A: Flexible rubber washers absorb vibration and accommodate minor shaft misalignment, reducing stress on bearings. This design extends bearing life and provides smoother operation. The rubber material also isolates the nylon hub from metal components, minimizing noise.
Q: How does nylon-on-nylon hub construction affect performance?
A: Nylon hub construction is lighter than steel and reduces wear on fork tips during mounting. The nylon material provides self-lubricating characteristics, reducing friction and maintenance requirements. This design is optimized for manual pallet jack applications with moderate load cycles.
Q: What related part numbers should I reference for compatibility?
A: Related part numbers include BI 85007098-KIT (complete kit variant) and BI 85007098-A-D (variant assembly). Reference your existing parts documentation to confirm this nylon-hub version matches your equipment specification. Cross-check model designation BS-55 on your pallet jack.
Q: How long do sealed ball bearings last in this nylon-hub configuration?
A: Sealed ball bearings are pre-lubricated and engineered for extended service life in manual pallet jack duty cycles. The nylon hub and rubber washers reduce bearing stress, potentially extending lifespan. Replace if you observe excessive noise, play, or friction during operation.
