Frequently Asked Questions
Q: What are the specifications of the BO 89-N load roller assembly?
A: The BO 89-N features a solid nylon tread with nylon hub construction. It includes dual 6204-2RS sealed ball bearings, a beveled tread profile for even wear distribution, and a non-marking surface suitable for both indoor and outdoor material handling operations.
Q: Which pallet jack models is the BO 89-N compatible with?
A: The BO 89-N load roller assembly is designed for Boman Model 55 manual pallet jacks. Confirm your equipment model before ordering to ensure correct fitment.
Q: What is the 2RS bearing seal designation?
A: The 2RS designation on 6204-2RS sealed ball bearings indicates rubber seals on both sides of the bearing. These seals protect against contamination and moisture ingress, extending bearing life in warehouse and outdoor environments.
Q: Why is the non-marking nylon surface important?
A: The non-marking nylon tread resists marking on polished concrete, epoxy, and sealed flooring common in retail and controlled storage areas. This feature prevents scuff marks or staining on sensitive floor surfaces.
Q: How does the beveled tread profile improve performance?
A: The beveled tread profile distributes load pressure evenly across the roller surface, reducing edge wear and extending assembly lifespan. This design improves longevity compared to flat-tread alternatives and maintains consistent performance over the service life of the assembly.
Q: Can the BO 89-N be used in outdoor environments?
A: Yes, the BO 89-N is rated for both indoor and outdoor material handling applications. The sealed bearing design and non-marking nylon construction provide protection against moisture and UV exposure in outdoor warehouse and yard operations.
Q: How does the BO 89-N compare to other Boman roller assemblies?
A: The BO 89-N offers solid nylon tread with nylon hub for non-marking applications and moderate-duty cycles. Boman also manufactures the BO 89-D with polyurethane tread and aluminum hub for heavy-duty industrial environments requiring greater durability and load capacity.
