Frequently Asked Questions
Q: What is the LJ 450-A and what equipment does it fit?
A: The LJ 450-A is a complete load roller assembly for Lo-Jo manual pallet jack model 5000. It includes a 3 inch diameter polyurethane tread, die-cast aluminum hub, and integrated sealed ball bearings designed for continuous industrial service.
Q: What are the material specifications for the LJ 450-A?
A: The hub is A380 die-cast aluminum per ASTM B85 for strength and corrosion resistance. Hardware is carbon steel per SAE J403. The 3 inch polyurethane tread provides grip and durability on warehouse floors, ramps, and dock levelers.
Q: What is the load capacity of the LJ 450-A roller?
A: The LJ 450-A is engineered with a service factor of 1.0, meaning it is rated for the maximum continuous load capacity of Lo-Jo model 5000 pallet jacks. Load ratings depend on jack configuration. Refer to your equipment manual for specific tonnage limits.
Q: How do the sealed ball bearings affect LJ 450-A durability?
A: Integrated sealed ball bearings eliminate external maintenance and contamination ingress. Seals are factory-lubricated and do not require field greasing. This design extends roller life in wet, dusty, and cold storage environments.
Q: Can I use the LJ 450-A on Lo-Jo models other than model 5000?
A: The LJ 450-A is specified for Lo-Jo model 5000 only. Do not attempt installation on other Lo-Jo models or non-Lo-Jo equipment without dimensional and load verification. Contact us to confirm fitment for alternative applications.
Q: What conditions cause LJ 450-A roller wear or failure?
A: Polyurethane tread wears faster on rough concrete, sharp edges, or over-loaded conditions. Bearing failure results from impact loads, extreme cold, or inadequate floor clearance. Flat spots indicate overload or improper storage. Replace when tread thickness drops below 1/8 inch or bearings show grinding noise.
