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 polyurethane tread, die-cast aluminum hub, and integrated sealed ball bearings designed for continuous industrial service.
Q: What are the material specifications?
A: The hub is A380 die-cast aluminum per ASTM B85 for strength and corrosion resistance. Hardware is carbon steel per SAE J403. The polyurethane tread provides grip and durability on warehouse floors, ramps, and dock levelers.
Q: What is the rated load capacity of this 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 sealed ball bearings improve durability?
A: Integrated sealed ball bearings eliminate external maintenance and prevent 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 this roller on other Lo-Jo models?
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 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 or bearings show grinding noise.
