BJ 78673

Frequently Asked Questions

Q: What are the key specifications of the BJ 78673 load wheel?
A: The BJ 78673 is a polyurethane-on-steel load wheel assembly with a 3.25 inch diameter and 4.36 inch width. It features sealed deep groove ball bearings, high carbon steel core, and is rated for 2000 lbs static load. The polyurethane tread has 95 Shore A hardness for durability on concrete floors.

Q: Which Big Joe models use the BJ 78673?
A: The BJ 78673 is engineered for Big Joe electric pallet jacks. Confirm your equipment model and serial range match this part number before ordering. The 3.25 inch diameter and 4.36 inch width dimensions must match your jack configuration.

Q: What bearing type does the BJ 78673 use?
A: The BJ 78673 uses sealed deep groove ball bearings manufactured from chrome steel SAE 52100. The sealed design protects bearings from dust, moisture, and contaminants, extending service life in warehouse environments.

Q: What is the load rating for the BJ 78673?
A: The BJ 78673 is rated for 2000 lbs static load. This rating applies when the wheel is properly installed and load is evenly distributed across all wheels on the jack. Exceeding this rating may cause bearing failure or structural damage.

Q: How durable is the 95 Shore A polyurethane tread on the BJ 78673?
A: 95 Shore A polyurethane is mid-range hardness suitable for general warehouse floors. It resists abrasion and provides good floor grip on dry concrete. On wet floors or in cold storage, traction may be compromised. Wheels typically last 2 to 5 years depending on usage frequency and floor conditions.

Q: Can the BJ 78673 be used on wet or oily floors?
A: Standard 95 Shore A polyurethane provides reduced traction on wet, slippery, or oily floors. For wet floor or cold storage applications, we offer high-traction polyurethane alternatives with EZ formulation that deliver better grip in challenging conditions.
