Big Joe Polyurethane Load Wheel Assembly

Frequently Asked Questions

Q: What are the key specifications for the BJ 78237 load wheel?
A: The BJ 78237 features a polyurethane wheel hardness. It includes press-fit ball bearings and is corrosion resistant. The polyurethane construction and bearing system make it suitable for general warehouse and material handling operations.

Q: How does the compare to smaller load wheel sizes?
A: The provides a larger wheel radius than 2.75 inch alternatives, which results in smoother rolling over small obstacles and floor imperfections. This larger size reduces rolling resistance and requires less operator effort on rougher floors. The provides better load distribution compared to narrower wheels.

Q: What does mean for the BJ 78237 polyurethane wheel?
A: is a medium hardness rating measured on the Shore A scale (used for flexible materials like polyurethane). This hardness provides good traction on most warehouse floors while resisting premature wear. It offers a balance between grip and durability for standard indoor material handling without specialized floor conditions.

Q: Does the BJ 78237 wheel resist corrosion in humid environments?
A: Yes, the BJ 78237 is specified as corrosion resistant, making it suitable for humid warehouse environments and areas with occasional water exposure. The polyurethane material and corrosion-resistant bearings minimize rust formation on the wheel assembly. This feature extends component life in facilities with moisture challenges.

Q: What bearing type does the BJ 78237 use and how does it differ from other designs?
A: The BJ 78237 uses press-fit ball bearings, which are pressed directly into the wheel hub during manufacturing. This design creates a sealed, permanent assembly that requires no maintenance. Press-fit bearings are cost-effective and reliable for standard duty applications where bearing removal is not necessary during the wheel lifespan.
