Frequently Asked Questions
Q: What is the material composition of the DA 2748-4ZY78-002 load roller assembly?
A: The DA 2748-4ZY78-002 features an ultra polyurethane roller mounted on a steel hub with sealed ball bearings. Ultra poly provides enhanced traction and durability compared to standard polyurethane, making it suitable for demanding material handling applications and wet floor environments.
Q: Which pallet jack models does the DA 2748-4ZY78-002 fit?
A: The DA 2748-4ZY78-002 is designed specifically for Dayton model 4ZJ78 pallet jacks. Verify your equipment model number before ordering to ensure proper fitment.
Q: What is the typical lifespan of this load roller assembly?
A: Load roller lifespan depends on usage intensity and floor conditions. Ultra poly rollers typically outlast standard poly by 30-50% in heavy-use environments. Regular inspection for wear, flat spots, or bearing play helps identify when replacement is needed.
Q: Does the DA 2748-4ZY78-002 come with sealed bearings?
A: Yes, the DA 2748-4ZY78-002 includes sealed ball bearings in the steel hub. Sealed bearings reduce maintenance requirements and protect against contamination from dust and moisture.
Q: Can the DA 2748-4ZY78-002 be used in cold storage applications?
A: Yes, ultra polyurethane material remains flexible and grippy in cold storage environments, making the DA 2748-4ZY78-002 suitable for refrigerated warehouse applications where standard poly becomes brittle.
