Frequently Asked Questions
Q: What pallet jack model does the DA 2748-4ZY78-001 fit?
A: This load roller assembly is designed for Dayton model 4ZJ78 pallet jacks. Confirm your equipment model matches 4ZJ78 before ordering, as different models require different assemblies.
Q: What materials are used in this load roller assembly?
A: The assembly features a polyurethane roller mounted on a steel hub with sealed ball bearings. This standard poly construction is suitable for general warehouse and material handling duties.
Q: Is the DA 2748-4ZY78-001 compatible with 4ZJ76 or 4ZJ77 models?
A: No. This assembly is designed for 4ZJ78 pallet jacks only. The 4ZJ76 requires DA 2748-4zy76-001 or DA 2748-4ZY76-002, and the 4ZJ77 requires DA 2748-4ZY77-001 or DA 2748-4zy77-002.
Q: How long will this standard poly load roller last?
A: Under normal warehouse conditions, expect 1 to 2 years of service life. Heavier loads and continuous daily use will reduce lifespan. Wet or abrasive floors also accelerate wear.
Q: What should I do if the roller rotates with difficulty or makes noise?
A: If the roller does not spin freely or produces grinding sounds, the bearings may be damaged. The sealed bearings cannot be serviced, so replace the entire assembly with a new DA 2748-4ZY78-001.
Q: Is there an ultra poly upgrade available for the 4ZJ78?
A: Based on current product data, an ultra poly version for the 4ZJ78 model is not listed. For improved durability, verify with our technical team if an upgrade option is available for your specific equipment configuration.
