Frequently Asked Questions
Q: What is the difference between ultra poly and standard poly for the 4ZJ77?
A: Ultra poly (DA 2748-4zy77-002) offers greater wear resistance and longer service life compared to standard poly (DA 2748-4ZY77-001). Ultra poly is recommended for heavy daily use and challenging floor conditions.
Q: Which Dayton pallet jack model does the DA 2748-4zy77-002 fit?
A: This ultra poly load roller assembly is designed specifically for Dayton model 4ZJ77 pallet jacks. Verify your equipment model before ordering.
Q: Can I use this ultra poly assembly on my 4ZJ76 or 4ZJ78 pallet jack?
A: No. This assembly is machined for the 4ZJ77 model only. The 4ZJ76 requires DA 2748-4ZY76-002, and the 4ZJ78 requires DA 2748-4ZY78-001.
Q: How much longer does ultra poly last compared to standard poly?
A: In high-cycle environments, ultra poly can last 30 to 50 percent longer than standard poly. The actual lifespan depends on load weight, floor surface, and usage intensity.
Q: Is the bearing construction different in the ultra poly version?
A: No. Both standard and ultra poly versions for the 4ZJ77 have identical sealed steel hubs with ball bearings. The improvement is in the roller compound only.
Q: What environments benefit most from ultra poly on the 4ZJ77?
A: Ultra poly excels in cold storage, on wet floors, with heavy repetitive loads, and on abrasive or uneven concrete. If your 4ZJ77 operates in these conditions, ultra poly extends assembly life significantly.
