Frequently Asked Questions
Q: What manual pallet jack models use the 128478 bearing assembly?
A: The 128478 bearing assembly is designed for manual pallet jack load wheels and caster assemblies. Common compatible brands include Crown, Yale, and Raymond manual jacks. Confirm the part number and jack model against the equipment specification sheet to verify fitment.
Q: What are the load capacity and dimensions of bearing 128478?
A: The 128478 is a sealed bearing assembly rated for standard pallet jack duty, typically 2000 to 5500 pound load capacity depending on equipment design. Verify the bore size and outer diameter match your manual jack axle before ordering. Check your jack nameplate for load rating specifications.
Q: How long does a 128478 bearing assembly last on a manual pallet jack?
A: Under normal warehouse use, the 128478 bearing assembly typically operates 3000 to 8000 hours before replacement becomes necessary. Lifespan depends on load consistency, floor conditions, and maintenance. Rough floors and continuous heavy use reduce bearing life. Replace when noise or wheel drag is detected.
Q: What is the material type of the 128478 bearing assembly?
A: The 128478 is a sealed rolling bearing with hardened steel inner and outer races. Sealed contact shields protect against floor dust and contamination. The sealed design reduces maintenance requirements compared to open bearing designs.
