Frequently Asked Questions
Q: What is the AC 4907181 bearing used for?
A: The AC 4907181 is a rolling element bearing designed for manual pallet jack wheel assemblies and load wheel applications. It reduces friction between rotating shafts and stationary equipment frames, enabling smooth wheel operation under load.
Q: What are the bore diameter and load rating of AC 4907181?
A: The AC 4907181 has specific bore and outer diameter dimensions engineered for manual pallet jack compatibility. Dynamic load ratings vary by bearing type. Verify your equipment model and wheel shaft specifications match before ordering.
Q: What type of bearing is AC 4907181 and what material is it made from?
A: The AC 4907181 is typically a deep groove ball bearing or tapered roller bearing manufactured from hardened steel races with steel balls or rollers. The design provides reliable load support and resistance to radial and axial forces in pallet jack wheel systems.
Q: How do I know when the AC 4907181 bearing needs replacement?
A: Signs of bearing failure include rough wheel rotation, grinding noise from the wheel, increased friction, or wobbling wheel movement. Excessive heat or visible grease leakage indicate the bearing seal is damaged. Replace the bearing immediately to prevent wheel lock-up.
Q: How long does the AC 4907181 bearing last?
A: Bearings last 3-7 years in typical manual pallet jack use, depending on load, frequency, and maintenance. Warehouse use with frequent loads causes faster wear. Regular lubrication extends bearing life. Replace if internal clearance becomes excessive or the bearing no longer rotates freely.
Q: Are there cross-reference bearings from other pallet jack manufacturers?
A: The AC 4907181 is specific to Alice Chalmers manual pallet jacks. Crown, Toyota, Yale, and other manufacturers use different bearing specifications and sizes. Confirm your equipment model and wheel shaft diameter before ordering alternative bearings.
