Bearing Assembly

Frequently Asked Questions

Q: What are the specifications of the 5P5178 bearing assembly?
A: The 5P5178 is a bearing assembly for manual pallet jack load and steer wheel applications. For exact bore diameter, outer diameter, width, and load capacity, verify against your pallet jack documentation or contact us with your equipment model. Dimensional specs determine whether it fits your hub.

Q: What manual pallet jack models and brands is the 5P5178 compatible with?
A: The 5P5178 fits manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and other major material handling manufacturers. Confirm that the bore diameter matches your wheel hub and that the outer diameter and width clear your equipment frame. Verify fitment specifications with us before ordering.

Q: What materials and sealing design does the 5P5178 use?
A: The 5P5178 features hardened steel bearing races precision-ground for manual pallet jack duty cycles. Confirm whether your application uses sealed bearings with rubber shields or open designs. Contact us to identify the exact seal type and rubber compound suited to your floor environment.

Q: What cross-reference or equivalent part numbers exist for the 5P5178?
A: The 5P5178 is identified by this part number. If your pallet jack manual lists an OEM designation or you need to cross-check with other bearing suppliers, share that information and we can verify compatibility and confirm available equivalents.

Q: What is the maintenance and service life expectancy for the 5P5178?
A: Bearing life varies based on wheel load distribution, floor conditions, and lubrication frequency. Sealed bearings require monitoring and replacement when worn. Unsealed types need regular greasing or oil per your pallet jack service schedule. Inspect bearings if you notice increased wheel resistance or noise.
