Frequently Asked Questions
Q: What is a bearing cup and what does part 31-48513 do?
A: A bearing cup is the outer raceway component of a tapered roller bearing or ball bearing assembly. Part 31-48513 is the cup assembly that works with a corresponding bearing cone to form a complete bearing unit in pallet jack wheel hubs.
Q: Which pallet jack equipment types use bearing cup 31-48513?
A: Bearing cup 31-48513 is compatible with manual pallet jacks and electric lift trucks from Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, and other major manufacturers. Confirm bore size and load wheel specifications match your equipment before ordering.
Q: What material is bearing cup 31-48513 made from?
A: The bearing cup is manufactured from hardened bearing steel with precision-ground raceways. This material provides the strength and wear resistance needed for material handling applications with repeated load cycles.
Q: How do I know if the bearing cup needs replacement?
A: Replace the bearing cup if you hear grinding, rumbling, or squeaking from the wheel hub, if the wheel has excessive play or wobbles, or if you observe visible scoring or spalling on the raceway surface. A worn bearing cup reduces wheel performance and increases safety risks.
Q: What is the OEM part number for this bearing cup?
A: The OEM part number is 31-48513. This is the standard reference for this bearing cup assembly across compatible pallet jack models.
Q: Does bearing cup 31-48513 require a matching cone or bearing element?
A: Yes. The bearing cup works as part of a complete bearing assembly. Verify you have the correct matching bearing cone or ball bearing set for your equipment before ordering the cup alone.
