CUP, BEARING
Frequently Asked Questions
Q: What is the 20H3840 bearing cup used for?
A: The 20H3840 is a bearing cup component used in manual pallet jack load wheel bearing assemblies. It pairs with a matching bearing cone to form the complete bearing assembly that supports and rotates the load wheel under full load.
Q: Which pallet jack models use the 20H3840 bearing cup?
A: The 20H3840 bearing cup is compatible with manual pallet jacks from standard OEM manufacturers including Crown, Toyota, Raymond, Yale, and Clark. Verify your equipment model and wheel bearing dimensions before ordering to confirm compatibility.
Q: Can the 20H3840 bearing cup be used alone or does it require a matching cone?
A: The 20H3840 bearing cup must be paired with a matching bearing cone component (such as 209MDN1) to create a functional bearing assembly. The cup and cone work together to support and guide the rolling elements. Always order the complete matched bearing set for proper fitment.
Q: What material and finish does the 20H3840 bearing cup have?
A: The 20H3840 is constructed from case-hardened bearing steel with machined raceways designed to minimize friction and wear. The case-hardened steel provides high compressive strength to handle repeated loading cycles in warehouse environments.
Q: How do you identify when the 20H3840 bearing cup needs replacement?
A: Replace the 20H3840 bearing cup if the load wheel exhibits grinding noise, rough rotation, binding, or visible play in the axle. Visible wear, spalling, or denting in the bearing raceway surface also indicate replacement need. Bearing cups cannot be serviced; replacement of the complete cone and cup assembly is required.
