Frequently Asked Questions
Q: What is SKU 55558700 and what does it do?
A: SKU 55558700 is a bearing cone component used in wheel hub assemblies for manual pallet jacks. It is part of a ball bearing system that supports load wheel rotation.
Q: Which manual pallet jack brands use this bearing cone?
A: This bearing cone is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and other OEM manufacturers. Verify your wheel hub dimensions before ordering.
Q: What material is this bearing cone made from?
A: This bearing cone is typically made from hardened steel with a minimum Rockwell hardness specification for durability under repeated load cycles in material handling applications.
Q: When should I replace a bearing cone?
A: Replace the bearing cone when you notice wheel resistance, grinding sounds, or irregular rotation. Inspect during routine maintenance. Worn cones require replacement of the entire bearing assembly for optimal performance.
Q: Do I need to replace the cup at the same time as the cone?
A: Yes. The cone and cup are matched components in a bearing assembly. Replace both together to ensure proper fit, smooth rotation, and load capacity. Mixing old and new components can cause premature failure.
