Frequently Asked Questions
Q: What is a bearing cone and how does it differ from a cup?
A: A bearing cone (SKU 3052179) is the inner raceway component that mounts on the shaft or axle. The cup is the outer raceway. Together they hold rolling elements under load. The cone rotates with the shaft while the cup remains stationary in the housing.
Q: Which manual pallet jack models use this bearing cone?
A: This bearing cone fits manual pallet jacks from Crown, Toyota, Raymond, Yale, and comparable OEM brands with matching bore diameter and width specifications. Verify your equipment model against the part number before ordering.
Q: Can this cone be replaced separately or must the entire bearing assembly be replaced?
A: This cone can be replaced separately if the matching cup remains serviceable. However, if the cone is worn, inspect the cup for corresponding damage. If both components show wear or spalling, replace the complete bearing set to avoid premature failure of the new cone.
Q: What material is this bearing cone made from?
A: Bearing cones are made from hardened steel with precision-ground raceways. The hardened steel resists wear from constant rolling contact with ball or roller elements under load typical in material handling equipment.
Q: What are signs this bearing cone needs replacement?
A: Grinding noise, rough operation, heat buildup, or visible spalling and pitting on the raceway surface indicate cone failure. Continued operation with a damaged cone damages the rolling elements and the cup raceway, requiring replacement of the entire bearing system.
