Frequently Asked Questions
Q: What is the bearing cone 00591-55085-81 used for on manual pallet jacks?
A: This bearing cone is part of the tapered roller bearing set in manual pallet jack load wheels. It works with the outer race to support the wheel under load. This cone component is compatible with most standard manual pump trucks from common OEM brands.
Q: Does this bearing cone come as a complete assembly or single component?
A: The 00591-55085-81 is the cone portion only of a tapered bearing set. Replacement typically requires purchasing both the cone and cup (outer race) as matched pairs to maintain proper bearing clearance and performance.
Q: What material is this bearing cone made from?
A: The bearing cone is hardened steel with tapered rolling surfaces designed to handle radial and axial loads. The heat-treated steel resists wear from friction with the matching cup under heavy wheel loads.
Q: What dimension should I verify before ordering this bearing cone?
A: Confirm the bore diameter and overall width of your existing bearing set. The cone must match the wheel hub bore size precisely. Mismatched bearing cones and cups cause binding, noise, and premature failure.
Q: How long does a bearing cone typically last on a manual pallet jack?
A: Bearing lifespan depends on load, surface conditions, and maintenance. Regular greasing keeps the bearing running smoothly. Replace the cone and cup together when you hear grinding noise or feel resistance in wheel rotation.
Q: Can this bearing cone be lubricated or must it be replaced?
A: Tapered bearing cones in manual pallet jacks require periodic greasing. If a cone is damaged, pitted, or shows spalling, replace it with a matched cup as a set. Attempting to repair a damaged cone reduces bearing life and wheel safety.
