Frequently Asked Questions
Q: What is the 00591-30273-81 bearing cone used for?
A: The 00591-30273-81 is a bearing cone component, the inner race of a tapered bearing assembly. The cone mounts onto the equipment shaft or axle and works with the bearing cup (outer race) and rolling elements to support loads and enable smooth rotation in pallet jack wheel or structural assemblies.
Q: What equipment does the 00591-30273-81 bearing cone fit?
A: The 00591-30273-81 is designed for Toyota manual pallet jack applications, including load wheel and pivot bearing systems. Verify the cone bore (shaft fit diameter) matches your equipment specifications. Use your equipment documentation or check the mating shaft diameter to confirm compatibility before installation.
Q: Should the 00591-30273-81 cone be replaced with the cup?
A: Yes. Best practice is to replace the 00591-30273-81 cone and the 00591-30263-81 cup as a matched pair. Even if only one component shows visible wear, replacing both ensures proper bearing preload, fit, and uniform load distribution. Using mismatched old and new components can result in premature failure.
Q: How do I install the 00591-30273-81 bearing cone?
A: The 00591-30273-81 cone is pressed onto the equipment shaft. Clean the shaft thoroughly and inspect it for damage or corrosion. Use a bearing press or drift tool to apply even pressure around the cone bore. Press until the cone seats squarely against the shaft shoulder. Do not force the cone; if resistance is high, verify shaft diameter and straightness.
Q: What material is the 00591-30273-81 bearing cone made from?
A: The 00591-30273-81 is manufactured from bearing-grade steel, hardened and heat-treated for wear resistance and load capacity. The steel construction provides durability under the dynamic loads encountered in manual pallet jack applications where the cone rotates continuously on the shaft.
Q: How do I remove a worn 00591-30273-81 bearing cone?
A: Use a bearing puller or cone removal tool to extract the 00591-30273-81 from the shaft. Place the puller jaws under the cone flange and apply steady tension. Do not strike the cone with a hammer. Once removed, inspect the shaft for wear marks, scoring, or corrosion. Clean the shaft before installing a new cone.
