Frequently Asked Questions

Q: What is the 00591-00502-81 bearing cone used for?
A: The 00591-00502-81 is a Toyota OEM tapered roller bearing cone designed for manual pallet jack wheel and axle assemblies. It works in tandem with a matching bearing cup to support both axial and radial loads in industrial material handling applications.

Q: What material is the 00591-00502-81 bearing cone made from?
A: The 00591-00502-81 is manufactured from case-hardened bearing steel. This construction provides superior hardness and wear resistance required to handle the load cycles and friction inherent in pallet jack wheel assemblies.

Q: Do I need a matching bearing cup with the 00591-00502-81 cone?
A: Yes, the 00591-00502-81 cone is part of a tapered roller bearing assembly. It must be paired with the corresponding Toyota OEM bearing cup (such as 00591-00639-81 or 00591-00640-81) to form a complete wheel bearing. Do not install the cone alone.

Q: Which Toyota pallet jack models use the 00591-00502-81 bearing cone?
A: The 00591-00502-81 is designed for Toyota manual pallet jack wheel assemblies. Cross-reference your truck model and serial number with Toyota documentation to confirm this cone is the correct replacement for your specific equipment.

Q: How is the bearing cone installed and does it require special tools?
A: The bearing cone is typically pressed onto the wheel axle. Installation may require a bearing press or removal tool to avoid damage. Improper installation can cause premature bearing failure. If unfamiliar with the procedure, consult your equipment manual or contact us for guidance.

Q: What maintenance is required for the 00591-00502-81 bearing cone?
A: The bearing cone requires periodic greasing according to your pallet jack maintenance schedule. Clean the wheel assembly, pack the bearing cone with wheel bearing grease, and reinstall. Replace the bearing if excessive play, grinding, or scoring of the cone races is evident.
