Frequently Asked Questions

Q: What are the dimensions of the 00591-50722-81 bearing?
A: The 00591-50722-81 is a tapered roller bearing cone with a bore diameter of 1.5748 inches (40 mm) and an overall width of 1.455 inches (36.96 mm). These dimensions must match your pallet jack wheel bearing bore before ordering. Verify measurements against your equipment specifications to ensure proper fit.

Q: What load capacity does this cone bearing support?
A: The 00591-50722-81 has a dynamic load capacity of 38,700 lbs and a static load capacity of 46,200 lbs. Dynamic capacity is the load the bearing can handle during rotation; static capacity is for stationary loads. These ratings assume proper installation, lubrication, and a matched cup bearing. Overloading beyond these ratings will reduce bearing lifespan.

Q: Which Toyota pallet jacks use the 00591-50722-81?
A: The 00591-50722-81 is designed for Toyota manual pallet jack applications. The exact models that use this bearing depend on the jack series, generation, and load rating. Confirm compatibility by checking your equipment serial number and contacting us with the details. We can verify if this bearing is correct for your specific Toyota pallet jack.

Q: What is the construction type of this bearing?
A: The 00591-50722-81 is a single-row tapered roller bearing with a steel cage and steel rolling elements. Single-row construction provides radial and axial load capacity in a compact design suitable for manual pallet jack wheel assemblies. The steel cage reduces friction and improves load distribution compared to brass or polymer cages.

Q: What material is this bearing made from?
A: The 00591-50722-81 bearing cone is manufactured from hardened steel alloy. The rolling elements and cage are also steel. This all-steel construction provides durability, load capacity, and resistance to wear in heavy-duty manual pallet jack applications where loads are distributed repeatedly over the bearing.

Q: Do I need a matching cup bearing for this cone?
A: Yes. The 00591-50722-81 cone bearing must be installed with a matching cup bearing (outer race) to function as a complete tapered roller bearing set. The cup provides the outer raceway for the rolling elements. Contact us with your equipment details to identify the correct matching cup bearing part number.
