Product Description
Bearing Cup for Manual Pallet Jack Wheel Assemblies
The bearing cup is a precision-engineered component designed for use in manual pallet jack wheel assemblies. It serves as the outer race of a tapered roller bearing set and works in tandem with a matching taper cone bearing to provide reliable load support and smooth wheel rotation. Manufactured from through-hardened steel for durability and long-term performance, this bearing cup is a direct replacement component for maintaining proper wheel function and equipment reliability in manual pallet jacks.

Frequently Asked Questions
Q: What is the 00591-50721-81 bearing cup used for?
A: The 00591-50721-81 is a bearing cup component designed for manual pallet jack wheel assemblies. It serves as the outer race of a tapered roller bearing set and must be paired with a matching taper cone bearing to support the wheel load.
Q: What equipment is compatible with the 00591-50721-81?
A: This bearing cup is compatible with manual pallet jacks that use this OEM specification. Verify compatibility by referencing your equipment model documentation or providing us with your pallet jack manufacturer and model number. We can confirm if this part is correct for your equipment.
Q: Is this cup part of a bearing set?
A: Yes. The 00591-50721-81 bearing cup is one half of a tapered roller bearing set. It must be installed with a matching taper cone bearing. The two components work together to provide load support and bearing functionality. Never install a cup without its matching cone bearing.
Q: What material is this bearing cup made from?
A: Bearing cups for manual pallet jack applications are manufactured from through-hardened steel, typically equivalent to SAE 52100 or similar high-carbon alloy. This material provides the hardness and durability needed to withstand radial and axial loads without premature wear or spalling.
Q: Can I order this cup separately or must I buy a bearing set?
A: The 00591-50721-81 cup is available as an individual component. However, for proper bearing function and load support, you also need the matching taper cone bearing. Contact us with your equipment details and we can confirm the correct cone bearing part number to pair with this cup.
