Frequently Asked Questions
Q: What is the HY 3003274 bearing cone used for?
A: The HY 3003274 is a bearing cone (inner race) for Hyster manual pallet jacks. This component is part of the tapered roller bearing assembly used in the load wheels or mast guide rollers. The cone works with the cup (outer race) to support radial and thrust loads during normal pallet jack operation.
Q: Which Hyster manual pallet jack models are compatible with the HY 3003274?
A: The HY 3003274 bearing cone is used in Hyster manual pallet jack models with tapered roller bearing assemblies. Verify exact compatibility by comparing bearing bore diameter, outer race diameter, and width. Check your jacks model and serial range against the original specification sheet to confirm fitment.
Q: What are the dimensions of the HY 3003274 bearing cone?
A: The HY 3003274 bearing cone dimensions include the bore diameter, cone width, and back face diameter. Exact measurements must be confirmed from the original equipment documentation or measured directly from your disassembled jack. Ordering the correct cone requires precise dimensional match to the mating cup.
Q: Can the HY 3003274 bearing cone be replaced separately or must the entire bearing assembly be replaced?
A: The HY 3003274 cone can be replaced as a separate component if the matching cup (outer race) is not damaged. However, if either the cone or cup shows spalling, wear, or discoloration, replace both components together. Mixing worn and new bearing races causes premature failure and uneven load distribution.
Q: What material is the HY 3003274 bearing cone made from?
A: The HY 3003274 bearing cone is manufactured from hardened alloy steel with a polished raceway surface. The hardness prevents deformation under the concentrated contact stresses from the roller balls or rollers. This material composition ensures durability in manual pallet jack applications with typical 2500 to 5000 pound load capacities.
