Frequently Asked Questions
Q: What Hyster models does the HY 78584 tapered bearing cone fit?
A: The HY 78584 is a tapered bearing cone designed for Hyster W40XL and W40XT electric walkie pallet trucks. It functions in the drive unit and brake assembly components. Verify your equipment model and serial range before ordering to ensure compatibility.
Q: What are the OEM alternative part numbers for the HY 78584?
A: The HY 78584 has recognized alternative designations including HY78584, 0078584, 78584, and SK16180207JE. These references refer to the same tapered bearing cone component. Cross-referencing with your original equipment documentation is recommended for order accuracy.
Q: Where is the HY 78584 bearing cone installed in a Hyster electric pallet jack?
A: The HY 78584 tapered bearing cone is installed in the drive unit and brake assembly of Hyster W40XL/W40XT electric walkie pallet trucks. These components are critical for proper drive shaft rotation and brake function. The bearing cone works with a matching race to support load and reduce friction.
Q: What is a tapered bearing cone and why is it used in pallet jacks?
A: A tapered bearing cone is a rolling element bearing component that supports radial and axial loads at angles. In pallet jacks, tapered bearings are used in drive units and brake assemblies because they can handle both rotating shaft loads and thrust forces efficiently. The cone design provides high load capacity in a compact space.
Q: How do I verify that HY 78584 is the correct bearing cone for my equipment?
A: Check your Hyster W40XL or W40XT technical documentation or parts diagram for bearing specifications. Cross-reference your equipment serial number and the bearing assembly location (drive unit or brake assembly). Confirm the tapered cone dimensions match your replacement requirement before ordering.
