Frequently Asked Questions
Q: What manual pallet jack models does bearing assembly 4391154 fit?
A: This bearing assembly is used in manual pallet jacks from Crown, Toyota, Raymond, Yale, Hyster, and other OEM brands. Bearing assemblies often appear in the load wheel or swivel caster assembly. Verify your pallet jack model and serial range to confirm fit.
Q: What are the dimensions and bore size of this bearing assembly?
A: Bore diameter, outer diameter, and width must be verified against your equipment. Measure the existing bearing or consult your pallet jack service manual for exact specifications. Incorrect dimensions will result in poor fitment and load wheel failure.
Q: What load capacity is this bearing assembly rated for?
A: Load rating depends on the manual pallet jack capacity and bearing material specifications. Confirm your jack is rated for 2500, 3000, 4000, or 5000 pounds and match this bearing to that capacity. Undersized bearings fail under load.
Q: How long does this bearing assembly last before replacement?
A: Manual pallet jack bearing life depends on usage frequency, load cycles, and maintenance. Sealed bearings require minimal maintenance but should be inspected for noise or play. Replace if you hear grinding sounds or feel excess movement in the wheel.
Q: Is this bearing sealed or open, and does it require grease?
A: This is a sealed bearing assembly, meaning lubrication is pre-installed and the bearing is protected from contamination. Sealed bearings do not require field greasing. Do not attempt to add grease as this can cause seal failure and bearing damage.
