Frequently Asked Questions
Q: What manual pallet jack models does the SY40784 bearing cup fit?
A: The SY40784 bearing cup is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, and Hyster. The cup is used in load wheel hub assemblies. Verify your pallet jack model and wheel bore diameter to confirm fitment before ordering.
Q: Is the SY40784 a tapered or deep-groove bearing cup?
A: The SY40784 is a tapered roller bearing cup (outer race) typically used in manual pallet jack load wheel hubs. Tapered roller bearings provide high load capacity and axial stiffness for manual truck wheel applications. The cup must be installed with a matching tapered cone and rollers.
Q: What material and precision standard is the SY40784?
A: The SY40784 is manufactured from high-carbon hardened steel ground to precision bearing tolerances. The material and finish are engineered to resist corrosion and wear in manual material handling environments including damp warehouse floors.
Q: Can I replace just the SY40784 cup or do I need a complete bearing kit?
A: If only the outer race (cup) is damaged and your inner race (cone) and rollers are in good condition, the SY40784 cup alone may be installed. However, bearing cups and cones are wear pairs. If the cone shows pitting or wear, replace the complete bearing assembly for best results.
Q: What cross-reference part numbers match the SY40784?
A: The SY40784 is equivalent to bearing cup assemblies listed in Crown, Toyota, and Raymond manual pallet jack maintenance documentation. Provide your pallet jack model and year and we can supply OEM cross-reference numbers and recommend whether a complete bearing kit or cup-only replacement is appropriate.
