Frequently Asked Questions
Q: What is the 620915100 bearing cup and where is it used?
A: The 620915100 is a bearing cup component for electric lift truck load wheels. This cup seats in the outer race assembly of lift mast wheel systems on Crown, Toyota, Raymond, and similar electric pallet jacks. It is not a stand-alone bearing but a structural component.
Q: What is the material composition of the 620915100 bearing cup?
A: The 620915100 bearing cup is machined from hardened steel with precision tolerances for proper ball race seating. The surface finish is designed to minimize friction and support radial loads typical of powered material handling equipment.
Q: Is the 620915100 compatible with manual pallet jacks?
A: No. The 620915100 is designed specifically for electric lift truck mast assemblies, not manual equipment. Manual pallet jacks use different bearing cup dimensions and ratings. Verify equipment type before ordering.
Q: How do I determine if the 620915100 bearing cup needs replacement?
A: Replace the 620915100 if the load wheel exhibits lateral play when the lift is lowered, if you hear clicking during mast lowering, or if wheel alignment becomes inconsistent. A worn cup compromises load stability and increases brake wear.
Q: Can the 620915100 bearing cup be repaired or must it be replaced?
A: The 620915100 bearing cup cannot be resurfaced or repaired. Once worn or damaged, full replacement is required to restore load wheel precision and safe operation of the electric lift truck.
