Frequently Asked Questions
Q: What is the difference between the SY47422 and SY47412 bearing cups?
A: The SY47422 and SY47412 are bearing cups designed for different wheel assembly applications. Although both are hardened steel cups, they fit different load wheel sizes or axle diameters. Confirm your equipment load wheel configuration to determine which cup you need.
Q: What manual pallet jack brands use the SY47422 bearing cup?
A: The SY47422 bearing cup is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, Mitsubishi, and Clark. Verify compatibility with your specific model, as different series within a brand may use different bearing cup configurations.
Q: How do dimensions affect bearing cup selection for the SY47422?
A: Bearing cup selection is based on internal diameter, outer diameter, and cup depth, which must match your equipment wheel bearing bore and axle specifications. The SY47422 is precision-manufactured to exact dimensions. Measure your existing cup or consult equipment documentation before ordering.
Q: What maintenance does the SY47422 bearing cup require?
A: The SY47422 bearing cup itself requires no routine maintenance beyond regular inspection for damage or wear. However, the ball or roller bearings that ride in the cup should be cleaned and regreased annually or per your equipment manufacturer recommendations to prevent cup and bearing deterioration.
Q: Can the SY47422 bearing cup be repaired or must it be replaced?
A: The SY47422 bearing cup is a non-serviceable consumable part. Once worn, scored, or damaged, it must be replaced. Attempting to repair a damaged cup will result in uneven bearing contact, premature bearing failure, and potential loss of load control.
