Frequently Asked Questions
Q: What is the 47412 bearing cup used for?
A: The 47412 bearing cup is a wear ring component used in manual pallet jack wheel assemblies. It seats bearing balls or rollers and distributes radial loads in the wheel hub assembly. This part is essential for smooth wheel rotation and load handling.
Q: Which manual pallet jack brands use the 47412 bearing cup?
A: The 47412 bearing cup is compatible with manual pallet jacks from Crown, Yale, Raymond, Hyster, Clark, and CAT. Fitment depends on wheel hub diameter and bearing configuration. Verify equipment model and serial range to confirm compatibility before ordering.
Q: What material is the 47412 bearing cup made from?
A: The 47412 bearing cup is manufactured from hardened steel with a chrome-plated or phosphate-coated finish. The raceway surface is precisely ground and hardened to Rockwell C48-54 hardness to resist wear from continuous ball or roller contact under manual pallet jack load cycles.
Q: How do I know if the 47412 bearing cup is worn out?
A: Inspect the bearing cup for visible pitting, spalling, or surface cracks in the raceway. Symptoms of wear include wheel wobble, noise during operation, increased friction when pushing the jack, or uneven wheel wear. Disassemble the wheel hub and examine the cup surface under direct light to assess damage.
Q: What is the expected service life of the 47412 bearing cup?
A: Under normal indoor warehouse conditions, the 47412 bearing cup typically lasts 4-7 years depending on load cycles and maintenance. Service life is extended by regular bearing lubrication, cleaning, and protection from wet or corrosive environments. Outdoor or high-frequency use may reduce service life to 2-3 years.
