Frequently Asked Questions
Q: What type of pallet jacks is the RA 447-580 bearing cup compatible with?
A: The RA 447-580 is an OEM wheel hub bearing cup designed for Raymond manual pallet jack assemblies featuring tapered roller bearing interfaces. It is not compatible with electric lift trucks.
Q: What is the material specification for the RA 447-580?
A: The RA 447-580 is manufactured from high-strength, heat-treated bearing-grade steel, typically SAE 52100 or equivalent. The precision-ground raceway surface is engineered to accept tapered roller bearings with minimal play.
Q: Are there alternate part numbers for the RA 447-580?
A: Alternate numbering conventions include RA 447580 and RA 447 580. All three refer to the same OEM part. When ordering, use the primary SKU RA 447-580 to ensure accuracy.
Q: What is the RA 447-580 used for in the pallet jack assembly?
A: This bearing cup serves as the outer race in the wheel hub assembly, providing precise bearing fitment and supporting both axial and radial load transfer. It is critical to wheel alignment and operational stability.
Q: What are the signs that an RA 447-580 needs replacement?
A: Replace the bearing cup if you observe excessive wheel play, grinding or squeaking noises during operation, visible spalling or pitting on the raceway, or difficulty steering. These indicate bearing wear or cup damage.
Q: How does surface finish affect the performance of the RA 447-580?
A: The precision-ground raceway finish ensures smooth rolling contact with tapered roller bearings, reducing friction and extending bearing life. Any contamination or damage to the ground surface compromises bearing performance.
