CUP, BEARING
Frequently Asked Questions
Q: What is the LB-5004 bearing cup used for?
A: The LB-5004 is a bearing cup component that forms part of the load wheel assembly on manual pallet jacks. It provides the raceway surface for ball bearings in the wheel hub. This component is typically paired with LB-5004 bearing cone kits to create a complete bearing set.
Q: Which manual pallet jack models are compatible with the LB-5004 bearing cup?
A: The LB-5004 fits multiple manual pallet jack brands including Yale, Crown, Toyota, and Raymond models with compatible wheel hub assemblies. Verify hub bore size and width match the LB-5004 specifications before ordering. Incorrect bearing cup sizes cause wheel wobble and premature failure.
Q: What are the material and dimensional specifications of the LB-5004?
A: The LB-5004 bearing cup is manufactured from hardened steel for durability under repetitive load cycles. Specific bore diameter, outer diameter, and width dimensions match the wheel hub bore to ensure proper fit and load distribution. Contact us with your wheel hub specifications for exact dimensional confirmation.
Q: How long does the LB-5004 bearing cup typically last?
A: Properly maintained bearing cups last 5 to 10 years of regular use, depending on load intensity, floor conditions, and lubrication practices. High-load applications on rough floors reduce lifespan. Replace when visible pitting, spalling, or wear is observed on the raceway surface.
Q: What maintenance does the LB-5004 bearing cup require?
A: The bearing cup itself requires no direct maintenance once installed, but the complete bearing assembly requires periodic lubrication with wheel bearing grease. Inspect for contamination and water ingress regularly. Bearing cups cannot be cleaned or reused if damaged; replacement is necessary.
