Frequently Asked Questions
Q: What is the purpose of SKU 220023907 bearing cup in a manual pallet jack?
A: SKU 220023907 is a bearing cup component that creates the inner raceway for ball or roller bearings in manual pallet jack load wheels and steering assemblies. It sits inside the wheel hub and allows smooth, low-friction rotation of wheels under load. Proper cup fitment is critical for smooth jack operation.
Q: Which manual pallet jack models use SKU 220023907 bearing cup?
A: SKU 220023907 is compatible with manual pallet jacks from Crown, Toyota, Raymond, Hyster, and similar OEM manufacturers. Verify your jack model and wheel assembly specifications match this bearing cup dimensions and bore size before ordering. Incorrect cup size will cause poor wheel alignment or bearing failure.
Q: What material is SKU 220023907 made from and how durable is it?
A: This bearing cup is typically manufactured from hardened chrome steel or alloy steel to withstand repeated loading cycles and friction. Under normal warehouse use with proper bearing lubrication and maintenance, it should last 3 to 5 years or more. Harsh environments, salt spray, or inadequate lubrication reduce lifespan significantly.
Q: What symptoms indicate SKU 220023907 bearing cup needs replacement?
A: Common signs include grinding or squealing noises from wheels, rough steering feel, or visible lateral wheel wobble when rolling the jack. If you feel pitting or spalling on the cup inner surface during inspection, or if wheels no longer roll freely, the cup must be replaced immediately to prevent complete bearing failure.
Q: How does SKU 220023907 bearing cup compare to OEM equivalents?
A: This bearing cup meets or exceeds OEM specifications for hardness, dimensions, and load rating. Cross-reference numbers exist for Crown, Toyota, and Raymond equivalents. Verify bore diameter, width, and bearing type compatibility with your specific jack model to ensure correct fitment.
