CT 972370

Frequently Asked Questions

Q: What pallet jack model is the CT 972370 bearing cup designed for?
A: The CT 972370 bearing cup is compatible with CAT Caterpillar model 6600 manual pallet jacks. Verify your pallet jack model number before ordering to ensure correct fitment.

Q: What is the role of a bearing cup in a pallet jack?
A: The bearing cup provides the outer raceway surface for rolling elements in the load wheel or pivot assembly. It works with a mating bearing cone to support radial loads and enable smooth pallet jack operation.

Q: What material makes up this bearing cup?
A: Bearing cups are manufactured from hardened alloy steel with a precision-finished raceway surface. This material provides wear resistance and maintains bearing preload and alignment throughout the pallet jack operating life.

Q: Can the CT 972370 be interchanged with bearing cups from other Caterpillar pallet jack models?
A: The CT 972370 is specifically engineered for the model 6600 pallet jack. Do not interchange bearing cups between different models as dimensional and load rating differences can result in improper fit and equipment failure.

Q: What visible damage requires immediate bearing cup replacement?
A: Replace the bearing cup if the raceway surface shows pitting, spalling, deep scratches, corrosion, or visible cracks. Any damage to the raceway surface causes uneven load distribution, vibration, and rapid bearing wear.

Q: How does lubrication affect bearing cup performance?
A: Proper lubrication reduces friction between rolling elements and the raceway, minimizes heat generation, and extends bearing life. Insufficient or contaminated lubricant accelerates wear on the bearing cup raceway surface and shortens component lifespan significantly.
