HY 1507275

Frequently Asked Questions

Q: What is the HY 1507275 bearing cup and how does it function?
A: The HY 1507275 is the outer race of a tapered roller bearing assembly for Hyster electric pallet jacks. The bearing cup is the stationary component that works in conjunction with the bearing cone to provide load-carrying capacity. It is pressed into the equipment housing and supports rotating components under radial and thrust loads.

Q: Which Hyster pallet jack models use the HY 1507275 bearing cup?
A: The HY 1507275 is compatible with Hyster model W40Z or W45Z models with the B218 drive system designation. This bearing cup is designed for load wheel and mast support on these electric pallet jack models. Verify your complete equipment model and revision before placing an order.

Q: How should bearing cup and cone pairs be maintained?
A: The HY 1507275 bearing cup requires no direct maintenance; however, the bearing assembly housing must be kept lubricated per manufacturer specifications. Do not attempt to clean or relubricate the bearing cup directly. If the cup shows corrosion, pitting, or flaking, the entire bearing set must be replaced. Typical bearing cup life is 3 to 7 years with proper equipment maintenance.

Q: What is the proper way to order a replacement bearing cup?
A: Always order the HY 1507275 bearing cup as part of a complete bearing assembly replacement. This bearing cup must be paired with the corresponding HY 1507274 bearing cone. Order these components together to ensure proper fit and performance. Do not attempt to use the cup alone or with mismatched cones.
