Frequently Asked Questions

Q: What is SKU 3052980 used for?
A: SKU 3052980 is a bearing cup component designed for electric lift truck mast and wheel bearing assemblies. It forms the stationary outer race of the bearing assembly, supporting radial and thrust loads in vertical lift and horizontal travel operations.

Q: Which electric lift truck applications use this bearing cup?
A: This bearing cup is used in load wheel bearings and mast roller assemblies of electric lift trucks from Crown, Toyota, Raymond, Yale, Linde, Hyster, and Jungheinrich. Confirm the cup bore diameter and height match your equipment specifications before ordering.

Q: What material is this bearing cup made from?
A: This bearing cup is manufactured from hardened alloy steel or carbon steel precision-ground to tight tolerances. The material provides wear resistance and dimensional stability required for sustained rotational loading in material handling equipment.

Q: Where is this bearing cup located in the lift truck assembly?
A: This bearing cup serves as the outer race in either the load wheel assembly or mast roller bearing assembly, depending on the specific lift truck model. The cup maintains fixed position while inner bearing balls rotate against it during mast movement and wheel operation.

Q: What is the typical lifespan of this bearing cup?
A: Bearing cup lifespan depends on equipment usage intensity, lubrication maintenance, and load consistency. Expect 4 to 8 years of normal warehouse operation. Replace when you observe increased friction, audible grinding, or visible surface damage on the bearing raceway.
