AP SC-4110

Frequently Asked Questions

Q: What is the AP SC-4110 bearing cup designed for?
A: The AP SC-4110 is a bearing cup for electric lift trucks and electric pallet jacks. It is the outer race component of a tapered roller bearing assembly, used in load wheel and drive wheel applications to support axle shafts and distribute loads.

Q: What are the material properties of the AP SC-4110 bearing cup?
A: The AP SC-4110 is manufactured from case-hardened steel with precision ground and honed raceways. Case-hardening provides a tough outer surface while maintaining a softer core, creating durability for high-load applications in electric lift equipment. The precision ground raceways ensure smooth rolling and minimal friction.

Q: How is the AP SC-4110 bearing cup mounted to the equipment?
A: The AP SC-4110 uses press-fit mounting, meaning it is pressed into a bore in the wheel hub or axle housing. Press-fit mounting ensures the cup remains firmly in place and maintains proper alignment under load and vibration.

Q: What electric lift truck models use the AP SC-4110 bearing cup?
A: The AP SC-4110 is compatible with standard draw cup bearing assemblies used across multiple electric pallet truck manufacturers including Crown, Toyota, Raymond, Hyster, and Linde. Verify your original OEM part number is SC-4110 to confirm compatibility.

Q: Is the AP SC-4110 a direct replacement for the OEM SC-4110?
A: Yes, the AP SC-4110 directly replaces OEM SC-4110 bearing cups. It meets the same dimensional and material specifications as the original equipment component.

Q: How long does the AP SC-4110 bearing cup last in service?
A: Bearing cup lifespan depends on load weight, duty cycle, and lubrication maintenance. Under typical electric lift truck operating conditions, a quality bearing cup can last 3 to 5 years. High-intensity use or inadequate lubrication reduces service life.
