Product Details

The AP 0143500O is a precision-manufactured outer bearing cup (race) designed for L-44610 tapered roller bearing assemblies commonly used in RV, trailer, and light-duty axle applications. This cup forms the outer ring component of the bearing system and works in conjunction with the inner cone and roller assembly to support both radial and axial loads.

Key Features:

  • L-44610 specification tapered roller bearing cup
  • Precision-ground raceway surface for smooth operation and even load distribution
  • Constructed from high-grade bearing steel for durability and long service life
  • Press-fit design for secure installation in hub assemblies
  • Suitable for trailer hubs, RV axles, and light-duty automotive applications
  • Sold as individual outer cup component

Tapered roller bearings are the most widely used type of wheel bearing due to their ability to handle combined radial and thrust loads. The cup and cone should always be replaced together as a matched set to ensure optimal performance and maximize bearing life. This replacement cup is ideal for routine maintenance or when servicing trailer and RV wheel bearing assemblies.
