Product Details

The Federal Mogul (National) 39521 is a premium tapered roller bearing cup (outer ring) engineered for John Deere and farm implement front wheel (FW) and rear wheel (RW) applications. As the outer ring of a tapered roller bearing assembly, this cup pairs with a separately available cone (inner ring assembly) to form a complete, fully functional tapered roller bearing.

Key Features:

  • Premium-Grade Steel Construction: Manufactured from high-quality steel for superior durability and long service life in demanding agricultural environments
  • Crowned Raceways: Engineered with crowned raceways to ensure even load distribution across the bearing surface, reducing stress concentrations and wear
  • Handles Combined Loads: Tapered roller design absorbs both radial and axial (thrust) forces simultaneously, ideal for wheel-end applications
  • OE Specification Compliance: Engineered to meet or exceed original equipment specifications for reliable, drop-in replacement performance
  • Separable Design: Cup and cone are separable for easy installation; end play or preload can be adjusted axially during assembly
  • Quantity: Sold individually (2 per application required)

Dimensions: Outer Diameter (D): 4.4375 in (112.713 mm) | Width (W): 0.9375 in (23.8125 mm)

The National® brand, part of Federal-Mogul Motorparts, has delivered premium wheel-end solutions for over 60 years. The 39521 bearing cup is a trusted replacement part for maintaining smooth, reliable operation on John Deere tractors and a wide range of farm implement wheel-end assemblies.
