Product Details

The National Oil Seal HM518445 is a premium tapered roller bearing cone assembly designed for heavy-duty automotive, truck, and industrial applications. This cone assembly consists of the inner ring, precision-ground rollers, and a stamped steel cage, engineered to handle both radial and thrust loads simultaneously.

Key Specifications:

  • Bore Diameter: 3.5 inches (88.9mm)
  • Cone Width: 1.5625 inches (39.688mm)
  • Material: Case-carburized chrome steel construction
  • Cage Type: Stamped steel for reliable roller retention
  • Series: HM518400

Features and Benefits:

  • Separable design allows independent installation of cone and cup components
  • Tapered geometry provides superior load distribution and reduced friction
  • High-quality steel construction resists fatigue and extends service life
  • Precision tolerances ensure proper alignment and smooth operation
  • Typically mounted in opposing pairs on shafts for optimal load handling

This bearing cone pairs with cup HM518410 (sold separately) to form complete bearing assembly SET415. Commonly used in wheel hubs, axles, and transmission applications where reliable performance under heavy loads is required. National Oil Seal bearings meet or exceed OEM specifications for quality and durability.

Autoplicity had great prices, excellent service, and the parts I ordered arrived quickly. I would highly recommend them and will definitely use them again.

Just recieved my order and the pit jug and spout were perfect. The shipping was very fast and it was by far the best price I could get on these products. Autoplicity is great.

Great customer service. My product came quickly and just as described. Can't beat the prices anywhere on the internet, I looked for 2 months before buying. Thanks!

VERY QUICK AND EASY

Very great service. I purchased a set of jba headers and hotchkin sway bar for my 2004, gto. I must say lowest pricing I found. Thanks!
