Product Details

The Precision Parts 25580 is an industry-standard tapered roller bearing cone (inner ring assembly) designed to handle combined radial and thrust loads in a wide range of automotive, trailer, agricultural, and industrial applications. This single cone pairs with a compatible cup (outer ring), most commonly the 25520, 25521, 25522, 25523, or 25524 cup race, to form a complete single-row tapered roller bearing.

Key Specifications:

  • Part Number: 25580
  • Type: Tapered Roller Bearing Cone (Single Cone / Inner Ring)
  • Bore Diameter (ID): 1.750 in (44.45 mm)
  • Cone Width: 1.000 in (25.40 mm)
  • Cage Material: Stamped Steel
  • Bearing Material: 52100 Bearing-Grade Chrome Steel

  • Series: 25500

Features & Benefits:

  • Handles both radial and single-direction axial (thrust) loads simultaneously
  • Manufactured from high-grade chrome steel for strength and long service life
  • Heat-treated rolling elements for superior compressive load capacity and corrosion resistance
  • Stamped steel cage evenly spaces rollers to minimize friction, vibration, and noise
  • Engineered to meet or exceed OEM specifications for reliable fit and performance
  • Globally interchangeable inch-series design — compatible with most 6,000–10,000 lb trailer axles
  • Meets ASTM A295 standard

Common Applications:

  • Automotive and light truck wheel hubs
  • Trailer axle wheel ends (6,000–10,000 lb capacity axles)
  • Agricultural machinery axles and gearboxes
  • Industrial gearboxes and speed reducers
  • Heavy-duty construction and earthmoving equipment
  • Marine propeller shafts

The cone assembly is sold separately from the cup. For a complete bearing set, pair this cone with a compatible 25520-series cup race. Both components should be replaced together at service intervals to maximize bearing life and reliability.

The turbo (s475sx-e) has been my best purchase this year. The order was placed at the end of the workday and Thmotorsports shipped it the very next morning, also the box arrived in magnificent condition, the turbo was picture perfect without a blemish. Thmotorsports was the most affordable out of all ten sites that were considered, with top notch shipping. I have to say Thmotorsports was the best choice for my genuine part.

Ordered replacement seats for my fishing boat. I was shocked and impressed with the quality of the seats. They look as good as the originals from Tracker. Shipping was great, arrived sooner than I expected.

Great job

Good product

GREAT EXPERIENCE

Parts arrived in perfect condition. Installation went well. The on time and quick delivery was key to installation planning and

I thought I was getting 10% off my next order but never got that.
