Single-Row Imperial Tapered Roller Bearing: TIMKEN-25590/25520
The product in the image is a Single-Row Imperial Tapered Roller Bearing: TIMKEN-25590/25520 (commonly distributed as a SET54 assembly). It serves as an essential replacement component for automotive front axles, differential carriers, heavy-duty truck wheels, and industrial gear drives. It is manufactured using premium case-hardened alloy steel by The Timken Company, USA.
🔍 Technical Specifications
- Model Number: TIMKEN-25590/25520 (SET54)
- Cone Part Number (Inner Ring): 25590
- Cup Part Number (Outer Ring): 25520
- Bearing Type: Single-Row Tapered Roller Bearing (Imperial / Inch Series)
- Bore Diameter (Inner d): 1.7960 in (45.618 mm)
- Outer Diameter (D): 3.2650 in (82.931 mm)
- Total Bearing Width (T): 0.9375 in (23.812 mm)
- Cone Width (B): 1.0000 in (25.400 mm)
- Cup Width (C): 0.7500 in (19.050 mm)
- Basic Dynamic Radial Load Rating (\(C_{r}\)): 90,500 N (90.50 kN)
- Basic Static Radial Load Rating (\(C_{0r}\)): 111,000 N (111.00 kN)
⚙️ Design & Features
- Combined Heavy-Load Handling: Features precisely engineered conical raceways and tapered rollers. This layout supports substantial simultaneous radial forces and heavy unidirectional axial thrust loads.
- Separable Mechanical Architecture: The outer cup is completely independent from the inner cone-and-roller assembly. This design simplifies independent mounting, precision end-play adjustment, and cleaning routines.
- Stamped Steel Window Cage: Fitted with a robust, precision-stamped steel cage that evenly spaces the rolling elements to optimize uniform load balancing and limit internal friction. []
- Open System Setup: Constructed without integrated shields or contact seals to permit free-flowing grease lubrication or continuous high-efficiency hot oil immersion.
