Single-Row Imperial Tapered Roller Bearing: TIMKEN-3780/3720
The product in the image is a Single-Row Imperial Tapered Roller Bearing: TIMKEN-3780/3720 (commonly associated with SET123 assemblies). It serves as an essential replacement component for heavy-duty truck wheels, automotive differentials, transmission setups, agricultural equipment, and industrial gear drives. It is manufactured using premium case-hardened alloy steel by The Timken Company, USA.
🔍 Technical Specifications
- Model Number: TIMKEN-3780/3720
- Cone Part Number (Inner Ring): 3780
- Cup Part Number (Outer Ring): 3720
- Bearing Type: Single-Row Tapered Roller Bearing (Imperial / Inch Series)
- Bore Diameter (Inner d): 2.0000 in (50.800 mm)
- Outer Diameter (D): 3.6718 in (93.264 mm)
- Total Bearing Width (T): 1.1875 in (30.163 mm)
- Cone Width (B): 1.1930 in (30.302 mm)
- Cup Width (C): 0.9375 in (23.813 mm)
- Basic Dynamic Radial Load Rating (\(C_{r}\)): 122,000 N (122.00 kN)
- Basic Static Radial Load Rating (\(C_{0r}\)): 153,000 N (153.00 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.
