Product Overview: The 392/3920 Tapered Roller Bearing
The 392/3920 is a single-row Inch Tapered Roller Bearing designed for exceptional performance in demanding applications. This bearing consists of two main separable parts: the inner ring with rollers and cage assembly (cone, part number 392) and the outer ring (cup, part number 3920). With a bore diameter of 44.45mm, an outer diameter of 77.788mm, and a total width of 20.638mm, this bearing is engineered to accommodate heavy combined radial and axial loads in one direction. Its tapered geometry ensures true rolling motion, minimizing friction and heat generation during operation.
As a key component in our extensive lineup of Tapered Roller Bearings, the 392/3920 is manufactured from high-quality bearing steel to ensure durability and longevity. The separable design simplifies mounting and dismounting procedures, making it a practical choice for a wide range of industrial and automotive machinery where reliability and precise load management are critical.
Key Features of the 392/3920 Bearing
- Single-Row Tapered Design: Optimized to handle significant radial and single-direction axial (thrust) loads simultaneously.
- Separable Components: The cone (inner ring assembly) and cup (outer ring) can be mounted independently, facilitating easier installation, inspection, and maintenance.
- High Load Capacity: The geometry of the tapered rollers and raceways provides a large contact area, enabling high load-carrying capabilities.
- Low Friction Operation: Precision engineering ensures true rolling motion, which reduces operational friction, minimizes wear, and extends the bearing's service life.
- Durable Construction: Manufactured from high-grade, case-hardened bearing steel for superior strength and resistance to wear and fatigue.
- Inch Series Standard: Designed to standard inch dimensions, ensuring interchangeability and suitability for a wide array of equipment built to these specifications.
