Product Overview: The 3984/20 Tapered Roller Bearing
The 3984/20 is a high-performance, single-row Inch Tapered Roller Bearing designed for heavy-duty applications. This bearing is an assembly consisting of the 3984 cone (inner ring, rollers, and cage) and the 3920 cup (outer ring). With a bore diameter of 53.975 mm, an outer diameter of 96.838 mm, and a total width of 21.438 mm, it is engineered to handle substantial combined radial and axial loads in one direction. Its tapered design ensures smooth, low-friction operation, making it a reliable choice for demanding industrial and automotive environments.
As a key component in our Tapered Roller Bearings collection, the 3984/20's separable components simplify mounting, dismounting, and maintenance procedures. These bearings are typically mounted in opposing pairs to accommodate axial loads in both directions, providing robust and precise rotational support for shafts and housings. Trust our high-quality bearings for superior performance and longevity in your machinery.
Key Features of the 3984/20 Bearing
- Separable Design: The cone (3984) and cup (3920) are separable, allowing for easier installation, removal, and inspection.
- High Load Capacity: Engineered to support heavy radial and axial (thrust) loads in a single direction.
- Low-Friction Operation: The tapered geometry of the rollers and raceways minimizes rotational friction and heat generation.
- Durable Construction: Manufactured from high-quality bearing steel for exceptional durability, wear resistance, and long service life under harsh conditions.
- Axial Load Management: Can be mounted in pairs (e.g., back-to-back or face-to-face) to handle axial loads from both directions.
- Precise Roller Guidance: The flange on the inner ring guides the rollers, ensuring true rolling motion and stability.
Common Applications
- Automotive Systems: Widely used in vehicle wheel hubs, transmissions, and differentials.
- Industrial Gearboxes: Provides essential support for gears and shafts in heavy-duty industrial reducers.
- Agricultural Machinery: Ideal for use in tractors, harvesters, and other farm equipment axles and transmissions.
