Product Overview: The 2788/20 Tapered Roller Bearing
The 2788/20 is a single-row inch series Tapered Roller Bearing designed for exceptional performance in a wide range of industrial and automotive applications. With a bore diameter of 44.45mm, an outer diameter of 77.788mm, and a width of 18.258mm, this bearing is engineered to handle a combination of heavy radial and axial (thrust) loads in one direction. Its design consists of two separable main components: the inner ring with rollers and cage (cone assembly, part number 2788) and the outer ring (cup, part number 2720). This separability simplifies mounting, dismounting, and maintenance procedures.
The tapered geometry of the rollers and raceways creates a true rolling motion and ensures high load-carrying capacity. As a key component in machinery requiring robust rotational support, the 2788/20 bearing provides high stiffness and longevity. Our extensive collection of Inch Tapered Roller Bearings offers reliable solutions for your most demanding operational needs.
Key Features of the 2788/20 Bearing
- Combined Load Capacity: Expertly designed to manage both high radial and single-direction axial loads simultaneously.
- Separable Design: The cone (inner ring assembly) and cup (outer ring) are separable, facilitating easier installation, inspection, and maintenance.
- Low Friction Operation: The tapered design minimizes rolling friction, which reduces heat generation and allows for higher operational speeds.
- High Stiffness: Provides excellent shaft guidance and system rigidity, crucial for applications requiring precise alignment and stability.
- Durable Construction: Manufactured from high-quality, case-hardened bearing steel for superior wear resistance and extended service life.
- True Rolling Motion: The geometry ensures that the rollers and raceways interact at an angle, resulting in pure rolling and preventing slippage under load.
Common Applications
- Automotive Systems: Widely used in vehicle wheel hubs, transmissions, and differentials.
- Industrial Gearboxes: Provides reliable support for gears and shafts in heavy-duty reducers and transmissions.
- Agricultural Machinery: Essential for equipment such as tractors, harvesters, and tillage implements where heavy loads are common.
