98393/98788

The 98393/98788 is a high-precision imperial series tapered roller bearing, meticulously engineered to handle the rigorous demands of heavy-duty industrial environments. This specific assembly features a 3.9330-inch (99.898 mm) bore diameter (98393 cone) and a 7.8740-inch (200 mm) outer diameter (98788 cup), providing an optimized contact angle that excels at managing simultaneous radial and axial loads. Constructed from premium-grade carburized steel, the bearing offers superior fatigue resistance and durability. Its tapered geometry ensures that the rollers track accurately along the raceways, significantly reducing friction and heat generation during high-speed operations.

Designed for versatility and longevity, the 98393-98788 bearing is a staple in heavy machinery, including mining equipment, large-scale gearboxes, and automotive transmission systems. The separable design of the cone and cup allows for simplified mounting and maintenance, making it a preferred choice for engineers looking to minimize downtime. With a combined width of approximately 2.0772 inches, this single-row TS (Tapered Single) assembly is capable of maintaining precise shaft alignment under extreme pressure. Whether you are replacing an OEM part or designing a new drivetrain, this bearing provides the structural integrity needed for stable performance in high-torque applications.
