The Timken Company 93751D 90113 Tapered Roller Bearing

Description:

The Timken 93751D/90113 tapered roller bearing is a heavy-duty TDI (Tapered Double Inner) bearing assembly featuring a double cone paired with matched outer cups. Engineered to support extremely high combined radial and axial loads, this bearing provides exceptional rigidity, accurate shaft positioning, and long service life in demanding industrial environments. It is commonly installed in rolling mills, mining equipment, steel processing machinery, large industrial gearboxes, and heavy power transmission systems. Maintenance teams, OEMs, and system integrators use this bearing assembly for equipment repairs, bearing replacements, retrofit projects, and preventive maintenance to maximize equipment reliability and reduce unplanned downtime.

Applications:

The Timken 93751D/90113 TDI bearing assembly is designed for severe-duty industrial applications requiring high load capacity and precise shaft alignment. Its double-cone configuration delivers increased rigidity and improved axial load distribution, making it ideal for rolling mills, mining machinery, heavy industrial drives, marine propulsion systems, steel manufacturing equipment, and other heavy rotating machinery operating under continuous radial and thrust loading.
