18790/18720 TIMKEN Tapered Roller Bearing 50.8x85x17.463

Industrial applications and load-bearing performance

High durability and precise fit in bearing units

Technical data and compatibility

Main description

The 18790/18720 TIMKEN tapered roller bearing with dimensions 50.8x85x17.463 is a precision-engineered bearing unit designed for demanding industrial applications where combined radial and axial loads must be handled reliably. Thanks to its tapered roller geometry, this bearing ensures optimal load distribution, stable operation and extended service life even under continuous or variable loads.

Manufactured to strict dimensional tolerances, the 18790/18720 bearing delivers consistent performance in machinery, gearboxes, drive systems and automotive assemblies. The design allows accurate adjustment of internal clearance or preload during installation, which is critical for achieving high durability and long-term reliability. This makes it a preferred solution for professional B2B customers working with bearing housings and complete bearing assemblies.

The hardened rollers and raceways reduce friction and wear, supporting smooth rotation and energy-efficient operation. Compared to standard ball bearing solutions, a tapered roller bearing offers higher load capacity and better resistance to shock loads, making it suitable for heavy-duty industrial environments. The 18790/18720 is commonly used where bearing units must operate with high precision and predictable performance over time.

This bearing integrates easily into standard bearing housings and industrial bearing units, supporting consistent alignment and reduced maintenance intervals. Its versatility makes it suitable for production machinery, transport equipment and industrial drivetrains where reliability is critical.
