30210 NTN 50x90x21.75 Tapered Roller Bearing

Tapered roller bearing for radial and axial loads

High durability in demanding industrial applications

Stable operation in bearing housings and bearing units

Main description

30210 NTN 50x90x21.75 is a precision tapered roller bearing designed to support combined radial and axial loads acting in one direction. This bearing type is widely used in industrial applications where high load capacity, reliability and stable operation under variable working conditions are required.

Manufactured by NTN, the bearing is produced from high-grade bearing steel, ensuring excellent fatigue resistance and long service life. The tapered geometry of the rollers and raceways enables efficient load distribution, reducing internal stresses and improving operational stability under continuous and dynamic loads.

With dimensions of 50x90x21.75 mm, the 30210 NTN bearing is commonly applied in gearboxes, wheel hubs, agricultural machinery, conveyors and heavy-duty industrial equipment. It is also suitable for assemblies such as a bearing unit or bearing housing, where precise shaft guidance and high rigidity are required. The design allows axial clearance adjustment during installation, helping optimize performance and contribute to high durability of the entire bearing system.

This tapered roller bearing is a proven solution for machinery exposed to heavy loads, shock forces and long operating cycles, offering consistent performance and reduced maintenance requirements.
