30205 NTN Tapered Roller Bearing 25x52x16.25

Application and bearing design

The 30205 NTN tapered roller bearing 25x52x16.25 is designed for applications requiring the reliable transfer of combined radial and axial loads. Its tapered raceway geometry ensures precise shaft guidance, optimal load distribution and stable operation under demanding mechanical conditions. Manufactured by NTN, this bearing meets the expectations of professional B2B users looking for consistency, durability and proven industrial performance.

This tapered roller bearing is widely used in gearboxes, drive systems, machine tool assemblies, axles and industrial transmissions, where a standard deep groove ball bearing does not provide sufficient load capacity.

High durability for industrial use

The 30205 NTN bearing is engineered for long service life and resistance to dynamic loads. Precision-ground raceways and high-quality rolling elements reduce friction and wear, ensuring smooth and reliable operation even during continuous duty. The design supports stable performance under variable speeds and changing load directions, making it suitable for a wide range of industrial applications.

It can be installed as a single bearing or in matched pairs to achieve higher axial load capacity and precise axial positioning within a bearing housing or bearing unit.

Technical data and compatibility

With dimensions 25x52x16.25, the 30205 tapered roller bearing is fully compatible with standard industrial designs and commonly used bearing arrangements. It is suitable for both new installations and maintenance or replacement tasks in industrial machinery.

Main description

The 30205 NTN tapered roller bearing 25x52x16.25 is a high-performance rolling bearing designed for industrial environments where reliability and load capacity are critical. Its tapered roller construction allows efficient transmission of combined radial and axial forces while maintaining accurate alignment of rotating components.

Compared to a standard ball bearing, a tapered roller bearing offers significantly higher load capacity and better control of axial forces. This makes the 30205 NTN bearing ideal for gearboxes, drive shafts, mechanical transmissions and industrial equipment operating under medium to high loads.

For B2B customers, this bearing provides key advantages such as predictable performance, high durability and easy integration into existing bearing housings and bearing units. The robust design supports continuous operation and helps minimize downtime, making it a preferred choice for maintenance teams, OEM manufacturers and industrial distributors.

The 30205 NTN bearing is commonly specified by engineers and procurement managers seeking dependable tapered roller bearings with stable quality and proven industrial reliability.
