Remarks:
⁽¹⁾ Based on 1 x 10⁶ revolutions L₁₀ life, for the ISO life-calculation method. C₁₍₂₎ is the double-row radial value.
⁽²⁾ Consult your Timken engineer for instructions on use or review the Timken Engineering Manual on timken.com/catalogs.
⁽³⁾ Based on 90 x 10⁶ revolutions L₁₀ life, for The Timken Company life-calculation method. C₉₀ and Cₐ₉₀ are radial and thrust values for a single row. C₉₀₍₂₎ is the double-row radial value.
⁽⁴⁾ These maximum fillet radii will be cleared by bearing corners.

TDO Type Timken Tapered Roller Bearings represent a specialised category of precision-engineered roller bearings designed and manufactured by The Timken Company, a renowned leader in the bearing industry. The "TDO" designation stands for "two single-row, double outer," and these bearings are designed to handle both radial and axial loads simultaneously, ensuring reliable performance in a variety of demanding applications.

Timken TDO Type Tapered Roller Bearings feature two single-row tapered roller bearing assemblies that are mounted in a back-to-back arrangement. The inclusion of a central spacer between the outer races of the bearing assemblies enhances rigidity and load distribution, optimising their ability to withstand heavy loads and high-speed conditions. The configuration also allows for easy adjustment of bearing clearance, providing flexibility for different operating conditions.

These bearings are engineered with precision and manufactured using high-quality materials to meet Timken's stringent quality standards. The tapered roller design ensures efficient load distribution and reduces friction, resulting in enhanced durability and extended service life. Timken's expertise in metallurgy and heat treatment further contributes to the bearings' robust construction and performance reliability.

TDO Type Timken Tapered Roller Bearings find application in a diverse range of industries, including automotive, aerospace, mining, and more. They are commonly employed in critical components such as gearboxes, axle systems, and other power transmission equipment where the need for both radial and axial load-bearing capabilities is paramount.

Timken's commitment to innovation and quality assurance makes their TDO Type Tapered Roller Bearings a preferred choice for engineers and manufacturers seeking reliable, high-performance bearings for their applications. Whether in heavy machinery or precision equipment, Timken TDO Type Tapered Roller Bearings play a crucial role in ensuring the efficiency and longevity of mechanical systems.
