Timken Aircraft Bearing Cup: High-Performance Solution

The Timken - Aircraft Bearing Cup 48620-20629 is a premium component designed for applications where overturning moments are a significant load component. This TDO configuration bearing offers a wide effective bearing spread, making it an ideal choice for aviation use. With the ability to be used in fixed positions or allowed to float in the housing bore, it provides unparalleled flexibility and performance.

Key Specifications and Features

This Timken bearing is part of the 48600 series and is designed in imperial units. It boasts a Y-ISP Factor of 1.78, indicating its high load-carrying capacity. The FAA/PMA approvals ensure that it meets the strictest aviation standards. It is crucial to note that Timken uses the same base part number for both automotive and aviation versions of these bearings, but aviation bearings, such as the 48620-20629, include the 20629 dash number. This version is a higher class of bearing with tighter tolerances and more stringent quality control procedures, essential for the higher RPMs and demanding conditions of aircraft applications.

Practical Applications and Benefits

The Timken - Aircraft Bearing Cup 48620-20629 is perfect for aircraft applications where precision and reliability are paramount. Its design is tailored to withstand the intense rotational speeds and loads experienced by aircraft wheels, which are significantly higher than those of automotive tires. For instance, at a 70 mph touchdown speed, a typical 17-inch diameter airplane tire rotates at 1384 RPM, compared to a typical 27-inch car tire rotating at 871 RPM. Using non-approved automotive bearings in aircraft is a violation of FAA regulations, and the Timken aviation bearing ensures compliance and optimal performance. Trust Timken for your aviation bearing needs and experience the difference in quality and reliability.
