QU50397 Timken Taper Bearing Cup


QU50397 Timken® Bearing Cup is most commonly used in axle differential applications. This is a First Class, original equipment quality Bearing Cup that meets or exceeds all vehicle manufacturer specifications making it the top choice for heavy-duty applications like yours. Country of origin may vary as Timken produces Bearings in plants located around the globe, however QU50397 is almost always made in either Canada or the United States.

tech note

Always replace the cup and cone at the same time.

tech note

The matching Bearing Cone will vary by application, but for Dana-Spicer Model 60, 61, and 70 Differentials, the matching Cone is QU50398. If you need two cups and 2 cones, QU40184 Differential Bearing Set includes two each QU50397 and QU50398.

tech note

This cup is usually used on differential applications so a cup installer is not needed, however, if you need an Installer Plate for your application, order QT1804 Bearing Cup Installer separately.
