Timken 305DD Manual Transmission Bearing

The Timken 305DD is a manual transmission input shaft bearing built for precise fit, stable rotation, and low noise in drivetrain service. With a 25.00 mm inside diameter, 62.00 mm outside diameter, and 17.00 mm width, it matches common OE-style bearing dimensions for select manual transmission applications.

Timken deep groove bearing construction is engineered for smooth operation under proper lubrication, with tight tolerances and a refined surface finish that support consistent performance. This bearing follows ISO dimensional standards and is interchangeable with competitor parts in the same size class.
