Which type of bearings are commonly used in manual transmissions?

In manual transmissions, various types of bearings are utilized to support the rotating shafts and ensure smooth operation of the gearbox. Each type of bearing—ball bearings, needle bearings, and tapered roller bearings—has its specific applications based on the design and requirements of the transmission system.

Ball bearings are commonly used for their ability to handle both radial and axial loads, making them versatile for different positions within the transmission. Needle bearings, characterized by their long and slender design, are often used in areas with limited space due to their capacity to support high radial loads while minimizing friction. Tapered roller bearings can handle significant radial and axial loads, which is beneficial in components where thrust movements are present.

Since all three types of bearings play a role in different contexts within manual transmissions, the correct answer highlights that a variety of these bearing types can be used depending on specific mechanical needs and design considerations. This adaptability allows for optimized performance and durability in manual transmission systems.
