This package covers two important aspects of mechanical drives. A variety of couplings are introduced while learning various shaft alignment methods. Installation methods for several types of bearings and seals are also detailed.

A fundamental aspect of mechanical drives is the axial transmission of torque from a driving machine to a driven machine. This is achieved by joining the shafts of each machine through a device called the coupling. A key requirement of any coupling is the alignment of the shafts. The topic Shaft alignment and couplings introduces those aspects and presents couplings and shaft alignment methods suitable for various operating conditions. An optional Laser alignment of shafts add-on is also available.

The topic Bearings and seals deals with the inner components of a machine. Using real applications such as a gearbox, a pump and a wheel hub, students learn industry-proven methods for installing and removing bearings and seals in housings and on shafts. Essential concepts of bearings lubrication are also covered.

The manuals of the Level 3 package guide the students step-by-step during their learning process with several photos and illustrations. The main hardware is stored on panels for quick identification and inventory control.
