Assembly and insertion presses are used for various types of assembly, including bearing or shaft assembly, insertion or press fitting, and staking.  Bearing presses are suitable for performing assembly operations including the assembly of bearings or laminations onto a shaft; and the insertion or removal of a shaft, rod, or bearing from a wheel, pulley, plate or hub.  Insertion and press fitting operations include the insertion of pins, threaded inserts and other fastehers into plates, spring assemblies, control arms, and injector nozzles, and other applications.   Staking presses are designed or suitable for staking  assembly operations. These machines can be used to join the parts of an assembly by bending sheet tabs, or deforming a projection.
