The MK3 Italplant Parallel Shaft Indexers are mechanisms which convert a continuous rotary input motion into an intermittent output rotary motion. The movement transmission is obtained by means of a pair of cams having conjugated profiles, mounted on the input shaft, meshing with a set of roller followers equally spaced with respect to the output shaft.
The roller followers are preloaded in order to guarantee the precise positioning of the output shaft during the indexing and dwell.
The cam profiles are fully hardened and ground; the roller followers are mounted on hardened shafts and are supported at both ends.
Compared to the MK3 series, the MK3-E groups have input and output shafts mounted on eccentrics which guarantee their preload and zero play with optimized life and performance.
