Straight gears and racks are the classical components for mechanical transmissions of rotary and transverse movements between moving parts of machines.
This explains why these components are so widespread and are used to such a large extent in various sectors of general mechanics such that in practice it is impossible to find a rigid type power transfer drive chain which does not adopt these basic components.
However, the needs of industry are extremely complex as regards the performance required from the gear and the rack are designed. This is why proposing a product intended to meet any need expressed by industrial experience would be unthinkable.
