In Demand Across Many Industries
Beyond Borders
Wherever rotary motion needs to be converted into linear motion – or vice versa – and innovative, reliable solutions are required, Kammerer thread technology is the right answer. This expertise has proven itself in many industrial sectors, even beyond Germany’s borders.
Our products are therefore used worldwide: in machine tool manufacturing, general mechanical engineering, precision engineering, handling automation and robotics, medical technology, the aerospace industry, and automotive engineering.
Questions
- What do the IT1, IT3, etc. accuracy classes mean?
The accuracy grades IT1, IT2, IT3, etc. in accordance with ISO 286 specify the manufacturing tolerances for the size, form and position of workpieces. The lower the number, the higher the precision. For thread drives, a distinction is made between lead accuracy, which indicates how precisely the linear feed movement per spindle revolution is, and form and positional tolerances, which define the geometric form of the thread as well as the relative position of spindle and nut. While the IT grades define the manufacturing tolerances, lead and form/positional tolerances influence the functional precision, smooth running and backlash of the thread drive.
