Spann set for non-playable power transmission in industrial applications
When precise torque transmission without play is essential, clamping sets are the first choice. Ortlieb provides high-quality fasteners for machine and drive technology – ideal for applications where screw connections or keyways reach their limits. Assembly is simple via friction connection – completely without groove or key.
What is a clamping set?
A clamping set is a mechanical clamping system for securely fixing tools or components within a defined interface. In machine tools, clamping sets are responsible for reliably fixing tools in the spindle and transmitting high axial tensile forces.
In the area of tool clamping, clamping sets are particularly used in SK and HSK interfaces. They ensure play-free, repeatable clamping and enable automatic tool changing in modern CNC machines.
Ortlieb develops clamping sets for the highest requirements for precision, load capacity, and continuous operation.
Technical Requirements for Clamping Sets
A high-quality clamping set must fulfill several functions simultaneously:
High clamping force for secure tool fixation
Precise centering in the spindle
Minimized wear during repeated change operations
Durable clamping force even at high speeds
Compatibility with automated tool changing systems
Through precise manufacturing and optimized spring and material design, Ortlieb clamping sets ensure reliable tool clamping even under demanding production conditions.
Clamping Sets in the Tool Clamping System
Clamping sets are a central element of the entire tool clamping system. Together with spring clamps, release units, and spindle systems, they form the basis for a safe and process-stable tool change.
Depending on the interface, different variants are used, such as:
These are specifically tailored to the respective tool holder and meet the requirements of modern high-performance machining.

Frequently Asked Questions about Clamping Sets
Are special sizes feasible?
Yes – we manufacture clamping sets according to your specifications or adopt existing standard sizes.
How does the disassembly proceed?
By loosening the clamping screws and possibly using pull-out threads – easy and damage-free.
Are clamping sets reusable?
Yes, with correct application – all components are robust and designed for reuse.
