Clamping head for compact, powerful workpiece clamping
When it comes to securely fixing pipes, shafts, or round workpieces, the clamping head is the ideal solution. Ortlieb's compact clamping modules provide play-free, centering clamping with high power transmission, comparable to our chucks. Due to their modular design, they can be easily integrated into existing systems – whether operated manually or automatically.
What is a clamping device?
A clamping device is a precise clamping tool for the secure fixation of workpieces in lathes and automated manufacturing systems. In contrast to traditional collets or chucks, a clamping device enables particularly uniform, form-fitting workpiece clamping with high repeat accuracy.
Clamping devices are particularly used in series production, where short setup times, reproducible clamping conditions, and high process reliability are required.
Ortlieb clamping devices are designed for maximum precision and durability, making them suitable for demanding applications in CNC lathes and circular indexing machines.
Technical Characteristics of Modern Clamping Heads
A high-quality clamping head is characterized by the following features:
High runout accuracy
Even distribution of force on the workpiece
Minimal deformation even under high clamping forces
Quick changeover in mass production
Long service life with low maintenance intervals
Through precise manufacturing and coordinated material selection, Ortlieb clamping heads ensure stable workpiece clamping even at high speeds and demanding machining processes.
Clamping Head Compared to Other Clamping Tools
Compared to collets or power chucks, a clamping head offers specific advantages:
Especially high repeat accuracy
Compact design
Optimized for series production
Efficient workpiece change
While collets are often used for smaller diameters and power chucks provide high clamping forces for larger workpieces, the clamping head represents a precise and economical solution for defined component geometries.

Frequently Asked Questions about Clamping Heads
When is a clamping head preferable to a chuck?
A clamping head is the better choice when small installation sizes, high rotational accuracy, or axial access is required – e.g., in the case of hollow shafts or drawing processes.
Are special diameters possible?
Yes, Ortlieb supplies clamping heads in many standard sizes as well as custom solutions.
How is the actuation performed?
The actuation can be manual, pneumatic, or hydraulic – depending on the application and degree of automation.
