As an experienced manufacturer of expansion elements, we also produce appropriate expansion chucks for each application. The expansion chucks enable rewinding and unwinding without shafts. Their significant advantages include high torque transmission and their extensive true running accuracy. Various options such as special dimensions can be implemented to meet customers' requirements.
We also develop mechanical adapters for pushing onto existing expansion shafts or expansion chucks. These are used if frequent switches between various core diameters are required.
- the shafts are used in applications of winding / unwinding, materials e.g. paper, textile, plastic, aluminum, etc.
- available sizes for interior diameters: 12.5 mm - 500 mm
- shafts can be personalized according to the clients application
