Be it a round borehole, rectangular recess or a slot hole. Regardless of the opening that a component or assembly has, the pneumatic expansion gripper, "Expander", grips it tight and secure. The gripper is now available in a mini design with immediate effect – for handling particularly small parts having an internal diameter of 4.5 to 8.7 mm. 

A day that occurs frequently in gripper technology: Uneven moldings made of plastic having various perforations must be removed from the mold. Alternatively, pipes need to be gripped securely. This is where the "Expander" comes into the picture.

The expansion gripper penetrates into the part to be moved, expands uniformly once it is inside by axial compression of the elastomer, and holds the work-piece tight as a result of the force directed outwards.

The great benefit of the mini "Expander": It works safely even with non-circular openings and can, thus, be used with all perforation shapes. If special caution needs to be exercised for highly sensitive and thin-walled parts – the gripping force of the mini expansion gripper can be controlled with the help of the supply pressure as required.

Two additional arguments for the cost-conscious: The elastomer made of non-marking EPDM or highly heat-resistant silicone has a long life – if it is worn out, it can be replaced easily and cost-effectively.
