Schunk low profile quick change robotic handling module can handle pallets up to 350 kg

The NSR-A allows attachments that are very close to the clamping station and pallet, while allowing enough space for the components and the axis motion. The module can be equipped with a Schunk standard media transfer for pneumatics, electrics or fluids. At a dead weight of 1.6 kg (size 160), the NSR-A has a locking force of 14 kN. It is suitable for reliable handling of pallets up to 350 kg with an overall area up to 400 by 400 mm for the handling of tools. The handling of such a mass is made possible by the Schunk patented fast stroke and clamping stroke locking system. The unit is form-fit and self-locking. Unlocking could be done with oil-free air as a pneumatic system pressure of 3.5 bar is adequate. High strength, hard coated aluminium has been used for parts outside the power flow to achieve an optimum ratio between rigidity, robustness and weight. The parts inside the power flow are made of hardened stainless steel. The module is completely sealed to protect it from chips and coolant. The locking and unlocking process is controlled by magnetic switches while the pallet and tool presence is interrogated by inductive proximity switches. The repeat accuracy is specified at 0.02 mm.
