Schunk - SWS Quick-Change System: Modular, Robust, and Flexible

The SWS is a tool changing system used to automatically change end-of-arm-tooling on robotic and gantry systems wherever changeover times between a robot and a tool are needed.

The SWS is a tool changing system used to automatically change end-of-arm-tooling on robotic and gantry systems wherever changeover times between a robot and a tool are needed. The SWS system consists of the SWK quick-change master and the SWA quick-change adapter. The SWK mounted on the robot incorporates a patented fail-safe locking mechanism and couples with the SWA mounted on the tool. A pneumatically driven locking piston ensures that the connection is secure and provides pneumatic and electric pass-through to supply controls to the robot tool.


SWS tool changers increase productivity by enabling a robot to perform multiple tasks which reduces overall cost and increases profits. By equipping robots and gantries with SWS tool changers, change over time between tasks is reduced to seconds reducing downtime and increasing production. SCHUNK offers SWS tool changers in sizes to fit any industrial robot from the smallest SCARA to the largest 6 axis robot. Contact SCHUNK to find out how we can help you with your application today.

T.J. Davies' Retention Knobs

T.J. Davies' Retention Knobs

Our retention knobs are manufactured above international standards or to machine builder specifications. Retention knobs are manufactured utilizing AMS-6274/AISI-8620 alloy steel drawn in the United States. Threads are single-pointed on our lathes while manufacturing all other retention knob features to ensure high concentricity. Our process ensures that our threads are balanced (lead in/lead out at 180 degrees.) Each retention knob is carburized (hardened) to 58-62HRC, and case depth is .020-.030. Core hardness 40HRC. Each retention knob is coated utilizing a hot black oxide coating to military specifications. Our retention knobs are 100% covered in black oxide to prevent rust. All retention knob surfaces (not just mating surfaces) have a precision finish of 32 RMA micro or better: ISO grade 6N. Each retention knob is magnetic particle tested and tested at 2.5 times the pulling force of the drawbar. Certifications are maintained for each step in the manufacturing process for traceability.
