Zimmer WWR Automatic Tool Changer Review: Specs, Price and Applications
The Zimmer Group WWR series is an automatic tool changer that lets a robot switch tools without operator intervention. It holds the tool securely during a pressure drop using a redundant system of a spring accumulator and a self-locking mechanism.
An extremely flat design reduces the moment load on the robot, often allowing a smaller and less expensive robot size. A range of media transfer modules can be configured to the application.
Quick Verdict
A safe and compact automatic changer for multi-tool cells. Redundant locking addresses the key risk of automatic changers: dropping a tool when air fails.

Design and Operating Principle
In an automatic changer, a pneumatic piston drives locking elements that couple the tool to the robot. If air fails, a non-redundant design could release. The WWR combines a spring accumulator with a self-locking mechanism so the tool stays locked even without pressure.
Flat construction keeps the tool's centre of gravity close to the flange. Lower moments mean the robot can carry heavier tools or a smaller robot can be used.
Media modules transfer air, electrical signals, power or fluids, so each tool receives what it needs automatically.
Integration and Selection
Choose the size for tool mass and moments, then configure media modules. Design tool stands for reliable docking and add lock and tool-ID sensing.
Validate tool change sequences and air-loss behaviour during commissioning.

Who Should Consider the Zimmer WWR Automatic Tool Changer?
The WWR suits multi-tool robotic cells requiring safe, automatic changeovers.
Price and Availability
Price: Request a quote. Zimmer Group prices the WWR by size, options and quantity, so the final figure depends on the exact configuration. Budget for the complete tooling package, including fingers or adapters, mounting, air or electrical connections and commissioning time, rather than the module alone.
