Tool Changers
Tool changers enable your robots to automatically switch between different end-effectors, grippers, and tools, maximizing productivity and flexibility. Proax supplies manual, pneumatic, automatic, and magnetic tool changers from Zimmer Group and other leading manufacturers. Stock items ship same-day across Canada, with short lead times on special orders. Free pickup available at all 13 Canadian locations.

Why Tool Changers?
One robot, multiple tasks. Tool changers eliminate manual changeovers and enable your automation system to handle diverse operations—from welding to assembly to material handling—without investing in multiple robots.
- Manual – Up to 40kg capacity, operator-actuated, cost-effective
- Pneumatic – Up to 500kg+ capacity, fully automated, high-frequency changes
- Manu-matic – Up to 29kg capacity, works without air supply
- Magnetic – FDA-compliant, hygienic design for cleanroom applications
All systems follow ISO 9409-1 standards for universal robot compatibility with ABB, FANUC, KUKA, Yaskawa, Universal Robots, and more.
Quick Selection Criteria
Payload capacity - Match to your heaviest tool + workpiece weight
Change frequency - Manual for occasional, pneumatic for high-frequency
Media requirements - Pneumatics, electrical, vacuum, communication protocols
Environment - Cleanroom rating, IP protection, FDA compliance

Frequently Asked Tool Changer Questions
They're the same thing. Tool changer, quick changer, and coupler are interchangeable terms for devices that enable quick robot tool connection and disconnection.
Pneumatic tool changers complete changes in 1-3 seconds. Manual systems take 5-15 seconds. Manu-matic systems with tool racks change in 2-5 seconds.
Yes. Select a model matching your cobot's ISO 9409-1 flange size and payload capacity. Magnetic and lightweight pneumatic changers are popular for collaborative applications.
Quality pneumatic tool changers feature spring-loaded locking mechanisms that maintain grip even during complete pressure loss. The tool remains securely locked until pressure is restored and an unlock signal is given.
Calculate your heaviest tool weight plus maximum workpiece weight, then add 20-30% safety factor. For example: 8kg tool plus 15kg workpiece = 23kg. With 30% safety factor, you need approximately 30kg capacity. Always round up to the next available size.
