Schunk Power Lathe Chuck (ROTA-THW plus) - ISO 702-4
QUANTITY
Universal 3-jaw power chuck with jaw quick-change system and maximum operating safety.
Definition clamping force
The clamping force is the arithmetic sum of the individual forces occuring at the chuck jaws, distance “H“ at maximum pressure and maximum torque. The specifications exclusively refer to the grease used by SCHUNK.

- Convenient jaw quick-change system - Minimizing set-up times and costs
- Large through-hole - Machining of all standard pipe diameters
- High efficiency of the wedge bar system - Process-reliable clamping due to high clamping forces
- High jaw quick-change repeatability - No reboring of already machined jaws necessary
- Optimized lubrication system - Consistently high clamping forces are ensured
- Modular center sleeve system - Optimum adjustment to new clamping tasks due to exchangeable center sleeves
- GBK straight-serrated base jaws - Compatible to ROTA-G and system “R“ (Reishauer)
- Two mounting bolt circles - For fast and direct attachment to all commercially available spindle heads
- All functional parts are ground and hardened - Ensures a long service life
The wedge bar power chuck ROTA THW plus is distinguishes by its high flexibility. This ensures the integrated jaw quick-change system as well as the modular exchangeable center sleeve system. By using of the jaw quick-change system, the chuck jaws don't have to be turned out again.
Aside from high precision, the ROTA THW plus was engineered to be handled easily and safely during the jaw change. Only when the base jaw is properly engaged in the serration of the wedge bar, the wrench can be easily removed from the chuck.
