These safety chucks for the motion and rotation of expanding shafts are conceptually different from any others actually present on the market and they are particularly indicated for very high rotation speeds.
Absolutely vibration-free and silent because there is no clearance between the bearing mounted on the shaft journal and its seat.
Available in 3 models: flange or foot type, fixed version or with axial stroke adjustment (+/-25 mm), with fixed or sliding journal.
The safety chuck closes automatically with the rotation of the shaft and it can be only opened in vertical position.
The standard versions for square journal ends 30×30 / 40×40 / 50×50 mm have reduced dimensions and a very competitive price.
Available as flange or foot mounted versions in “light” or “heavy duty” executions
