This safety chuck for the dragging and rotation of the expanding shafts is conceptually different from any others actually present on the market and it is particularly indicated for very high rotation speeds that is 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 adjustment (+/-25 mm), with fixed or sliding journal. The safety chuck closes automatically with the rotation of the shaft and it can only be opened in vertical position.
The standard versions for square journal ends 30×30 / 40×40 / 50×50 mm have reduced dimensions and are economical. Available as flange or foot mounted versions in “light” or “heavy duty” executions.
