In numerous applications recirculating ball screws are used at a higher rotation speed than the system’s first natural frequency. These conditions can cause defects on machined parts and an unacceptable noise level. Umbra has patented damping systems that, when installed inside the screw shaft, solve the vibration problems raising the system’s damping coefficient or shifting the first natural frequency.
Vibration dampers may be installed on all types of Umbra screws with a diameter of 40 - 50 - 63 - 80 mm.
