Newport MKS Vibration Isolator, Mechanical, 5 lbs. (2.3 kg) to 12 lbs. (5.4 kg) VIB100-0512

The VIB100-0512 bearing is a self-contained unit that provides both vertical and horizontal isolation from 5 lbs (2.3 kg) to 12 lbs (5.4 kg). The isolators feature a 7.3Hz vertical resonance frequency that begins isolating at 9Hz and a horizontal resonance of 4.6Hz with isolation beginning at 8Hz. This is sufficient performance to eliminate 85% of vibration noise seen within typical laboratories. The VIB100 bearings attach to the VIBe base plate via specially designed brackets that feature a threaded aperture to allow leveling adjustment of the platform. Superior Mechanical Design VIBe™ technology works in horizontal direction by utilizing ball bearings sandwiched between precision raceways, forming the plane of isolation. The balls that displace between the raceways due to micro-vibrations are restored to the neutral position by gravity, which acts as a non-linear spring. Since the spring force (i.e., the restoring force) is non-linear, it is constant and independent of the frequency and amplitude of the input vibrations, meaning the balls’ oscillating motion has no “natural” frequency. Instead, the motion has an infinite number of frequencies, one for each increment of displacement, which makes the resonance between the two halves of the plane of isolation physically impossible. As a result, the isolator filters out a broad band of input vibration frequencies and ensures a constant level of vibration transmission reduction. Vertical vibration isolation is addressed by the Newport's proprietary, nonlinear spring mechanism with near zero tangential stiffness for vibrations. The natural frequency of the spring remains relatively low and constant across a large range of spring compression, effectively isolating the vertical vibrations. Standard and Adjustable Mounting Options standard and adjustable mounting options are available for VIB100 isolators to be mounted to a tool frame or other supporting structure. Compact Vibration Isolation Platforms VIB100 isolators are designed specifically for applications that require small footprint. VIP100 vibration isolation platform consisting of 0.5 in. thick aluminum top with threaded 1/4-20 or M6 mounting holes and 4 of the VIB100 isolators accommodate the most tight spaces in OEM and research applications.
