Smart Shaft Grounding solutions meet NEMA MG1 31.4.4.3 and CSI 23 05 13 specifications and are available in standard sizes or custom engineered solutions. There are applications where rotating labyrinth seals with. Contact is measured through the Smart Terminal that comes standard on every Smart CDR and Smart MGS. The typical rotating labyrinth seal incorporates a single expanding O-ring, as is found in the INPRO/SEAL style VBXX-D bearing isolator. To further ensure reliability and provide peace of mind, the Smart Ground Monitor alerts users in real time of non-optimal contact between the filaments and shaft. Isolated conductive filaments and a zero-maintenance conductive bronze rotor – unique to Inpro/Seal – provide premium connectivity in harsh conditions. The Smart MGS integrates Current Diverter Ring technology and the patented VBXX® Bearing Isolator to protect against contamination ingress and lubrication loss as well as stray currents. With proprietary conductive filaments and an innovative bearing-bronze sleeve design, the Smart CDR outperforms and outlasts other grounding rings. Standard Material: Bearing Bronze Movement: Axial- 0.13 mm 0.005 in. Most notably, Inpro/Seal Smart Shaft Grounding provides permanent protection from conduction-inhibiting shaft oxidation and offers continuous monitoring and feedback of shaft grounding performance. All VBXX-MT TECHNICAL DATA two part compound labyrinth seal consisting of a rotor and stator that protects against coolant and humidity ingress on machine tool spindles. The Smart Shaft Grounding product portfolio, consisting of the Smart CDR, Smart MGS and Smart Ground Monitor™, addresses key limitations of existing shaft grounding technologies. With the Smart Shaft Grounding product portfolio, Inpro/Seal increases motor reliability by providing voltages a low impedance path to ground away from the bearings while monitoring grounding effectiveness. Inpro/Seal VBX(140-210) or VBXX(250 & up) bearing isolators DE & ODE. The stator has a large D Groove that captures oil attempting to flow down the shaft out of the housing. Inpro/Seal bearing isolators at both the. This is a non-contacting, compound labyrinth seal that consists of a stator and a rotor. The use of variable frequency drives (VFDs) continues to expand due to their ability to reduce energy consumption and generate significant cost savings, but VFDs also induce high frequency voltages on the shaft that can damage bearings as they seek a path to ground. VBXX-D Bearing Isolator Inpro/Seal’s sealing solution for the gearbox is based on the VBXX-D Bearing Isolator.
