PRESS RELEASE

SALT LAKE CITY, UT—Parker has launched the ProTech self-grounding (SG) bearing isolator for 100% exclusion of contaminants and dissipates electrical shaft voltages caused by variable frequency drives (VFD). The carbon brush assembly in the ProTech SG quickly and transfers the transient shaft voltages to the conductive PTFE bearing isolator body, then to motor ground. ProTech's seal adds value by decreasing downtime common with bearing pitting/fluting damage, and prevents bearing damage caused by contamination.

ProTech is manufactured from a proprietary conductive PTFE material for a range of operating capabilities, including high or low temperatures and extreme chemical environments.
