Helwig Carbon bpk-4 self grounding brush with holder. VFD's cause a term called fluting. Basically electricity travels through the shaft causing bearing failures. This eliminates any voltage by grounding it out directly. If your bearings are only lasting a couple of months and you are using a vfd , this is the culprit! They will pay for themselves if they save you from changing bearings just once.These are easy to install and you can use them up to a 4 inch shaft. Here are the measurements for the BPK-4.
.375"×.25" and .50" thick.
