<div class="yiv6416211874MsoNormal"><span style="font-family:"Garamond", "serif";color:#44546A;" lang="EN-GB">1.The coating adds some thickness (variable on demand but approx. 5-10 microns), does that need to be taken into consideration in the clearance?</span></div>

<div>I buy my TR-4 tri-metal bearings from BP Northwest and then send them to Calico Coatings for that part. Not exactly what you're looking for, but Calico Coatings is who I've used for over 10 years and am very happy with. Just be sure to mail them them Denver North Carolina - I once sent to Denver Colorado instead. That was a delay of game.</div>
