[QUOTE="Shadowrider, post: 4135238, member: 3099"] Haha. Yea, I hear that. Way back when I worked in machine shops we had a horizontal CNC machining center. Hitachi Seiki. Very well made and reliable machine that we ran every single day. Several years in, it needed the spindle bearings replaced, so we had them send a service rep to do it. They had a fairly large presence in the U.S., had service centers and all support parts, etc. I got to work with the Japanese guy they sent to do the replacement. We tore it down and cleaned everything up. The new bearings arrived (from Japan) with a small 35mm film canister like container of grease that had maybe a teaspoon full of grease in it. It was completely unmarked and looked a whole lot like vaseline. He said that's definitely not what it was and was very expensive stuff. He applied a light film very, very meticulously over each individual roller ball and on the mating races, put the seals in and we installed them. And that's it. He probably used half of what they sent and he sent the remainder back! The bearings were in no way packed at all. He said that would increase heat from "interference restriction". Whatever it was, it worked. I worked there for a good time after and ran that machine a lot. It had zero issues out of the spindle bearings. These were state of the art precision, high speed, HD bearings. Not cheap at all. [/QUOTE]
