I have been using KrazyGrease for my road bikes bearings. I tried some environmentally friendly grease I purchased at the shop and it heated up and drained out during my first summer of cycling. I replaced the steel bearings with ceramic and decided to use KrazyGrease due to its ability to outlast most bearing grease by 10x. The friction reducer used in KrazyGrease is called Permalon (not to be confused with Permalon plastic liners etc.) It's used in high speed gear boxes in aviation jet-powered applications. You can order it an any number of mediums from small tubs, grease gun tubes, and buckets.. I still use the environmentally friendly lube for all of my bike's chain and exterior surfaces because it doesn't smell, stain, and potentially contaminate the bikes surroundings. KrazyGrease is thick, has a strong smell, and is green, so that makes it a bad option for external coatings. Anyway: I check the MSDS on the KrazyGrease and it isn't exceptionally toxic unless ingested, which the same can be said for most petro-based lubes which contain benzene etc. I talked with a local marine owner and he said KrazyGrease lasts significantly longer than other marine grade greases he has used, and my bearings are going on 5 years since I greased them. I'm thinking if you applied the grease in moderation on high friction internal components, especially effective for semi-auto pistol frame rails, this stuff could have potential for non-dusty environments. If anyone has used this on their gear I would like to hear about it. According to the MSDS, It cooks off at 500-550 degrees so barrel applications are probably not an option, but who puts grease on their barrel anyway? I figure if permalon keeps gears from self destructing at 30k+ rpm if must be good stuff. I'm willing to test it out and give results if there is an interest?
