Guess I've still got a lot to learn. Thanks.The Grinch wrote:I didn't say there are bearings as in "ball bearings" in a chain. I said there are bearing surfaces. Big difference.Sev wrote:There are no bearings in a chain. And chain wax isn't really a solid, it gets in there and stays in there. The biggest issue is that if anything is already in the roller surfaces it will be trapped in there and cause more damage.
And you're wrong about wax "staying there". It gets displaced almost immediately and is worthless for lubrication. I'm a mechanical engineer who's designed many chain-driven systems and have studied lubrication of these systems in detail. Bottom line: wax lubricants don't work despite whatever anecdotal evidence you may have heard. Stick with something like gear oil and you'll be fine.
