Regarding maintenance of rolling ring linear drives, what exactly does Amacoil mean by "light, periodic lubrication"?

Once per week, unless rigorous operating conditions make more frequent lubrication necessary. These conditions include long "dwell" times, extremely dirty or dusty environments, and hot (+80°C) environments. Use commercially available ball bearing grease that is free of molybdenum disulfide (MoS2 -Free).

Apply by cleaning the shaft and using a rag to spread the grease thinly and evenly. Using a brush or oil can, apply 90W oil to the reversal mechanism. Be sure to oil the spring coils, insertion points and center ring carrier.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
