I need a long service life linear motion solution for high part cycle, filthy environment. Cycle quantities in the millions / year.
Actuator will be pneumatic, and while one of the options with two linear bearings / and a centered cylinder would be the cats ass for this situation, the cost at $350 is too great.
Actually, the purchase cost isn't bad, it's the replacement cost as I expect to be wearing these out.
So going back to basics with a $40 off the shelf cylinder, I am left looking at linear motion/guide options.
Precision is not necessary, only enough to keep it from binding.
Lateral load is small, really not much more than the weight of the rods themselves, and torque is pretty small as well. I could probably get reasonable life with simply hardened linear shafting rod and a long bronze bushing, but, I'm curious if there are better options out there.
