Should I lubricate my pneumatics?


Our team got a set of pneumatics, and one of them runs a little faster than the other. Would lubrication help this? If we were to lubricate them, what should we use?

The problem does come from the cylinder itself, not the tubing or valves. We switched out everything and it still has this problem of sticking, or scraping against something in the cylinder.

Perhaps it’s bent?

It may not be that it is sticky, but that the rod is bent slightly, causing it to move slower. Using a flow control fitting to slow down the faster of the two pistons will fix the problem of evening up the stroke time regardless of the cause. even if it’s a little slower it will not effect the pressure the piston receives, only the rate at which it extends.
