Question Nominal Stroke???

What exactly is nominal stroke on a linear actuator?? And can I find a 1 inch nominal linear actuator online? Or do we have to build one ourselves??
Thanks,
Taggerun

"Nominal" means "we designed it to actuate x inches every time, but your conditions/use may vary, so we can't guarantee it will actuate x.0000000 inches every time."

Basically, they say it's a, for example 1" stroke, but they can't guarantee it'll be exactly that for every use and condition.

Re: Nominal Stroke???

If the manufacturer calls it a 1" stroke, and you buy one and measure the movement to be 1.05", then it's still legal, because the nominal spec is 1" (manufacturer spec).

Re: Nominal Stroke???

Remember it still has to be powered by a legal FRC motor. Amazon is full of options, but AndyMark is the only one I know of that sells COTS legal linear actuators for FRC.

If it's powered by a motor, then it is just a gearbox and it can have any stroke. (e.g. DART linear actuators). This rule is referring to non-DC brushless linear actuators like solenoids and the like. They can only have a 1" nom. stroke max.
