Anyone know if the vex double acting cylinder is available or an identical version that is allowed for vrc?
You can buy the same cylinder direct from SMC pneumatics, or a reseller such as radwell.com or robotmesh.com. Take a look at the Vex product page, and the SMC part numbers are listed so you can order the right parts.
Would NCJ2D10-200S work, since NCJ2D10-200 isn’t available or can i only use NCJ2D10-200 for vrc.
NCJ2D10-200 is a VRC legal double acting piston and NCJ2D10-200S is a VRC legal single acting piston.
Breaking down what that whole code means
NCJ2 just means a round body piston
D is for a double clevis mount
10 is the bore diameter which is 3/8th
200 refers to the stroke/amount the piston can extend which is 2 inches
S refers to if its a single acting, if its present its a single, if not its a double acting
The links I use to order pistons of VRC legal size. SMC almost never keeps any items in stock, you just have to order it and wait 4 weeks for them to make it and ship it to you.
