Pneumatic Clevises

Hello all,

I was wondering where some of you might get your Pneumatic Clevises, as the ones VEX gives with their kit are not the SMC version. What do teams do if they need clevises but don’t buy from VEX.

I am kinda nitpicky about my parts and would much rather buy something designed for use with the product instead of fashioning my own out of scrap.

Could I design one for use with VEX parts, Yes. But lets be honest, a real clevis would be far more accurate.

If VEX could sell the ones they have and provide CAD that would be great! However an alternative would be to allow teams to buy their own from SMC this would be pretty awesome IMO. But Nonetheless VEX has their rules and I will abide to them.

This might not be the right time or place to post this. The Q&A really needs to open. Its been far to long.

Also, Is it legal to use just regular L fittings for the pistons and accumulators?

I think most teams just use screws or axles to secure their pnuematic cylinders. I have never used the clevis pins that come with the cylinders.

They will probably only let you use the parts that come from VEX or from SMC with the same part numbers.

I was talking for the piston rod clevis, I know that they come with some. Just wondering where to get them.

Piston rod clevis? I’m not sure what you’re talking about now.

Are you talking about the rod pivot? I think the pins that they come with are for the cylinder mounts.

Cody’s Pnuematics kit has clevises, Hrm Doesn’t matter now, Worked around it Sacrifice my plastic block but no big deal really!

Well now I’m curious as to what they are…
Do they go on the rod pivot or the cylinder mount?

Rod Pivot, and Cylinder Mounts. Made one for each.

Check out this picture. It is a clevis for a piston (NOT VEX)

The rod pivot brackets that come with the VEX pneumatics are pretty thin, so I was wondering why anyone would bother making a legitimately sturdy pin (instead of a screw). It makes a lot more sense to have pins for the cylinder mount (which is very similar to the one in that picture) because it’s a beefier connection point.
