- The square end plates fit the form factor we have already used.
- Stroke length is exactly what we need, so it is a complete COTS solution that requires no adjustment. We could make mass saving cuts, change rod material (which is currently 303 stainless steel).
- It's port inlet is 1/8 NPT, which for what it's worth, we already have compatible fittings for 1/8 NPT. This shouldn't be a driving factor, just a perk.
Disadvantages include:
- Only has two bolt attachment holes to the end plate on the payload side.
Solution No. 5: 6453K153
This piston has a 1-1/8" bore diameter made from aluminum with a 5.5" throw length. Some notable advantages of this option are:
- The square end plates fit the form factor we have already used.
- Stroke length is exactly what we need, so it is a complete COTS solution that requires no adjustment. We could make mass saving cuts, change rod material (which is currently 303 stainless steel).
Disadvantages include:
- Only has two bolt attachment holes to the end plate on the payload side.
Solution No. 6: 6556K416
This piston has a 1-3/4" bore diameter made from aluminum with a 5.5" throw length. Some notable advantages of this option are:
- Has 4 bolt holes on the payload size, which will lead to better load distribution.
- The square end plates fit the form factor we have already used.
- Stroke length is exactly what we need, so it is a complete COTS solution.
Disadvantages include:
- Doesn't represent a large mass savings
