If the pistons are joined shaft-to-shaft with a rigid coupler (like I described) one should probably check the design design using critical buckling load calculations, especially if the pistons are of a long stroke and small bore. Fortunately the actuation pressure can be reduced to help prevent the assembly from reaching its critical buckling load.
