A system, in certain embodiments, includes a barrier with magnetic coupling between opposite sides of the barrier. For example, the system may include a first member with a first magnet that translates along with the first member, and a second member having a second magnet that translates along with the second member. The system also may include the barrier completely isolating the first member from the second member, wherein the first magnet magnetically couples with the second magnet through the barrier to impart translational motion from the first member to the second member.

1. A system, comprising: a compressor;a crankshaft;a motor coupled to the crankshaft;a first member coupled to the crankshaft, wherein the first member comprises a first magnet that translates along with the first member;a piston;a second member coupled to the piston, wherein the second member comprises a second magnet that translates along with the second member; anda barrier completely isolating the first member from the second member, wherein the first magnet magnetically couples with the second magnet through the barrier to impart translational motion from the first member to the second member. 2. The system of claim 1, wherein the first member comprises a shaft and the second member comprises the piston. 3. The system of claim 1, wherein the first member, the second member, and the barrier are disposed in a concentric arrangement about one another. 4. The system of claim 3, wherein the first member is disposed concentrically about the barrier, and the barrier is disposed concentrically about the second member. 5. The system of claim 4, wherein the first magnet comprises a first annular magnet, and the second magnet comprises a second annular magnet. 6. The system of claim 1, wherein the first and second magnets each comprise a permanent magnet, an electromagnet, an active magnet, or a combination thereof. 7. The system of claim 1, wherein the first and second members each comprise hollow annular portions. 8. The system of claim 1, wherein the barrier is completely seal-free between opposite sides of the barrier. 9. A system, comprising: a first reciprocating member having a first magnet, wherein the first magnet is configured to transfer reciprocal motion of the first reciprocating member to a second reciprocating member via a second magnet coupled to the second reciprocating member, and wherein the first reciprocating member comprises a connecting rod configured to couple with a crankshaft. 10. The system of claim 9, wherein the first magnet is configured to magnetically couple with the second magnet through a barrier that completely isolates the first and second reciprocating members. 11. The system of claim 10, comprising the barrier, wherein the barrier has a can-shaped geometry. 12. The system of claim 9, wherein the first member comprises a piston. 13. The system of claim 9, wherein the first reciprocating member and the first magnet are configured to be in a concentric arrangement with the second reciprocating member and the second magnet during the reciprocal motion. 14. A system, comprising: a magnetic coupling barrier configured to completely isolate first and second members on opposite sides of the magnetic coupling barrier, wherein the magnetic coupling barrier is configured to enable magnetic coupling and transfer of translation motion between first and second magnets coupled to the respective first and second members, and wherein the magnetic coupling barrier comprises a can-shaped geometry having an annular wall and a closed end, and the magnetic coupling occurs through the annular wall, the closed end, or a combination thereof. 15. The system of claim 14, wherein the magnetic coupling barrier is completely seal-free between the opposite sides. 16. The system of claim 14, comprising a machine having the magnetic coupling barrier. 17. A system, comprising: a drive;a crankshaft coupled to the drive, wherein the drive is configured to rotate the crankshaft;a first reciprocal shaft coupled to the crankshaft, wherein the first reciprocal shaft comprises a first annular magnet; a second reciprocal shaft having a second annular magnet;a piston coupled to the second reciprocal shaft;a gas compression chamber disposed adjacent the piston; anda can-shaped barrier in a fixed position that isolates the first and second reciprocal shafts, wherein the can-shaped barrier completely blocks gas from leaking from the gas compression chamber to an opposite side having the first reciprocal shaft, the first annular magnet magnetically couples with the second annular magnet through an annular wall of the can-shaped barrier to impart reciprocal motion from the first reciprocal shaft to the second reciprocal shaft. 18. The system of claim 14, wherein the first member comprises a connecting rod configured to couple with a crankshaft.
