Magnetic bearing for supporting an rc piston

A compressor with a magnetic bearing, the compressor comprising a piston, a crankcase assembly and a cylinder;

• the magnetic bearing being configured to support the movement of the piston sliding into the cylinder comprised in the compressor, wherein the piston comprises a first rod which connects the piston to a crankcase assembly of the compressor and an extension rod, which is connected to the first rod, wherein the magnetic bearing comprises:
• a first group of magnets arranged on a first side of the extension rod of the piston;
• and
• a second group of magnets arranged on a second side of the extension rod of the piston, wherein the first side and the second side are opposing sides in a radial extension of the extension rod,
• wherein the magnetic forces exerted by the first group of magnets and the second group of magnets respectively allow the piston to be supported during its movement.
