A rodless cylinder is a cylinder that is directly indirectly connected to an external actuator mechanism by a piston follows the piston to achieve reciprocating motion.
The advantage of cylinder is saving installation space. It can be divided into magnetic coupling rodless cylinder (magnetic cylinder) mechanical rodless cylinder. The working principle of rodless cylinder is the same as that of common cylinder, but the external connection mode sealing mode are different. There is a piston in the rodless cylinder, but there is no piston rod. The piston is installed in the guide rail. The external load is connected to the piston is driven by the intake air.
The working principle of rodless cylinder is the same as that of common cylinder, but the external connection mode sealing mode are different. The schematic of the rodless cylinder is hollow on both sides. The permanent magnet in the piston rod drives another magnet (moving part) to the outside of the piston rod, which requires a high degree of environmental cleanliness. There is a piston in the rodless cylinder, but there is no piston rod. The piston is installed in the guide rail. The external load connects the piston to the piston actuates it with the intake air. In general, rodless cylinders will be equipped with corresponding air buffers. This is because when the cylinder is running, the internal thrust of the air pressure can be used to generate a certain amount of inertia. This will cause the piston to move back forth stop immediately, so it often touches the end caps at both ends of the cylinder. In order to prevent this situation, it is necessary to equip with gas buffer device, that is, its function is mainly to protect the end cover, which can prevent the end cover being hit by the piston.
