There is a piston inside the rodless pneumatic cylinder, which can move with the cylinder driven by compressed air. The piston is connected with the shuttle or carriage, and the shuttle or carriage can support the load and move it along the linear direction with the piston.
The rodless slide rail has good performance in the environment with limited space. Because the length of the slide rail is a little longer than the stroke of the cylinder, it takes up little space. For example, a rodless pneumatic air cylinder with a diameter of 25mm and a stroke of 1000mm only needs to occupy 1200mm space when opening or closing.
Other Advantages Of Rodless Cylinder
The piston in the rodless compressed air cylinder can move repeatedly and reliably in a straight line. Rodless cylinders can support high loads and moment forces. The speed of rodless double cylinder is higher than that of traditional cylinder. The rodless cylinder can be kept clean during operation to minimize the possibility of lubrication contamination. In addition, the rodless cylinder can move the load to a longer distance at a faster speed. Since there is no connecting rod in the rodless telescopic pneumatic cylinder, there is no need to worry about the bending of the connecting rod. Compared with the rod cylinder, the rodless cylinder has a smaller footprint and reduces the downtime of the equipment due to fewer components.
Generally speaking, the structure and parts of rodless air cylinder are basically the same. It is mainly composed of a cylinder tube, a piston, inner and outer sealing belts and end-cushioning end caps. The assembly of the slide is mounted directly above the piston and attached to the piston through a slot cut along the top of the cylinder, a magnet or pulley located on the piston and workbench.
The compressed air from the end cover moves the piston and bracket in any direction along the cylinder barrel. The sealing belt can avoid the leakage of air pressure to the outside and allow the bracket to move back and forth. End buffers at both ends of the rodless air compressor cylinder prevent any hard stops at the end cap.
When selecting a rodless air piston cylinder, you must consider how its load will affect its performance and consider unnecessary bending moments. Pitch, roll and yaw moments, as well as acceleration and deceleration of the carriage may affect the performance of the rodless rotary pneumatic cylinder. For vertically mounted rodless cylinders, gravity should also be considered when moving and loaded.
Compared with traditional cylinder, rodless single acting cylinder can bear higher load and torque. The traditional cylinder needs to push or pull the load by the movement of the connecting rod, which may cause the connecting rod to bend, resulting in excessive wear of seals and bearings. The speed of the traditional cylinder in the forward and return stroke is different, and this design is only suitable for short stroke.
At present, rodless cylinder is mainly used for packaging, printing, cutting, assembly and electronic manufacturing. This makes it widely used in textile, ceramics, food, pharmaceutical and chemical industries.
