Rodless Cylinder Selection

1. Type selection According to the working requirements and conditions, correctly select the type of Rodless Cylinder. If the cylinder is required to reach the end of the stroke without impact and collision noise, a rodless cylinder should be selected; if light weight is required, a light cylinder should be selected;
If the installation space is narrow and the stroke is short, a thin cylinder can be selected; if there is a lateral load, a rodless cylinder can be selected; if high braking accuracy is required, a rodless cylinder should be selected; if the piston rod is not allowed to rotate, a rodless cylinder can be selected; a heat-resistant cylinder should be selected in a high temperature environment; a rodless cylinder should be selected in a corrosive environment. In harsh environments such as dust, a dust cover needs to be installed on the extended end of the piston rod. When no pollution is required, a non-oiled or oil-free lubricated cylinder needs to be selected.
2. Installation form
Determined by factors such as installation location and purpose of use. In general, a rodless cylinder is used. When it is required to rotate continuously with the working mechanism (such as lathes, grinders, etc.), a rodless cylinder should be selected. When the piston rod is required to swing in an arc in addition to linear motion, a rodless cylinder should be selected. When there are special requirements, the corresponding rodless cylinder should be selected.
3. The size of the force is the choice of cylinder diameter. The thrust and pull of the cylinder output are determined according to the size of the load force. Generally, the cylinder force required by the external load theory balance condition is selected according to different load rates at different speeds to make the cylinder output force slightly redundant. If the cylinder diameter is too small, the output force is insufficient, but if the cylinder diameter is too large, the equipment will be bulky, the cost will increase, and the gas consumption will increase, wasting energy. When designing the fixture, the force expansion mechanism should be used as much as possible to reduce the outer dimensions of the cylinder.
4. Piston stroke
It is related to the occasion of use and the stroke of the mechanism, but the full stroke is generally not selected to prevent the piston and the cylinder head from colliding. If used for clamping mechanisms, etc., a margin of 10 to 20 mm should be added according to the calculated required stroke.
5. Piston movement speed
It mainly depends on the compressed air flow rate of the cylinder input, the size of the cylinder inlet and outlet, and the size of the inner diameter of the conduit. The larger value should be taken if high-speed movement is required. The cylinder movement speed is generally 50 to 800 mm/s. For high-speed cylinders, a large inner diameter air intake pipe should be selected; for load changes, in order to obtain a slow and stable movement speed, a cylinder with a throttling device or a gas-liquid damping device can be selected, which is easier to achieve speed control. The rodless cylinder quick and easy automatic selection is included. When selecting the speed of a rodless cylinder, please note: when the horizontally installed cylinder pushes the load, it is recommended to use exhaust throttling speed control; when the vertically installed cylinder lifts the load, it is recommended to use intake throttling speed control; when the end of the stroke is required to move smoothly to avoid impact, a cylinder with a buffer device should be selected.
