What's The Rodless Cylinder?

A rodless cylinder is a pneumatic device capable of moving a load in a linear path with compressed air. But the load moves directly with the piston through a link block that moves with the piston.
When the stroke of the cylinder is overlong, the use of a cylinder with a piston rod easily causes the piston rod to bend and deform. Therefore, a piston-less cylinder is often used to solve this problem. The occasions where travel and installation space are restricted; for example, pushing in and moving workpieces, opening and closing of mechanisms, lifting of objects, door control, and material conveyance.

The Advance of Rodless Cylinder

They do not have the cylinder piston rods as ordinary cylinders but use the pistons to directly or indirectly connect the internal actuators, and then the pistons perform directly or indirectly to realize linear motion of the objects. This kind of cylinder has the biggest advantages of simple structure and saving installation space and is especially suitable for the occasions of small stroke and long stroke.

What's The Pneumatic Linear Actuator?

Pneumatic linear actuators are also called as air cylinder or pneumatic cylinder. They are designed to move object in a straight line and are one of the simplest, most cost-effective, and straightforward ways to accomplish linear motion. Introduction to Linear Actuators Linear actuators are utilized throughout the industrial sector, in factory automation, transportation, packaging, life sciences, and much more.

Pneumatic linear actuators are engineered to convert compressed air into a linear motion, most commonly with a piston rod extending and retracting, but can also be designed with a carriage that moves on the cylinder tube or guideway.

Construction and materials

Most linear actuators are constructed of aluminum, such as Parker’s P1F-S series, which is suitable for a large number of applications. However, if you’re operating in a challenging environment or one that requires washing down such as food processing and packaging, then you may require one constructed of stainless steel to prevent contaminants caused by corrosion, such as Parker and Dg-pnetic.
Some offer wiper and metallic scraper options that will remove external debris and adherents from the piston rod. Enhanced surface treatments, such as powder coatings and anodizing of the two typical pneumatic cylinder materials (aluminum and steel) can also protect against contamination in caustic washdown environments.

Advantages of Pneumatic Linear Actuators

A pneumatic linear actuator is very simple. Most aluminium cylinders have optimal maximum pressure ratings which allows for a range of forces. They are often used in areas of extreme temperatures due to the safety of using air rather than hazardous chemicals or electricity.
It is a low-cost option.

What's The Guided Cylinder?

The guided cylinder is composed of a guide rod or slider parallel to the piston rod and the cylinder as a whole, or a cylinder is composed of two parallel pistons and piston rods. In the double-piston rod cylinder, the heads of the two piston rods are mounted by a flange, which prevents the rotation of the piston and obtain double output force at the same time.

This cylinder has a compact structure, high guiding accuracy, and can withstand large lateral loads and moment of force. It can be used to withdraw, lift and position the workpiece on the conveyor line.

For the guide rod, normally there are two types rail bearings , one is the sliding bearing and ball shaft. The sliding bearing type has good abrasion resistance and can withstand lateral load more than 2 times larger than that of the stopper cylinder. It is suitable for use as a stopper. The ball bearing type can make high-precision smooth movement, has a long life, and is suitable for moving and lifting workpieces on the conveyor belt.

How Many Types Guided Cylinder?

Normal Guided Cylinder

The simplest guided cylinder, which consists of a double-acting standard cylinder and two guide rods. In order to prevent installation deviation, the cylinder piston rod is connected to the flange plate of the guide rod. The guide rod is drove by cylinder piston rod, And move together. We supply the guided cylinder s with the bore size is from 10mm to 100mm, and the stroke from 10mm to 500mm.

Dual Rod Cylinder or Twin rod Cylinder

Simply, there are two parallel piston rods in one cylinder. And the two piston rods’ motion are in sync. There are two types of dual rod cylinder.

One is there are two pistons in a cylinder, and two rods are installed on each piston. The two piston rods are linked by a alloy connecting plate. This can ensure that the two piston rods are synchronized during movement. The two rods not only a perform guiding function, but also double output force.

Another type of double-rod cylinder is a cylinder with only one piston, but two piston rods are installed on the piston. Compared with ordinary cylinders, the output of this cylinder will not change much. So installing two piston rods is only for guiding purpose. Double-piston cylinder’s bore size is from 10 to 32mm, stroke range is from 10 to 100m. But the bore size of the second dual rod cylinder is same as the ordinary cylinder.

Long stroke precision guide cylinder

It consists of a magnetic coupled rodless cylinder and guide rod or guide rail. The rodless cylinder drives the slider moving together. The guiding device has the characteristics of high precision, which can prevent torsion and increase the load capacity. The cylinder bore is 10 ~ 40mm, and the stroke range is 10 ~ 1500mm.

Stop sensor assembly is installed in the groove of the installed alloy rail strip and is used to send a signal at the stroke terminal. But more position switches can be installed on the rial strip to detect the movement position of the cylinder.

Precautions Of The Rodless Cylinder

1. The compressed air should be filtered by 40um filtration.
2. The cylinder body should be installed on a flat surface. Once the guide rod is bent or twisted, the movement obstruction will increase sharply, the bearing will wear out quickly, and the performance will decrease.
3. The sliding surfaces of the piston rod and guide rod must not be damaged, so as to avoid damage to the seals, and finally lead to the air leakage.
4. There is a danger of sudden action by cylinders if the sliding parts of machinery are twisted, etc., or changes in forces occur.
5. There may be cases in which a speed-reduction circuit or a shock absorber is required.

The Consideration When Choose The Rodless Cylinder.

The following criteria should be considered while selecting a rodless cylinder:
Stroke speed: This is the speed at which the piston moves within the cylinder. This would depend upon the air pressure supplied at each port and the load.
Carrier Load: The carrier must be able to support and move the mounted load safely and efficiently and align the rod axis with the load and direction of movement when connecting
Dead length: Ensure sufficient space for installing maintenance activities.
Stoke: Use the product within the limits of the maximum usable stroke. The piston rod will be damaged if operated beyond the maximum stroke.
Air pressure: As the piston is driven my compressed air, there must availability of constant air pressure ,and filtered air supply.
Bore Size: Bore size can be chosen according to the capacity range required for the application. For a cylinder to perform at maximum capacity, larger bore size should be considered.
