Norgren Short Stroke Cylinders
Short-stroke cylinders have been specially developed for applications where space is limited and where axial clearance is of the utmost importance, with low side loads and low stroke and travel speeds. We will talk about them in more detail today in our material.
What is a Short-Stroke Cylinder?
Pneumatic cylinders are actuators of pneumatic systems and are designed to convert the energy of compressed air into mechanical linear movement. Piston pneumatic cylinders are designed to convert the energy of compressed air into the reciprocating motion of the rod. When compressed air is supplied to one of the cavities of the cylinder and the other cavity is connected to the atmosphere, the piston moves along with the rod, creating a pushing or pulling force.
One of the popular types of pneumatic devices are short-stroke cylinders. They are distinguished by a limited stroke length of no more than 25 mm, with a wide diameter range of 4-100 mm. A distinctive feature of the models is the absence of covers. The housing is made of an aluminum profile in the form of a blind sleeve. On the rod side, the cylinder is closed by a disk with a spring ring.
This design further reduces the overall dimensions. The downside of this solution is reduced resistance to lateral loads, and the possibility of extremely elastic damping.
They are not used so often, so there are few options for execution. Their purpose is the use of pneumatic actuators, for which compactness is an important feature.
Short-stroke pneumatic cylinders are designed for use in confined spaces, mainly in fixing and clamping mechanisms. On the cylinder body, there are grooves for mounting magnetic position sensors. Cylinders with built-in platforms and guides are complete linear motion modules ideal for handling parts in automatic loading systems, labeling packages, moving tools, and equipment that require strict spatial orientation.
Short-stroke pneumatic cylinders have a similar design to profile pneumatic cylinders. The difference lies in the narrower covers and piston, as well as the presence of a shortened support sleeve. The product diameter range is 12-125 mm, with a stroke length of 25 mm for single-acting models and up to 500 mm for double-acting models.
With certain speed and side load limitations, however, compact cylinders proved so popular that ISO 21287 was developed for them. For models with a 32-100 mm cylinder, the hole pattern in the covers, the diameter, and the thread of the rods are the same as standard products manufactured in accordance with ISO 15552.
For compact short-stroke hydraulic cylinders, it becomes possible to use various additional options, including special temperature design, clamps, and magnetic rings for sensors.
What does Stroke Mean in an Air Cylinder?
The stroke in short-stroke air cylinders is the distance between the top and bottom dead center of the piston. It is determined by the crank radius of the crankshaft. During operation, the piston in the cylinder performs a reciprocating motion. The piston stroke tells us how many millimeters the piston and therefore the piston rod can travel.
Buy Norgren Short Stroke Cylinder
In the Eltra Trade online store, you can see the full list of available Norgren short-stroke cylinders at an affordable price. Norgren pneumatic cylinders are used in a wide variety of automation applications. We offer the widest range of pneumatic cylinders in the industry, including single-acting and double-acting cylinders with matching accessories.
Short-stroke cylinders are pneumatic cylinders with piston rods, and they all have the same great advantage: thanks to their compact design, these powerful cylinders can be used in a wide variety of applications, even in confined spaces. Compact cylinders are pneumatic cylinders with an extremely compact installation length in relation to the stroke length. They are typically used when space is extremely limited and side load requirements are low. Compact cylinders belong to the group of direct-mount cylinders and are usually installed without any special mounting aids.
In addition, thanks to a huge range of modifications, Norgren pneumatic equipment can be used in almost all industries and services: metallurgy, engineering, energy, woodworking and foundry, construction, mining and oil refining, printing, transport, handling equipment, stage equipment.
If you have any difficulties with the selection of suitable equipment, you can always use the help of experienced Eltra Trade employees who will give their recommendations on the use of pneumatic devices for various purposes.
