The norelem pneumatic cylinders carry out a rectilinear movement using compressed air. Pneumatic cylinders are also sometimes (but rarely) called compressed air cylinders. The pneumatic cylinders can be operated with filtered dry air or lubricated air and unlubricated air. They are suitable for ambient conditions with a temperature range of -20 °C to +80 °C.
Due to the robust design, these pneumatic cylinders can be used for diverse applications in many different sectors. Examples of applications for pneumatic cylinders are Injection moulding tools, conveyor, drive or handling technology.
The materials used in the entire range of pneumatic cylinders from norelem are aluminium or stainless steel for the cylinder tube, aluminium or die-cast aluminium for the end cap, stainless steel or high-carbon steel for the piston rod and polyurethane or acrylonitrile butadiene rubber for the piston and piston rod seals. The cylinder pistons are made of brass, the piston guide bush of sintered bronze.
The cylinder tubes are supplied anodised or bright, the end caps bright, painted or anodised, the piston rods bright or hard chromed (depending on model).
In the norelem online shop, pneumatic cylinders are offered in three different designs Pneumatic standard cylinder, Pneumatic compact cylinder and Pneumatic round cylinder.
The DIN ISO 15552 light design standard cylinder is available with a piston diameter of 32 to 80 mm and stroke lengths of 25 to 250 mm. Due to its optimised design, 20 percent of the material can be saved during production of this standard cylinder. The cylinder tube is made of anodised aluminium, the piston rod of hard chromed, high-carbon steel. The piston rod with male thread has adjustable pneumatic damping and can be supplemented with position sensors.
The DIN ISO 21287 compact cylinders from norelem can be supplied with male or female thread, piston diameters of 20 to 40 mm and stroke lengths of 10 to 50 mm. The DIN ISO 21287 compact cylinders are equipped with elastic damping on both ends and can be supplemented with position detection for proximity switches. The cylinder tube is made of anodised aluminium, the piston rod of stainless steel. The compact cylinder is particularly suitable for use in confined installation spaces. The pressure applied to the pneumatic cylinder responds promptly.
As by the compact cylinder, the DIN ISO 6432 round cylinder from norelem also has elastic damping on both ends and can be suplemented with positioning sensing for proximity switches. The round cylinder has piston diameters of 10 to 25 mm and stroke lengths of 10 to 200 mm, the material is stainless steel. The round cylinder is also characterised by standardised precision fit. Pneumatic round cylinders are ideal for applications with lighter loads or forces and can also be installed without fastening elements.
In the norelem online shop and THE BIG GREEN BOOK a distinction is made between pneumatic cylinders with single acting and double acting cylinders.
Has only one air port
Is operated purely with compressed air
Requires a spring to return to the start position
The pneumatic cylinder is moved out and in with compressed air
When retracting and advancing, the pneumatic cylinder can work at almost full power
