Norgren PRA/802000/M ISOLine ISO 15552 Pneumatic Cylinder
Overview
The Norgren PRA/802000/M is the profile barrel version of the Norgren ISOLine range, a double-acting pneumatic cylinder built to ISO 15552. It is made in bore diameters of 32, 40, 50, 63, 80, 100 and 125 mm. The same datasheet covers the round barrel RA/802000/M (32 to 125 mm) and the larger RA/8000/M (160 to 320 mm). Standard strokes run from 25 mm to 500 mm, and non-standard strokes from 5 mm up to 2800 mm are listed for bores of 50 to 125 mm. The piston is magnetic as standard, so Norgren M/50 magnetically operated switches can be fitted in the barrel profile for position sensing. M/50 is the switch, not the cylinder.
Seven Star LLC, an industrial supplier in Muscat, sources the Norgren PRA/802000/M ISOLine cylinder on request for manufacturing plants, packaging lines and machine builders in Oman and the wider GCC. Lead time is confirmed at quotation.
Operating Principle
The Norgren PRA/802000/M is a double-acting cylinder. Compressed air, filtered and either lubricated or non-lubricated, enters one port and moves the piston and rod outward while the opposite chamber exhausts. Reversing the supply retracts the rod.
The cylinder has adjustable end cushioning. Norgren fits its Adaptive Cushioning System (ACS), which cushions automatically over a wide range of general applications as delivered. Manual adjustment with the cushion screw remains possible for extreme applications. The magnet in the piston operates the switches fitted on the outside of the barrel, so the switch position can be set anywhere along the stroke without opening the cylinder.
Engineering Design of the Norgren PRA/802000/M
The barrel of the Norgren PRA/802000/M is anodised aluminium and the end covers are pressure die-cast aluminium. The standard piston rod is martensitic stainless steel. Piston seals and piston rod seals are PUR, and O-rings are NBR. Mounting dimensions follow ISO 15552. The piston rod is available with a male thread (PRA/802000/M) or a female thread (PRA/802000/MX).
The datasheet lists a wide set of variants on the same base cylinder: double-ended piston rod (JM), extended piston rod (MU), piston rod bellows (MG), no cushioning (MW), low friction (X2), special wiper seal for dirty conditions (W2), non-rotating piston rod (N2, 32 to 100 mm), four-position cylinder (MT) and a passive locking unit (L4) that holds the rod by spring force when its signal is removed. Low temperature (L), high temperature (T) and hydraulic (H) versions are also listed, together with piston rods in austenitic stainless steel or hard chromium plated steel. Mountings include front and rear flanges, foot mounting, rear clevis, piston rod clevis, detachable and centre trunnions, and swivel hinge.
Key Features
The main points of the Norgren PRA/802000/M ISOLine ISO 15552 pneumatic cylinder, taken from the Norgren datasheet:
- Conforms to ISO 15552, with profile barrel bores of 32, 40, 50, 63, 80, 100 and 125 mm.
- Theoretical thrust on the outstroke at 6 bar from 482 N (32 mm bore) to 7,363 N (125 mm bore).
- Magnetic piston as standard. M/50 switches can be mounted flush with the profile.
- Adaptive Cushioning System (ACS) with adjustable cushioning.
- Operating pressure of 1 to 12 bar for the profile barrel cylinder.
- Standard operating temperature of -20°C to +80°C for 32 to 125 mm bores. High temperature version up to +150°C and low temperature version down to -40°C.
- Anodised aluminium barrel, die-cast aluminium end covers, martensitic stainless steel piston rod, PUR seals.
- Variants with locking unit, non-rotating rod, double-ended rod, bellows, low friction and four positions.
Industrial Applications
The Norgren PRA/802000/M is a general purpose ISO cylinder for industrial automation. Typical duties are clamping, lifting, pushing, indexing and transfer on production and packaging machines, as well as linear drives for dampers, gates and guards. Norgren also lists the ISOLine range for food and beverage, automotive and rail use, with rail cylinders tested for shock and vibration to EN 61373.
Because ISO 15552 fixes the mounting dimensions, the cylinder can replace other ISO 15552 cylinders of the same bore and stroke in existing machines. Seven Star LLC can quote the cylinder together with the matching mountings and M/50 switches for projects in Muscat, Sohar, Salalah and elsewhere in the GCC. Items are supplied on request, lead time confirmed at quotation.

Norgren product families on this page
Air preparation is represented by the Excelon line, here the B74G-6AK-AD1-RMN filter regulator with 3/4 inch ports. Among directional valves the page lists the V51B517A-A2000, a 5/2 way pneumatic solenoid valve, and the Herion 2636 (26360 series) solenoid valve; Herion is an older name that still appears on many nameplates in process plants. Also listed are the 85750 series, a 2/2-way solenoid valve used for shut-off duty, and the M/50 series, which in the Norgren catalog is the magnetically operated switch that mounts on a cylinder to signal piston position.Where Norgren components are used
Filter regulators condition instrument air for control valve positioners and on-off valve actuators. Solenoid valves of the Herion type pilot pneumatic actuators on shutdown and process valves in oil and gas, chemical and power plants. The V-series valves and cylinders belong to packaging machines, material handling and general factory automation, in the GCC as anywhere else.Ordering Norgren parts: what we need
Norgren part numbers are long and every character counts. In a code such as B74G-6AK-AD1-RMN the blocks set the port size and thread, the drain type, the filter element, the bowl and the regulator spring. Send the complete number, or a photo of the label. For solenoid valves add the coil voltage and frequency, the port thread, the hazardous area protection required and the ambient temperature. For cylinders give the bore, stroke and mounting style, and for cylinder switches the full M/50 code with its cable length.Browse NORGREN products by category: Solenoid Valve, Regulators, Valve Actuator.
