Norgren M/50 Series ISO Pneumatic Cylinder

Overview

The Norgren M/50 Series, marketed under the RA/192000/M part-number range, is an ISO 21287 compact double-acting pneumatic cylinder built for industrial automation, machine building, and valve actuation applications that need a compact, reliable linear drive. Constructed with an anodized aluminium profile barrel, pressure die-cast aluminium end covers, and a stainless steel piston rod, the M/50 Series is available in nine bore diameters from 20 mm to 125 mm, with standard strokes from 5 mm up to 500 mm depending on bore size. A magnetic piston is fitted as standard, allowing the M/50 range of reed and solid-state proximity switches to mount flush with the cylinder profile for reliable end-of-stroke and mid-stroke position sensing.

As the official authorized partner and exclusive regional representative for Norgren, Seven Star LLC proudly supplies the M/50 Series ISO pneumatic cylinder to manufacturing plants, packaging lines, and valve automation projects across Oman, Muscat, and the wider GCC. Every cylinder shipped through Seven Star LLC is genuine IMI Norgren product, backed by full technical documentation, factory warranty, and local application support tailored to the dusty, high-ambient-temperature conditions common across industrial sites in the Sultanate of Oman.

Operating Principle

The Norgren M/50 Series operates as a standard double-acting pneumatic cylinder: filtered, lubricated or non-lubricated compressed air enters through one of two ports (M5 thread on the smallest bores, up to G1/4 on the 125 mm bore) to drive the piston and its stainless steel rod outward, while air on the opposite side is exhausted; reversing the air supply retracts the rod. Buffer cushioning is built into both ends of the standard cylinder to decelerate the piston mechanically near the end of stroke, protecting the cylinder and connected load from impact damage at higher cycling speeds. Piston and rod sealing is handled by NBR piston seals and PUR rod seals, chosen specifically for low-friction operation and long service life across the -5°C to +80°C standard operating range.

Because the standard piston is magnetized, position-sensing switches from the M/50 accessory range can be clipped directly onto the cylinder’s external profile groove without any drilling or internal modification, and can be repositioned at any point along the stroke to signal intermediate positions as well as full extension and retraction. The practical result is a cylinder that gives machine builders and valve automation packagers accurate, tool-free position feedback alongside a compact, corrosion-resistant actuator body suited to continuous industrial duty.

Engineering Design of the Norgren M/50 Series

The Norgren M/50 Series profile barrel is anodized aluminium for corrosion resistance and low weight, while the end covers are pressure die-cast aluminium, giving the cylinder a rigid, dimensionally stable envelope that conforms to ISO 21287 mounting standards. This ISO compliance means the M/50 Series is dimensionally interchangeable with other manufacturers’ ISO-standard compact cylinders, simplifying spares management and machine retrofit projects. The cylinder is available with either a male or female piston rod thread (RA/192000/M and RA/192000/MX respectively), and Norgren offers an extensive range of mounting accessories — front and rear flanges, foot mounts, clevis mounts, trunnion mounts, and swivel eyes — conforming to ISO 15552 and VDMA 24562 standards, giving designers full flexibility in how the cylinder is fixed into a machine frame or valve linkage.

Beyond the standard configuration, the M/50 platform extends to variants including non-rotating piston rod guiding (N2/N4/N6), double-ended piston rod (JM), tandem cylinders for increased force output (TM), multi-position cylinders (SM), and a passive locking unit (L4) that mechanically holds the rod position on loss of air supply — a feature particularly relevant for fail-safe valve actuation duty. High-temperature variants rated to 150°C and stainless steel piston rod options (martensitic or austenitic) extend the cylinder’s suitability into washdown and elevated-temperature process environments.

Key Features

Specifying the Norgren M/50 Series ISO pneumatic cylinder gives machine builders and automation integrators a compact, standards-compliant linear actuator for demanding duty cycles:

• Conforms to ISO 21287 for dimensional interchangeability with other ISO-standard compact cylinders.
• Nine bore sizes from 20 mm to 125 mm cover thrust outputs from roughly 188N to over 7,300N at 6 bar.
• Magnetic piston as standard allows flush-mounted reed or solid-state position sensing switches without drilling.
• Anodized aluminium profile barrel and die-cast aluminium end covers resist corrosion in humid or coastal environments.
• Standard operating pressure range of 1 to 10 bar with an operating temperature range of -5°C to +80°C (high-temperature variant to 150°C).
• Broad mounting accessory range — flange, foot, clevis, trunnion, and swivel — conforming to ISO 15552 and VDMA 24562.
• Optional passive locking unit (L4) mechanically holds rod position on loss of air supply for fail-safe applications.
• Non-rotating rod guiding, tandem, and multi-position variants extend the platform into precision positioning and increased-force duty.

Industrial Applications

The Norgren M/50 Series the Norgren M/50 Series is widely used across manufacturing and packaging automation for clamping, indexing, lifting, and transfer duty, and is equally common as the linear drive element in pneumatically actuated valve linkages, damper drives, and machine guarding interlocks. Its compact ISO 21287 envelope and corrosion-resistant construction make it a practical choice for food and beverage processing lines, general industrial automation cells, and OEM machine building across Oman’s manufacturing and logistics sector, where reliable, low-maintenance linear actuation is essential to production uptime.

As the officially authorized partner for Norgren, Seven Star LLC distributes the Norgren M/50 Series pneumatic cylinder range across Oman and the GCC to OEMs, system integrators, and maintenance teams supporting manufacturing plants, packaging lines, and valve automation projects from Muscat through the Sohar and Salalah industrial and free zones.
