Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI16X5SU
The AirTAC Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI16X5SU is a genuine single acting, push (spring return) round-body mini air cylinder with a Ø16mm bore and 5mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI16X5SU
Delivering 74.9 N of net push force at 0.5 MPa, this AirTAC stainless-steel mini cylinder uses compressed air to extend the rod and an internal spring to retract it. Because it is a single-acting PUSH type, you only need one air line connected to its 1/8" port, which saves on plumbing and valve complexity. If air pressure drops, the return spring automatically drives the rod back to its safely retracted rest position.
The Ø16 mm round-body construction features a stainless barrel and piston rod that resist mild corrosion and washdown environments. It conforms to the ISO 6432 mounting interface, dropping directly into standard mini brackets and clevises. For practical sizing, expect a safe working load of about 45 N, or a vertical lift capacity of roughly 3.8 kg when applying a 2:1 safety margin. This specific SKU includes a built-in piston magnet (-S) for CMSG, DMSG, or EMSG position sensors, and features a U-style 90-degree rear cover for port and mounting orientation.

Where the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI16X5SU Is Used
Short-Stroke Clamping
Ideal for holding light workpieces in a fixture, using its 74.9 N push force to secure parts while machining or assembly takes place.
Parts Ejector
Mounts via its ISO 6432 interface to push small finished components off a conveyor line, with the spring ensuring the pin retracts clear on air loss.
Gating Mechanism
Uses the 5 mm stroke to actuate a short diverter gate or stopper pin, relying on the fail-safe retract to clear the path when the air supply is removed.
Is the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI16X5SU the Right Cylinder?
When sizing by PUSH force, this 16 mm bore provides 74.9 N at 0.5 MPa. If your application requires less force, step down to the Ø12 bore which provides 44.0 N; if you need more, step up to the Ø20 bore which yields 119.5 N. Remember that the cylinder requires at least 0.2 MPa of input pressure to overcome the internal return spring—below that threshold, the rod will not extend. The 5 mm stroke is well within the 80 mm standard spring-limited travel for this bore size. Combine the U back cover with LB foot, FA flange, SDB pivot-block, or TC trunnion mounts to suit your layout, and utilize the -S magnet variant for switch integration.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.2 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI16X5SU FAQ
This single-acting push cylinder delivers 74.9 N of force at 0.5 MPa and 115.1 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the internal return spring. When air is released, the spring drives the rod back to its normally retracted rest position.
Yes, because this is the -S variant, it features a built-in piston magnet designed to work with CMSG, DMSG, and EMSG reed or electronic switches. A standard SKU without the S designation cannot take a sensor.
