About the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI16X50SR
Delivering a net push of 74.9 N at 0.5 MPa, this AirTAC round-body mini cylinder uses compressed air to extend and an internal mechanical spring to retract. The stainless steel barrel and Ø6 mm piston rod resist mild corrosion and washdown environments, while the 1/8" port provides ample flow. Because it is single-acting, you only need one air line, which simplifies plumbing and saves energy. The listed force is already net of the return spring.
This model includes an R axial-in rear cover and a built-in piston magnet (-S) for position sensing. For sizing, a safe working load is roughly 45 N, or it can vertically lift about 3.8 kg with a 2:1 safety margin. It conforms to the ISO 6432 mounting interface for easy bracket integration. The fixed TPU bumper pads soften the stroke end without locking the load.

Where the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI16X50SR Is Used
Light-Duty Clamping
Provides a reliable 74.9 N push to hold light workpieces in place during machining, releasing automatically to the retracted rest position when air is removed.
Package Ejector
Uses its 50 mm stroke to push small cartons off a conveyor line, relying on the internal spring to safely retract the pin if compressed air is lost.
Part Diverter Gate
Actuates a lightweight routing gate on a production track, with a safe working load of roughly 45 N ensuring consistent, repetitive diverting without overshooting.
Is the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI16X50SR the Right Cylinder?
When sizing by push force, this 16 mm bore yields 74.9 N at 0.5 MPa. If you need less force, step down to the Ø12 bore which provides 44.0 N; if your application requires more, step up to the Ø20 bore which outputs 119.5 N. Remember that the spring requires at least 0.2 MPa of supply pressure to overcome it and extend the rod.
The 50 mm stroke is a standard spring-limited travel length for this bore size. Since this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG sensors for end-of-stroke confirmation. You can pair it with LB foot brackets, FA flanges, or TC trunnions based on your machine geometry.
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 MSI16X50SR FAQ
It delivers a net push force of 74.9 N at 0.5 MPa and 115.1 N at 0.7 MPa. It requires a minimum of 0.2 MPa to overcome the internal spring and extend; when air is released, the spring drives the rod back to the retracted rest position.
Yes, because this SKU features the -S magnet, you can mount CMSG, DMSG, or EMSG switches directly to the stainless body. It is a single-acting push cylinder, so it only generates pneumatic force on the extension stroke.
