About the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI20X60SR
Delivering 119.5 N of push force at 0.5 MPa (182.3 N at 0.7 MPa), this AirTAC round-body mini cylinder uses compressed air to extend and an internal mechanical spring to retract. Because it is a single-acting PUSH type, you only need to plumb one 1/8" air line, which cuts piping costs and simplifies valve selection. The return spring acts as a fail-safe, driving the rod back to its retracted rest state if air pressure drops.
Built with a stainless-steel barrel and piston rod, the riveted construction resists mild corrosion and washdown environments. It conforms to the ISO 6432 mounting interface for easy bracket interchangeability. The -S suffix denotes a built-in piston magnet for position sensing using CMSG, DMSG, or EMSG switches. For sizing context, its safe working load is roughly 72 N, allowing it to clamp or vertically lift about 6.1 kg with a 2:1 safety margin. The R back cover provides an axial port orientation for compact installations.

Where the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI20X60SR Is Used
Spring-Return Clamping
Provides 119.5 N of push force to secure light metal workpieces during machining, automatically releasing to the retracted rest position on air loss.
Package Diverter Gate
Extends 60 mm to deflect cartons on a conveyor line, using the internal spring to reliably pull the gate back and avoid jamming when air is cut.
Vertical Pin Stop
Acts as a fail-safe pin stop for totes, lifting loads up to 6.1 kg with a 2:1 margin, and safely retracting out of the way if system pressure drops.
Is the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI20X60SR the Right Cylinder?
When sizing by PUSH force, this Ø20 bore provides 119.5 N at 0.5 MPa. If you need less force, step down to the Ø16 bore which outputs 74.9 N; if you require more, step up to the Ø25 bore delivering 190.3 N. Remember that this single-acting design requires at least 0.2 MPa of input pressure to overcome the return spring before the rod will extend. The 60 mm stroke sits safely within the 80 mm standard travel limit for this bore. Select the -S magnet option if you need to mount CMSG, DMSG, or EMSG sensors, and pair it with LB, FA, SDB, or TC mounts for your application.
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 MSI20X60SR FAQ
It generates 119.5 N of push force at 0.5 MPa and 182.3 N at 0.7 MPa. Because it is single-acting with a return spring, it requires a minimum of 0.2 MPa to overcome the spring and extend; when air is released, the spring retracts the rod.
The -S indicates a built-in piston magnet for use with CMSG, DMSG, or EMSG position sensors. As a single-acting PUSH cylinder, it only needs one 1/8" air line to extend, saving piping and simplifying valves, while the stainless steel build resists mild corrosion.
