Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI20X60U
The AirTAC Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI20X60U is a genuine single acting, push (spring return) round-body mini air cylinder with a Ø20mm bore and 60mm 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 MSI20X60U
Generating 119.5 N of push at 0.5 MPa, this AirTAC round-body mini cylinder uses compressed air to extend and an internal spring to retract. It is a single-acting PUSH type, needing just one 1/8" air line to operate. The stainless steel barrel and rod resist mild washdown corrosion. Because the return spring constantly pulls the rod back, the cylinder fails safe to the retracted position if air pressure drops.
With a 60 mm stroke, the rod travels within the standard 80 mm limit for this bore. For sizing, the effective safe working load is roughly 72 N, or about 6.1 kg of vertical lift with a 2:1 margin. The U-style back cover provides a 90-degree port and mounting orientation for compact installations. This base SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI20X60U Is Used
Part Ejection
Uses its 119.5 N push stroke to positively eject machined parts from a fixture, with the spring safely retracting the rod on air loss.
Flow Gating
Acts as a spring-return diverter gate on a conveyor line, extending to block flow and relying on the internal spring to open the path.
Carton Stopping
Provides a firm pin-stop for light packaging carts, applying about 72 N of safe working force to halt movement without damage.
Is the Airtac MSI Single Acting Stainless Steel Mini Cylinder MSI20X60U the Right Cylinder?
When sizing by push force, this Ø20 bore yields 119.5 N at 0.5 MPa. If less force is needed, stepping down to the Ø16 bore provides 74.9 N. For heavier ejection tasks, moving up to the Ø25 bore offers 190.3 N. Remember that at least 0.2 MPa of air pressure is required to overcome the internal spring; below that, the rod will not extend. The 60 mm stroke fits well within the 80 mm standard single-acting travel limit, making it a stock-friendly choice. Mount this ISO 6432 interface cylinder using standard LB foot brackets, FA flanges, or TC trunnions.
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 MSI20X60U FAQ
It delivers a push force of 119.5 N at 0.5 MPa and 182.3 N at 0.7 MPa. You must supply at least 0.2 MPa to overcome the internal spring; below that, the rod stays retracted. The return stroke is spring-only.
No, this specific SKU does not have a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. It features a stainless build and fixed TPU bumper pads.
