About the Airtac MIC Cushioned Mini Cylinder MIC40X60SU
Delivering 879.6 N of push force at 0.7 MPa, this double-acting stainless steel round-body mini cylinder handles heavy-duty actuation. The Ø40 bore operates on a 1/4" port with a robust Ø16 piston rod and M12x1.25 male thread. A built-in magnet (-S) enables position sensing with CMSG, DMSG, or EMSG switches. The U-style back cover provides a 90-degree rear mounting orientation for compact installations.
Twin adjustable air cushions at both stroke ends let you needle-set the deceleration to absorb end-of-stroke shock at high cycling speeds. This protects machinery and reduces noise far better than a fixed bumper. For vertical applications, it safely lifts about 32 kg with a 2:1 margin. Note that the cushion only decelerates the load; it does not function as a brake, so an external rod lock or pilot check valve is required to hold position on air loss.

Where the Airtac MIC Cushioned Mini Cylinder MIC40X60SU Is Used
Heavy Package Diversion
Uses the 879.6 N push force at 0.7 MPa to push heavy cartons off a high-speed belt, relying on the adjustable air cushion to silently stop the 60 mm stroke without slamming.
Vertical Press Down
Lifts or presses loads up to 32 kg safely with a 2:1 margin, where the needle-set cushion decelerates the heavy descent at the bottom of the stroke to protect the tooling.
Carton Sealing Head
Drives a sealing jaw in a washdown packaging line, utilizing the stainless steel construction and 1/4" port for reliable high-cycle performance under moist conditions.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X60SU the Right Cylinder?
When sizing this 60 mm stroke unit, step down to the MIC32 bore if your load is lighter, which provides 402.2 N push at 0.5 MPa. There is no larger standard MIC bore above Ø40, making this the top choice for maximum thrust. The adjustable air cushion is essential here when driving heavy loads at high speeds, as the 628.3 N push force at 0.5 MPa generates significant end-of-stroke inertia. The stainless barrel and rod resist mild corrosion, making it suitable for washdown environments.
Because the piston drifts when air pressure is lost, never rely on the cushion for load holding; add a pilot-operated check valve for vertical safety. The -S magnet allows seamless integration with CMSG, DMSG, and EMSG sensors. You can mount this cylinder using LB foot, FA flange, SDB pivot, or TC trunnion hardware, while the U back cover handles the 90-degree rear setup.
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 0.15 – 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 MIC Cushioned Mini Cylinder MIC40X60SU FAQ
This double-acting cylinder has a Ø40 bore, Ø16 rod, and 1/4" port. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, or 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum force is 128.1 kgf at 1.0 MPa, and it operates at speeds of 30-800 mm/s.
The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors. The adjustable air cushion only decelerates the load near the stroke end; it is not a brake. The piston will drift on air loss, so you must use an external rod lock or pilot check valve to hold a vertical load.
