About the Airtac MIC Cushioned Mini Cylinder MIC40X15SU
Generating up to 879.6 N of push force at 0.7 MPa, this double-acting round-body mini cylinder handles heavy-duty actuation in compact spaces. The stainless-steel barrel and rod resist mild corrosion and washdown environments, while the U-type back cover provides a 90-degree mounting orientation for tight machinery layouts. A 1/4" port supplies the air, and the M12x1.25 male rod thread secures the load.
The defining feature of the MIC40X15SU is its adjustable air cushion at both ends. Unlike a fixed bumper, a needle valve lets you dial in the deceleration to absorb end-of-stroke shock at high speeds, protecting the load and reducing noise. For vertical applications, the 628.3 N push force at 0.5 MPa yields a safe working load of about 377 N, meaning it lifts roughly 32 kg with a 2:1 safety margin. The built-in -S magnet supports CMSG, DMSG, and EMSG sensors for position detection.

Where the Airtac MIC Cushioned Mini Cylinder MIC40X15SU Is Used
Short-Stroke Clamping
Ideal for securing heavy metal workpieces. The 15 mm stroke delivers rapid clamping with 879.6 N of force at 0.7 MPa, while the needle cushion softens the impact.
Package Diverting
Handles heavy product routing on conveyor lines. The stainless build survives washdown zones, and the 90-degree U cover fits tight transfer points.
Vertical Pressing
Pushes down with a safe working load of 377 N. The adjustable air cushion ensures smooth deceleration at the bottom of the stroke, protecting the assembly.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X15SU the Right Cylinder?
Choosing this 40 mm bore makes sense when you need substantial push power that smaller bores cannot provide, as there is no larger standard MIC size. If your application requires less force, stepping down to a 32 mm bore reduces the push force to 402.2 N at 0.5 MPa. The adjustable cushion is essential here for the 30-800 mm/s speed range, specifically when moving heavy loads, because it prevents harsh impacts at the 15 mm stroke end. Note that the cushion only decelerates the piston; it does not act as a brake. If you need to hold a load vertically during air loss, install an external rod lock or pilot-operated check valve. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion, and the -S magnet enables electronic or reed 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 0.15 – 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 MIC40X15SU FAQ
This 40 mm bore double-acting cylinder uses a 1/4" air port and a 16 mm piston rod. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum force of 128.1 kgf at 1.0 MPa.
No, the adjustable air cushion only decelerates the piston near the stroke end and does not act as a lock or brake. The piston will drift on air loss. For load holding, you need an external rod lock or pilot check valve. The -S magnet allows CMSG/DMSG/EMSG sensors for position confirmation.
