About the Airtac MIC Cushioned Mini Cylinder MIC40X75SCM
Delivering 879.6 N of push force at 0.7 MPa, the AirTAC MIC40X75SCM is a robust round-body mini cylinder built for demanding automation. This double-acting actuator features a stainless-steel barrel and piston rod, offering reliable mild corrosion and washdown resistance without relying on a tie-rod or extruded profile frame. A 1/4" port supplies the air, driving a Ø16 mm rod with an M12x1.25 male thread.
The defining feature is the adjustable air cushion at both ends, allowing you to needle-set the deceleration to eliminate end-of-stroke shock at high cycling speeds. For practical sizing, it yields a safe working load of about 377 N, meaning it lifts roughly 32 kg vertically with a 2:1 safety margin. The -S suffix equips the piston with a magnet for CMSG, DMSG, or EMSG position switches.

Where the Airtac MIC Cushioned Mini Cylinder MIC40X75SCM Is Used
Heavy Package Diverting
Handles the kinetic energy of routing dense cartons on a high-speed sorting line, using the adjustable cushions to stop the 32 kg working load smoothly without slammimg.
Voluminous Bag Forming
Pushes heavy packaging materials into position on a vertical sealer, where the stainless construction survives washdowns and the 1/4" port delivers the volume needed for rapid cycling.
Pallet Component Pressing
Presses lightweight sub-assemblies into pallet bases, relying on the 879.6 N push force at 0.7 MPa to seat parts firmly while the needle valves prevent impact damage.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X75SCM the Right Cylinder?
When sizing this 40 mm bore actuator, compare it against the adjacent MIC32, which provides 402.2 N of push force at 0.5 MPa. If your application demands less energy, the 32 mm option is more efficient; however, the MIC40 is the largest available bore in this series, so for loads exceeding its capacity, you must look outside the MIC family. Choose this model specifically when moving heavier masses at high speeds, as the adjustable needle cushions are critical for smoothing the stroke end and protecting the payload.
Keep in mind the cushion only decelerates the piston near the end of travel; it does not function as a brake or lock. If your system loses air, the piston will drift, so you must integrate an external rod lock or pilot-operated check valve to hold a suspended load. The CM round end back cover dictates the rear mounting and port orientation, and you can utilize LB foot, FA flange, SDB pivot, or TC trunnion mounts to secure the body.
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 MIC40X75SCM FAQ
This 40 mm bore cylinder features a 1/4" air port and an M12x1.25 male rod thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, increasing to 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.
No, the adjustable air cushion only decelerates the piston near the stroke end and acts purely as a shock absorber, never as a brake. Because it is double-acting, the rod will drift if air is lost, requiring an external rod lock or pilot check valve for suspended loads. The -S magnet enables CMSG, DMSG, and EMSG sensors for position tracking.
