About the Airtac MIC Cushioned Mini Cylinder MIC40X25SCM
Delivering robust linear motion, the MIC40X25SCM is a double-acting round-body mini cylinder built with a stainless-steel barrel and rod to withstand mild washdown and corrosion. A 1/4" port feeds the 16mm piston rod, while the CM round rear cover provides a clean mounting footprint for this non-ISO-6432 40mm bore unit.
Twin adjustable air cushions at both stroke ends let you dial in needle valves to decelerate heavy loads smoothly at high speeds, eliminating the harsh impact of a fixed bumper. Generating 628.3N of push force at 0.5MPa, it yields a safe working load of roughly 377N, capable of lifting about 32kg vertically with a 2:1 safety margin.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G. Note: the Ø40 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MIC Cushioned Mini Cylinder MIC40X25SCM Is Used
Package Diverting
Handles 30kg cartons at high cycle rates on a sorting line, relying on the needle-set cushions to prevent end-of-stroke slamming.
Pallet Lift Stops
Acts as a heavy-duty physical stop for pallets, using its 628.3N push force at 0.5MPa to halt movement without bouncing.
Press Ejection
Ejects formed parts from a mild-washdown machining cell, where the stainless build resists coolant mist and the cushions soften rapid retraction.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X25SCM the Right Cylinder?
When sizing this 40mm bore, dropping down to a MIC32X50 reduces the push force to 402.2N at 0.5MPa, while no larger MIC bore exists for heavier demands. The adjustable cushions are essential if you cycle near the 800mm/s maximum or move substantial masses, as they only decelerate the piston near stroke end without acting as a lock. Because the piston drifts on air loss, add an external rod lock or pilot check valve for suspended loads. The -S suffix equips this CM-cover unit with a piston magnet for CMSG, DMSG, or EMSG sensors, and you can pair it with LB, FA, SDB, or TC mounts.
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 MIC40X25SCM FAQ
This 40mm bore double-acting cylinder uses a 1/4" port and a 16mm rod with an M12x1.25 thread. It pushes 628.3N and pulls 527.8N at 0.5MPa, pushes 879.6N and pulls 738.9N at 0.7MPa, and reaches a theoretical maximum of 128.1kgf at 1.0MPa.
The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG position switches. Instead of a fixed bumper, it features adjustable air cushions at both ends that you tune with a needle to decelerate the load near stroke end, which reduces shock but does not lock the rod.
