About the Airtac MIC Cushioned Mini Cylinder MIC40X500CM
Tame high-speed end-of-stroke shock with the AirTAC MIC40X500CM, a double-acting round-body mini cylinder built for demanding 500 mm travel tasks. A variable air cushion at both ends lets you dial in the deceleration via a needle valve, quietly soaking up kinetic energy to protect your payload. The stainless-steel barrel and Ø16 mm rod shrug off mild corrosion and washdown environments, while the CM round rear cover provides a clean, compact mounting footprint.
Delivering serious muscle for a mini cylinder, this Ø40 mm bore unit pushes 628.3 N and pulls 527.8 N at 0.5 MPa, peaking at a theoretical 128.1 kgf at 1.0 MPa. With a safe working load around 377 N, it lifts about 32 kg vertically using a 2:1 safety margin. It features a 1/4" port and an M12x1.25 male rod thread. Note that this base SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors—specify the -S variant if you need position detection.

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 MIC40X500CM Is Used
Heavy Parcel Diverting
Drive high-speed routing arms on 500 mm strokes, relying on the adjustable cushion to stop 32 kg loads smoothly without slamming the end caps.
Vertical Lift Gates
Raise and lower access doors using the 628.3 N push force, benefiting from the stainless build in mildly humid dispatch areas.
Large Carton Forming
Actuate folding mechanisms for heavy packaging, using the 1/4" port for rapid fill and exhaust while the needle valve damps the impact.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X500CM the Right Cylinder?
As the largest bore in the MIC family, there is no larger standard cushioned size available; if you need less force, stepping down to the Ø32 bore drops the 0.5 MPa push force to 402.2 N. The adjustable air cushion is essential here because a 500 mm stroke at speeds up to 800 mm/s generates significant momentum that a fixed rubber bumper cannot safely absorb. Because this is a non-ISO-6432 round-body cylinder, ensure your mounting hardware matches the Ø40 form factor, utilizing LB foot, FA flange, SDB pivot, or TC trunnion brackets.
Remember that the air cushion only decelerates the piston near the stroke end—it does not function as a brake or lock. If your application must hold a vertical load when air pressure drops or a valve is centered, the piston will drift, requiring an external rod lock or pilot-operated check valve. Additionally, without the -S magnet option, this specific SKU cannot support magnetic sensing switches.
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 MIC40X500CM FAQ
This Ø40 mm cylinder uses a 1/4" port and an M12x1.25 male rod thread. 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, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You must select the -S variant for position sensing. The adjustable air cushion and stainless steel construction are still standard.
