About the Airtac MIC Cushioned Mini Cylinder MIC40X65SU
Delivering serious thrust for a compact unit, the AirTAC MIC40X65SU is a 40mm bore double-acting round-body mini cylinder built with a stainless-steel barrel and rod. It pushes with 628.3N and pulls with 527.8N at 0.5MPa, peaking at a theoretical 128.1kgf at 1.0MPa. The stainless construction resists mild corrosion and washdown environments. Featuring a 1/4" port and an M12x1.25 male rod thread, it handles strokes up to 500mm at speeds of 30-800mm/s.
Unlike basic bumper models, this variant features an adjustable air cushion at both ends. By turning a needle valve, you dial in the deceleration to absorb end-of-stroke shock at high speeds, protecting your payload and reducing noise. The built-in magnet (-S) supports CMSG, DMSG, and EMSG position switches, while the U-style back cover provides a 90-degree mounting orientation. For practical sizing, expect a safe working load around 377N, lifting about 32kg vertically with a 2:1 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 MIC40X65SU Is Used
Package Diverting
Handles robust 32kg cartons at high cycle rates on a sorting line, relying on the adjustable cushions to prevent harsh end-of-stroke impacts.
Press Ejection
Pushes finished metal parts out of a light press using 628.3N of thrust, where the washdown-capable stainless rod resists cutting fluid mist.
Pallet Stopping
Acts as a heavy-duty stop for incoming pallets, using the 1/4" ported 40mm bore to generate high stopping force without bouncing the load.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X65SU the Right Cylinder?
If you need less force, the smaller Ø32 bore offers 402.2N push at 0.5MPa; since Ø40 is the largest available MIC size, stepping up requires a different cylinder family entirely. Choose this 65mm stroke model when moving heavier loads at high velocity, as the adjustable end cushions are essential for preventing impact damage. Note that the air cushion only decelerates the piston near the stroke end and does not function as a brake. The cylinder will drift if air pressure drops, so add an external rod lock or pilot check valve if you must hold a suspended load. Pair the -S magnet with CMSG, DMSG, or EMSG sensors for switching, and utilize LB, FA, SDB, or TC mounts alongside the U back cover for your installation.
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 MIC40X65SU FAQ
This 40mm bore double-acting cylinder uses a 1/4" port and an M12x1.25 male rod thread. It generates 628.3N push and 527.8N pull at 0.5MPa, 879.6N push and 738.9N pull at 0.7MPa, with a theoretical maximum of 128.1kgf at 1.0MPa.
The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors. It cannot hold a load on air loss; the piston will drift, and the adjustable air cushion only decelerates near stroke end rather than locking the rod. Use a pilot check valve for holding.
