About the Airtac MIC Cushioned Mini Cylinder MIC40X225SCM
Delivering 879.6 N of push force at 0.7 MPa, the AirTAC MIC40X225SCM is a robust 40 mm bore double-acting round-body mini cylinder built for demanding motion tasks. It features a stainless-steel barrel and piston rod that resist mild corrosion and washdown environments. A 1/4" port supplies the air, driving an M12x1.25 male rod thread. Unlike basic bumper models, this variant uses a needle-set variable air cushion at both ends to decelerate heavy loads smoothly at high speeds, cutting shock and noise.
In practical terms, this cylinder handles a safe working load of roughly 377 N, which means it can lift about 32 kg vertically with a 2:1 safety margin. The 225 mm stroke falls within the 500 mm standard limit for this bore. Because it lacks a locking mechanism, the piston will drift if air pressure drops, so you should pair it with an external rod lock or pilot check valve if you need to hold a load securely. The included -S magnet supports CMSG, DMSG, and EMSG position switches.

Where the Airtac MIC Cushioned Mini Cylinder MIC40X225SCM Is Used
High-Speed Carton Diverting
Uses the 879.6 N push force at 0.7 MPa to push heavy parcels across sorting lanes, relying on the adjustable air cushion to prevent harsh end-of-stroke impacts during rapid cycling.
Vertical Film Roll Lifting
Lifts packaging film rolls up to 32 kg vertically with a 2:1 safety margin, where the stainless-steel construction holds up well in humid or washdown packaging areas.
Heavy Component Seating
Presses mechanical components into housings over the 225 mm stroke, using the needle-set cushion to gently decelerate the 16 mm rod before it reaches the bottom of the stroke.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X225SCM the Right Cylinder?
When sizing this 40 mm bore unit, consider stepping down to the MIC32 (563.0 N push at 0.5 MPa) if your load is lighter, as there is no larger standard MIC bore available for higher force demands. The adjustable air cushion is essential here for high-speed cycles or heavy 225 mm strokes, letting you tune the end-of-travel deceleration to protect your payload. Remember that the cushion only slows the piston near the end of the stroke; it does not function as a brake.
For mounting, the CM round end cover dictates the rear port orientation and body style. You can adapt the cylinder using LB foot, FA flange, SDB pivot, or TC trunnion brackets. Position sensing requires the built-in -S magnet to work with CMSG, DMSG, or EMSG switches; a SKU without the S suffix cannot take a sensor.
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 MIC40X225SCM FAQ
This 40 mm bore double-acting cylinder has 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, 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 brake or lock. If air pressure is lost, the piston will drift, so you should use an external rod lock or pilot-operated check valve for position holding. The -S magnet allows CMSG, DMSG, and EMSG sensors to track the piston position.
