Airtac MIC Cushioned Mini Cylinder MIC25X120SU
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC25X120SU is a genuine double acting + cushion round-body mini air cylinder with a Ø25mm bore and 120mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MIC Cushioned Mini Cylinder MIC25X120SU
Dial in end-of-stroke deceleration with the AirTAC MIC25X120SU, a double-acting round-body mini cylinder built with a stainless-steel barrel and rod for mild washdown resistance. A needle-set variable air cushion at both ends absorbs high-speed shock, protecting your payload far better than a fixed rubber bumper. It conforms to the ISO 6432 mounting interface for Ø25 bores, dropping directly into standard mini-cylinder brackets and clevises.
This 25 mm bore generates 245.3 N of push force and 206.1 N of pull at 0.5 MPa, peaking at a 50 kgf theoretical maximum at 1.0 MPa. The 120 mm stroke operates at 30-800 mm/s, fed by a 1/8" port and a Ø10 mm rod with an M10x1.25 male thread. For sizing, this translates to a safe working load of about 147 N, lifting roughly 12.5 kg vertically with a 2:1 margin. The U-style rear cover provides a 90-degree mounting orientation, and the built-in -S magnet supports CMSG, DMSG, and EMSG position switches.

Where the Airtac MIC Cushioned Mini Cylinder MIC25X120SU Is Used
Package Diverting
Handles lightweight carton routing at high cycle rates where the adjustable air cushion prevents harsh slams during 120 mm travel.
Film Sealing Press
Provides the 245.3 N push force needed to hold sealing jaws closed, while the stainless build resists occasional washdown spray.
Component Sorting
Uses the 12.5 kg vertical lift capacity to push selected parts out of a queue, relying on the ISO 6432 dimensions for easy bracket swaps.
Is the Airtac MIC Cushioned Mini Cylinder MIC25X120SU the Right Cylinder?
When sizing this unit, compare it against the adjacent bores: stepping down to the MIC20 drops your 0.5 MPa push force to 157 N, while stepping up to the MIC32 raises it to 402 N. Choose this 25 mm bore when your payload sits right in that 147 N safe-working-load window and you need the adjustable cushion to tame fast 30-800 mm/s cycling. The cushion needle only decelerates the piston near the stroke ends to reduce impact noise; it does not function as a brake.
Because a standard double-acting cylinder drifts when air pressure drops or the valve centers, you must add an external rod lock or a pilot-operated check valve if the load needs to be held in place vertically. For mounting flexibility beyond the U back cover, you can utilize LB foot, FA flange, SDB pivot, or TC trunnion hardware. Position sensing is fully enabled here via the -S magnet, allowing seamless CMSG, DMSG, or EMSG switch integration.
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 MIC25X120SU FAQ
This 25 mm bore cylinder features a 1/8" port and an M10x1.25 male rod thread. At 0.5 MPa it pushes with 245.3 N and pulls with 206.1 N. At 0.7 MPa the push increases to 343.4 N and the pull to 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
No, the adjustable air cushion only decelerates the piston near the end of stroke to reduce shock; it is not a brake. The cylinder will drift on air loss, so you need a pilot check valve or external rod lock to hold a load. The -S designation means it has a built-in piston magnet for mounting CMSG, DMSG, or EMSG position sensors.
