Airtac MIC Cushioned Mini Cylinder MIC25X550SCM
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC25X550SCM is a genuine double acting + cushion round-body mini air cylinder with a Ø25mm bore and 550mm 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 MIC25X550SCM
Delivering 245.3 N of push force at 0.5 MPa, this double-acting stainless steel round-body mini cylinder handles demanding 25 mm bore tasks. The 550 mm stroke is a non-standard, made-to-order length exceeding the 500 mm catalog maximum, built specifically for extended travel. A variable air cushion at both ends allows needle adjustment to decelerate high-speed loads smoothly, reducing shock and noise better than a fixed bumper.
The stainless barrel and rod resist mild corrosion and washdown environments. It uses the ISO 6432 mounting interface for standard brackets and features a CM round rear cover. Equipped with an -S piston magnet, it supports CMSG, DMSG, and EMSG sensors. With a 245.3 N push force, it provides a safe working load of roughly 147 N, lifting about 12.5 kg vertically with a 2:1 margin. The 1/8" port and M10x1.25 male rod thread complete the pneumatic setup.

Where the Airtac MIC Cushioned Mini Cylinder MIC25X550SCM Is Used
Extended Transfer Sorting
Pushes packages across wide conveyor diverter points using the 550 mm travel, relying on the adjustable cushion to stop the 245.3 N thrust smoothly without slamming.
Vertical Film Pulling
Lifts packaging film rolls weighing up to 12.5 kg vertically in form-fill-seal machines, where the stainless build resists washdown and the magnet tracks position.
Long-Stroke Component Gauging
Extends measuring probes into deep machined cavities, using the needle-set cushion to protect sensitive gauges from end-of-stroke impact at high cycling speeds.
Is the Airtac MIC Cushioned Mini Cylinder MIC25X550SCM the Right Cylinder?
When sizing this 25 mm bore unit, stepping down to the MIC20 drops the 0.5 MPa push force to 157.0 N, while stepping up to the MIC32 raises it to 402.2 N. Choose this non-standard 550 mm stroke only when the 500 mm maximum standard travel is insufficient for your machine layout. The adjustable air cushion is essential for high-speed or heavy moving loads, letting you dial in the end-of-stroke deceleration.
Remember that the air cushion only slows the piston near the end of travel; it is not a brake. If air pressure drops, the piston will drift, so install an external rod lock or pilot-operated check valve to hold a suspended load. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion. The included -S magnet enables position sensing with CMSG, DMSG, or EMSG 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 MIC25X550SCM FAQ
This 25 mm bore cylinder has a non-standard 550 mm stroke (exceeding the 500 mm max standard). It pushes 245.3 N and pulls 206.1 N at 0.5 MPa, pushes 343.4 N and pulls 288.5 N at 0.7 MPa, with a theoretical max of 50 kgf at 1.0 MPa. The air port is 1/8" and the male rod thread is M10x1.25.
No, the adjustable air cushion only decelerates the piston near stroke end to reduce shock; it is not a lock or brake. The piston will drift on air loss, so use an external rod lock for holding. The -S designation means it has a built-in piston magnet for CMSG, DMSG, or EMSG position switches.
