Airtac MIC Cushioned Mini Cylinder MIC25X550SCA
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC25X550SCA 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 MIC25X550SCA
High-speed strokes hit hard, but the AirTAC MIC25X550SCA uses a variable air cushion at both ends to bleed off that end-of-travel shock, protecting your payload. This double-acting stainless steel round-body mini cylinder pushes with 245.3 N and pulls with 206.1 N at 0.5 MPa. It features a 25 mm bore, a 550 mm stroke, and a built-in magnet for position sensing. The 550 mm stroke exceeds the 500 mm standard maximum for this bore, making it a non-standard, made-to-order configuration.
The stainless barrel and rod resist mild corrosion and washdown environments. Because it uses the ISO 6432 mounting interface, it drops directly into standard mini-cylinder brackets and clevises. With a 1/8" port and an M10x1.25 male rod thread, it generates a safe working load of roughly 147 N, lifting about 12.5 kg vertically with a 2:1 safety margin. The CA rear pivot cover allows direct clevis mounting.

Where the Airtac MIC Cushioned Mini Cylinder MIC25X550SCA Is Used
High-Speed Diverting
Uses the adjustable air cushion to smoothly halt a 12 kg package diverter at 800 mm/s without slamming the end caps, extending mechanical life on the line.
Washdown Sealing Press
The stainless construction survives damp packaging areas, pushing a sealing head with 245 N of force while the cushions absorb the rapid return impact.
Pivot Gate Actuation
The CA rear clevis mounts directly to a sorting gate, using the 550 mm stroke to fully open the lane while the ISO 6432 dimensions ensure easy bracket replacement.
Is the Airtac MIC Cushioned Mini Cylinder MIC25X550SCA the Right Cylinder?
If you need less force, the smaller MIC20 bore provides 157 N of push at 0.5 MPa, while stepping up to the larger MIC32 yields 402 N for heavier payloads. Choose this 25 mm bore when moving moderate masses at high speeds, as the needle-set air cushions prevent harsh end-stop banging. For vertical loads, remember the cushion only decelerates the stroke near the end and does not act as a brake; the piston will drift if air pressure drops, so add an external rod lock or pilot check valve for fail-safe holding.
The included -S magnet supports CMSG, DMSG, and EMSG switches for electronic or reed position sensing. You can mount this unit using LB foot brackets, FA flanges, SDB pivot blocks, or TC trunnions to suit your frame. The CA back cover provides a fixed rear clevis interface for pivoting articulation.
Quick checklist

- ✓ 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 MIC25X550SCA FAQ
This 25 mm bore cylinder features a 1/8" port and an M10x1.25 male rod thread. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, increasing to 343.4 N push and 288.5 N pull at 0.7 MPa. The theoretical maximum force is 50 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG sensors. However, the adjustable air cushion only decelerates the load near the stroke end and does not function as a lock or brake; the piston will drift on air loss, so you need an external rod lock or pilot check valve to hold a suspended load.
