About the Airtac MIC Cushioned Mini Cylinder MIC20X250SCM
High-speed automation gets quieter with the AirTAC MIC20X250SCM, 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 end-of-stroke shock, protecting your payload far better than a fixed bumper. It conforms to the ISO 6432 mounting interface for Ø20 bores, dropping directly into standard mini brackets and clevises.
Delivering 157 N of push force and 131.9 N of pull at 0.5 MPa, this 250 mm stroke unit yields a safe working load of about 94 N, lifting roughly 8 kg vertically with a 2:1 safety margin. The CM round rear cover keeps ports neatly oriented, while the 1/8" port and M8x1.25 male rod thread simplify fittings. Because the -S suffix equips the piston with a magnet, you can mount CMSG, DMSG, or EMSG sensors for position detection.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X250SCM Is Used
Package Diverting
Uses the 157 N push force to deflect light cartons on a high-speed sorting line, relying on the adjustable air cushion to prevent harsh slams at the 250 mm stroke end.
Small Part Ejection
Ejects molded components from a press, where the stainless build resists shop moisture and the needle-set cushion protects fragile parts from impact damage.
Vertical Lift Gates
Raises an 8 kg access flap using the 0.5 MPa thrust, using the ISO 6432 standard mounting brackets to integrate seamlessly into existing conveyor frames.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X250SCM the Right Cylinder?
When sizing this 157 N @0.5 MPa unit, step down to the Ø16 bore if your load is under 100 N, or move up to the Ø25 bore (245 N @0.5 MPa) if you need more thrust. The adjustable air cushion is essential here: dial in the needle to decelerate heavy loads at high speeds up to 800 mm/s. Note that the cushion only slows the piston near the stroke end; it is not a brake. If the air supply drops, the rod will drift, so fit an external rod lock or pilot check valve to hold a suspended load.
Mounting flexibility comes from LB foot, FA flange, SDB pivot, and TC trunnion options alongside the CM back cover. The integrated -S magnet allows direct CMSG/DMSG/EMSG switch installation without modifying the cylinder.
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 MIC20X250SCM FAQ
This double-acting cylinder has a 20 mm bore, an 8 mm rod, and a 250 mm stroke. It generates 157 N push / 131.9 N pull at 0.5 MPa, and 219.8 N push / 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa. It features a 1/8" port, an M8x1.25 male rod thread, and operates at speeds of 30-800 mm/s.
No, the adjustable air cushion only decelerates the piston near the end of the stroke and does not act as a brake or lock. If air pressure is lost, the piston will drift. To maintain a vertical load safely, you must install an external rod lock or a pilot-operated check valve. The -S magnet allows CMSG/DMSG/EMSG sensors to verify position.
