About the Airtac MIC Cushioned Mini Cylinder MIC20X400SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles long 400 mm strokes with precision. The Ø20 mm bore uses a 1/8 inch port and an M8x1.25 male rod thread. An integrated piston magnet (-S) enables position sensing with CMSG, DMSG, or EMSG switches. The CA rear cover supplies a pivot clevis for articulated mounting.
Twin adjustable air cushions at both stroke ends let you dial in needle valves to decelerate heavy loads smoothly, cutting shock and noise at high cycling speeds. This stainless build resists mild corrosion and washdown environments. Based on the 0.5 MPa push rating, it achieves a safe working load of roughly 94 N and lifts about 8 kg vertically with a 2:1 safety margin. It conforms to the ISO 6432 mounting interface for standard mini-cylinder brackets.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X400SCA Is Used
High-Speed Diverters
Cushions absorb the impact of routing small packages along a 400 mm stroke at high cycle rates without slamming.
Film Roll Feeding
The stainless round body withstands light washdown while the CA clevis pivots to feed packaging materials smoothly.
Vertical Lift Gates
Provides a safe 8 kg vertical lift margin, using the adjustable cushion to ease the gate into the closed position.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X400SCA the Right Cylinder?
When sizing this 157 N push unit, dropping to the smaller Ø16 bore yields 100.5 N, while stepping up to the Ø25 provides 245.3 N at the same 0.5 MPa. The adjustable cushions are essential if you drive the full 400 mm stroke near the 800 mm/s maximum speed, as they absorb kinetic energy. For vertical loads, remember the cushion only decelerates near the end of travel and acts as neither a lock nor a brake; the piston will drift on air loss. Fit an external pilot check valve or rod lock to hold position.
The CA pivot back cover suits swinging linkages, and you can pair the built-in magnet (-S) with CMSG, DMSG, or EMSG sensors for end-of-stroke confirmation.
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 MIC20X400SCA FAQ
This Ø20 mm bore cylinder features a 1/8 inch port and an M8x1.25 male rod thread. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
The -S suffix denotes a built-in piston magnet for CMSG, DMSG, or EMSG switches. The adjustable air cushion only decelerates the load near stroke end; it is not a brake, so you must add a pilot check valve or rod lock to prevent drift on air loss.
