Airtac MIC Cushioned Mini Cylinder MIC20X70SCA
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC20X70SCA is a genuine double acting + cushion round-body mini air cylinder with a Ø20mm bore and 70mm 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 MIC20X70SCA
Dial in end-of-stroke deceleration with the AirTAC MIC20X70SCA, a stainless-steel round-body mini cylinder built for double-acting operation. Because it carries a variable air cushion at both ends, you can turn a needle valve to absorb high-speed shock, protecting your payload and lowering shop noise far better than a fixed bumper. The Ø20 mm bore uses a 1/8" port and an M8x1.25 male rod thread, dropping neatly into ISO 6432 mini-cylinder mounting interfaces.
At 0.5 MPa this size pushes 157 N and pulls 131.9 N, translating to a safe working load of roughly 94 N or a vertical lift of about 8 kg with a 2:1 margin. The stainless barrel and rod shrug off mild corrosion and washdown, while the -S suffix adds a piston magnet for CMSG, DMSG or EMSG position switches. A CA rear pivot cover equips the back for clevis mounting.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X70SCA Is Used
Package Diverting
Shifts small cartons at 30-800 mm/s onto adjacent belts, relying on the needle-set cushions to stop the 8 kg load gently without jarring the mechanism.
Film Sealing Head
Drives a heat seal bar down on packaging film, using the 157 N push force at 0.5 MPa while the stainless build resists incidental washdown.
Small Part Ejection
Kicks molded plastic parts out of a fixture, using the CA pivot mount to swing cleanly and the adjustable cushion to absorb the rapid return shock.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X70SCA the Right Cylinder?
If you need less force, stepping down to the MIC16 drops the 0.5 MPa push to 100.5 N; if your payload grows, the MIC25 raises it to 245.3 N. Choose this Ø20 bore when cycling at high speeds or moving enough mass that uncontrolled end-of-stroke impacts would damage the tooling. The adjustable cushions only decelerate the piston near the end of travel—they do not lock the rod. If gravity or air loss could let the load drift, fit an external rod lock or pilot check valve. Match your mounting using LB foot, FA flange, SDB pivot or TC trunnion brackets, and wire up CMSG/DMSG/EMSG sensors since the -S magnet is present.
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 MIC20X70SCA FAQ
This double-acting cylinder has a 1/8" port and an 8 mm piston rod. It pushes 157 N and pulls 131.9 N at 0.5 MPa, pushes 219.8 N and pulls 184.7 N at 0.7 MPa, and reaches a theoretical maximum of 32 kgf at 1.0 MPa.
Yes, the -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG switches. The adjustable air cushion only decelerates the piston near stroke end to reduce shock; it is not a brake. For holding a load vertically on air loss, install an external rod lock or pilot check valve.
