About the Airtac MIC Cushioned Mini Cylinder MIC20X70SCM
Soaking up high-speed end-of-stroke shock, the AirTAC MIC20X70SCM is a double-acting round-body mini cylinder built with a stainless-steel barrel and rod for mild washdown resistance. It conforms to the ISO 6432 mounting interface for Ø20 bores, dropping directly into standard mini brackets and clevises. The CM round rear cover dictates a clean, inline port orientation.
At 0.5 MPa it generates 157 N of push force and 131.9 N of pull, translating to a safe working load of roughly 94 N or a vertical lift of about 8 kg with a 2:1 margin. Unlike a fixed bumper, its needle-set variable air cushion at both ends lets you dial in deceleration to protect payloads. The integrated -S magnet enables position sensing with CMSG, DMSG or EMSG switches, and air connects via a 1/8" port.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X70SCM Is Used
Light Package Diverting
Uses the 157 N push force to push small parcels off a high-speed belt, relying on the adjustable air cushion to stop the 70 mm stroke without bouncing the load.
Small Part Ejection
Ejects molded components at rapid cycle rates; the needle-set cushion absorbs the end shock to protect delicate plastic parts from cracking.
Vertical Lowering Assist
Lifts or lowers an 8 kg fixture vertically, using the ISO 6432 standard mount and the dual-end cushion to prevent hard bottoming on descent.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X70SCM the Right Cylinder?
If you need less force, the Ø16 bore provides 100.5 N push at 0.5 MPa but lacks the adjustable cushion; stepping up to the Ø32 bore yields 402.2 N. The cushion on this Ø20 model is essential when cycling at high speeds between 30-800 mm/s with heavy loads, as it prevents impact damage. Remember the cushion only decelerates near the stroke end and acts as no brake; for holding a load on air loss, install an external rod lock or pilot check valve. Pair the -S magnet with CMSG/DMSG/EMSG sensors and mount using LB foot, FA flange, or TC trunnion hardware.
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 MIC20X70SCM FAQ
This 20 mm bore cylinder features an 8 mm piston rod with an M8x1.25 male thread and a 1/8" air port. It delivers 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 piston near stroke end and does not lock or hold position; you must add a pilot check valve or external rod lock to prevent drift on air loss.
