About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X65SCM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles robust actuation tasks. The Ø20 mm bore operates on a 1/8 inch air port, and the 65 mm stroke falls well within the 500 mm standard limit. Its riveted stainless barrel and rod shrug off mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Fixed TPU bumper pads absorb the impact at stroke extremes without adding bulk.
Because this SKU includes a built-in magnet, it supports CMSG, DMSG, and EMSG position switches for closed-loop control. For practical sizing, plan for a safe working load of roughly 94 N, which means it can comfortably lift an 8 kg part vertically with a 2:1 safety margin. The rear CM round cover provides a clean, compact profile for tight machine cells.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X65SCM Is Used
Package Deflector
Pushes light cardboard cartons on a packaging line using its 157 N thrust and 65 mm travel.
Textile Loom Guide
Shifts a yarn guide arm in humid textile facilities where the stainless rod resists mild corrosion.
Bin Gate Actuator
Opens and closes small hopper gates for granular materials, relying on the CM round cover for a flush rear mount.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X65SCM the Right Cylinder?
When sizing this 20 mm bore, stepping down to a 16 mm variant drops the push force to 100.5 N, while moving up to a 25 mm bore increases it to 245.3 N at 0.5 MPa. This model uses the ISO 6432 mini-cylinder mounting interface, so it drops directly into standard brackets and clevises without custom hardware. You can pair it with LB foot, FA flange, SDB pivot, or TC trunnion mounts.
Remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centered; the TPU bumpers only soften the end of travel and will not lock the rod. To suspend a load safely, install an external rod lock or a pilot-operated check valve. For high-speed cycles that need end-deceleration tuning, consider the MIC variable cushion variant instead.
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 MI16-20 Stainless Steel Mini Cylinder MI20X65SCM FAQ
This 20 mm bore cylinder features a 1/8 inch air 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.
Yes, the -S suffix indicates a built-in piston magnet compatible with CMSG, DMSG, and EMSG reed or electronic switches. For impact absorption, it relies on fixed TPU bumper pads that decelerate the piston at stroke ends; it does not have an adjustable air cushion.
