About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100SU
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 100 mm travel requirement with ease. The Ø20 mm bore operates on a 1/8 inch port and features an M8x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted-steel alternatives in damp or washdown environments. The riveted construction keeps the body compact, while fixed TPU bumper pads absorb the impact at stroke extremes.
Because it carries the -S suffix, a built-in piston magnet allows seamless fitting of CMSG, DMSG or EMSG position switches. For practical sizing, plan for a safe working load of roughly 94 N, which equates to lifting about 8 kg vertically with a 2:1 safety margin. The U-style back cover provides a 90-degree port orientation, simplifying hose routing in tight machinery layouts.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100SU Is Used
Package Diverter Gate
Pushes lightweight cardboard cartons on a packaging line using its 157 N push force, with the U back cover keeping pneumatic tubing neatly tucked away.
Textile Loom Tensioner
Cycles rapidly to maintain thread tension in a humid textile facility, relying on the stainless steel rod to shrug off ambient moisture.
Bin Lid Actuation
Lifts an 8 kg access hatch on an automated storage carousel, safely operating within the 94 N safe working load at 0.5 MPa.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X100SU the Right Cylinder?
When sizing this 100 mm stroke unit, the neighbouring bores help frame your decision: stepping down to the Ø16 bore drops the 0.5 MPa push force to 100.5 N, whereas moving up to the Ø25 bore increases it to 245.3 N. The Ø20 bore sits comfortably in the middle for moderate actuation tasks. Remember that a plain double-acting cylinder drifts when air is lost or the valve is centred; the TPU bumpers only decelerate the stroke end and do not act as a brake. If your application requires strict position holding, incorporate an external rod lock or a pilot-operated check valve. Additionally, at 100 mm of travel, ensure your mounting hardware—whether LB foot, FA flange or TC trunnion—prevents side loading to avoid bending the Ø8 mm piston rod.
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 MI20X100SU FAQ
This Ø20 mm bore cylinder uses a 1/8 inch port. 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 force of 32 kgf at 1.0 MPa.
Yes, the Ø20 bore uses the ISO 6432 mounting interface, so it drops directly into standard mini-cylinder brackets and clevises. The -S suffix means it has an internal magnet ready for CMSG, DMSG or EMSG reed and electronic switches.
