About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X210SU
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 210 mm stroke with ease. The Ø20 mm bore uses a 1/8" port and an M8x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted 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 enables position sensing with CMSG, DMSG or EMSG switches. For practical sizing, plan for a safe working load of about 94 N, which equates to lifting an 8 kg part vertically with a 2:1 safety margin. The rear U cover provides a 90-degree port orientation, simplifying hose routing in tight machinery.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X210SU Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 8 kg vertical lift capacity to swing the gate and redirect boxes smoothly.
Bin Lid Lifting Arm
Raises and lowers heavy hopper lids in a damp storage area, where the stainless build prevents mild corrosion from ambient moisture.
Textile Yarn Guide
Shifts a yarn guide carriage across a 210 mm path, relying on the 90-degree U cover port to keep pneumatic lines clear of moving threads.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X210SU the Right Cylinder?
When sizing this 210 mm stroke model, the Ø16 bore below offers 100.5 N of push at 0.5 MPa, whereas the Ø25 bore above steps up to 245.3 N. This Ø20 unit sits comfortably in the middle, pushing 157 N and pulling 131.9 N at 0.5 MPa. At 210 mm of extension, be mindful of side-loading forces that could bend the Ø8 mm piston rod; ensure your mounting guides the load cleanly to prevent premature seal wear.
The U back cover orients the air supply at 90 degrees, which pairs well with FA flange or LB foot brackets. Remember that fixed TPU bumpers only decelerate the stroke end; they do not act as a lock. If air pressure drops, the piston will drift, so fit an external rod lock or pilot-operated check valve if you need to suspend a load safely.
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 MI20X210SU FAQ
This Ø20 mm bore cylinder features a 1/8" 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 means it has a magnet for CMSG, DMSG or EMSG switches. However, it does not hold position on air loss; the piston drifts. The fixed TPU bumpers only decelerate the stroke end, so you must add an external rod lock or pilot check valve to suspend a load.
