Airtac MI16-20 Stainless Steel Mini Cylinder MI20X250SCA
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI20X250SCA is a genuine double acting round-body mini air cylinder with a Ø20mm bore and 250mm 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 MI16-20 Stainless Steel Mini Cylinder MI20X250SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 250 mm stroke with a CA pivot clevis. The Ø20 mm bore uses a 1/8 inch port and 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. Fixed TPU bumper pads absorb the impact at stroke extremes, while the rolled riveted body keeps the unit compact.
Because the 157 N rating is a theoretical maximum, plan for a safe working load of about 94 N of real work at 0.5 MPa. That translates to lifting roughly 8 kg vertically with a 2:1 safety margin. The built-in -S magnet supports CMSG, DMSG and EMSG position switches, and the ISO 6432 mounting interface lets it drop directly into standard mini-cylinder brackets.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X250SCA Is Used
Package Diverter Gate
Actuates a routing flap on a packaging line, using the 8 kg vertical lift capacity to shift lightweight cardboard cartons between parallel conveyor belts.
Textile Loom Tensioner
Maintains consistent yarn tension in a humid textile facility, leveraging the stainless steel construction to resist ambient moisture and fibre dust.
Pallet Labelling Arm
Extends 250 mm to press an adhesive label onto incoming pallets, relying on the CA pivot clevis to accommodate slight angular misalignment during the stroke.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X250SCA the Right Cylinder?
When sizing this 250 mm stroke model, compare it against adjacent bores: the smaller Ø16 generates 100.5 N push at 0.5 MPa, while the larger Ø25 provides 245.3 N. If your payload requires holding position during an air loss or valve centre state, remember this cylinder will drift; the TPU pads only decelerate the end of stroke rather than locking the load, so specify an external rod lock or pilot check valve for suspended masses. The long 250 mm rod extension also demands careful alignment to prevent side-loading and premature rod-bending wear.
This SKU includes the CA rear pivot cover for clevis mounting and the -S magnet for electronic or reed sensors. If you need adjustable end-cushioning for high-speed cycles rather than fixed bumpers, consider the MIC 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 MI20X250SCA FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it provides 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa. The air port is 1/8 inch and the male rod thread is M8x1.25.
Yes, the -S suffix denotes a built-in piston magnet, allowing you to mount CMSG, DMSG or EMSG switches for position detection. For deceleration, it uses fixed TPU bumper pads rather than an adjustable air cushion; if you need adjustable cushioning for high speeds, look at the MIC series.
