About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X250SCATC
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 ease. The built-in piston magnet (-S) directly supports CMSG, DMSG and EMSG reed or electronic switches for precise end-of-stroke detection. Its 1/8" air port feeds the 8 mm piston rod, while fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning.
Because the stainless barrel and rod resist mild corrosion, this riveted construction outlasts painted alternatives in damp or washdown environments. The Ø20 bore conforms to ISO 6432 mounting dimensions, ensuring it drops directly into standard mini-cylinder brackets and clevises. For real-world sizing, plan for a safe working load of roughly 94 N, which means it can vertically lift about 8 kg with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X250SCATC Is Used
Package Diverting Gate
Actuates a routing flap on a packaging conveyor, using the 157 N thrust to push cartons into secondary lanes at speed.
Vertical Parts Elevator
Lifts lightweight tote bins weighing up to 8 kg between conveyor tiers, leveraging the 250 mm stroke and TC trunnion for smooth pivot.
Lab Sample Ejection
Ejects processed fluid samples from a testing carousel, where the stainless build resists chemical mist and the CMSG sensor confirms ejection.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X250SCATC the Right Cylinder?
When sizing this unit, the Ø16 bore provides a lighter alternative with 100.5 N of push force at 0.5 MPa, whereas stepping up to the Ø25 bore yields 245.3 N if your application demands greater thrust. This model comes equipped with a CA rear pivot cover and a TC trunnion mount, ideal for accommodating slight misalignment on pivoting loads. Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centred; the TPU bumpers only decelerate the stroke end and will not lock the load, so add an external rod lock or pilot check valve if you need to hold position vertically.
With a 250 mm stroke, ensure your guiding structure prevents side-loading to avoid bending the 8 mm rod. The included magnet allows seamless integration with position sensors, and you can explore the MIC variant if your high-speed cycle requires adjustable air cushioning instead of fixed bumpers.
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 MI20X250SCATC FAQ
This Ø20 mm cylinder features a 1/8" air port and an M8x1.25 male rod thread. At 0.5 MPa it generates 157 N of push force and 131.9 N of pull force. At 0.7 MPa, push increases to 219.8 N and pull to 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, the base MI uses fixed TPU bumper pads that decelerate the piston at the stroke end but do not offer adjustable air cushioning. For high-speed applications requiring adjustable cushions, consider the MIC variant. This model does include a piston magnet (-S) for use with CMSG, DMSG or EMSG sensors, and its ISO 6432 mounting dimensions fit standard brackets.
