About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X35SUTC
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 35 mm stroke with a TC trunnion mount and a U 90-degree rear cover. The Ø8 mm piston rod uses an M8x1.25 male thread, and the air supply connects via a 1/8" port. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted-steel or aluminium minis in damp, food, or outdoor environments.
Because the bore uses ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises for easy design changes. The built-in magnet (-S) supports CMSG, DMSG, and EMSG reed or electronic switches for position sensing. Fixed TPU bumper pads decelerate the stroke end to absorb impact.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X35SUTC Is Used
Diverter Gate Actuation
Pushes a lightweight routing flap on a packaging line using its 157 N thrust, with the U 90-degree cover keeping the port orientation tidy against the frame.
Parts Ejection
Kicks small plastic moulded parts out of a machining cell, relying on the stainless build to withstand coolant mist and damp shop conditions.
Clamp Positioning
Moves a secondary workholding clamp 35 mm into place under a CNC spindle, using the TC trunnion to pivot smoothly with the mechanism.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X35SUTC the Right Cylinder?
When sizing this 20 mm bore, the smaller 16 mm option yields 100.5 N of push at 0.5 MPa, while the larger 25 mm bore provides 245.3 N, letting you step up or down based on your exact force needs. The included TC trunnion and U 90-degree back cover supply pivot flexibility for changing rod angles. If your mechanism must hold a vertical load when air is removed or the valve is centred, this cylinder will drift; add an external rod lock or a pilot-operated check valve to secure the payload. The 35 mm stroke keeps the rod compact, minimizing side-load bending, but ensure the front pivot aligns with the load to prevent guide wear.
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 MI20X35SUTC 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" and the male rod thread is M8x1.25.
No, the piston will drift if air is lost or the valve is centred; use an external rod lock or pilot check valve for holding. It features fixed TPU bumper pads that decelerate the stroke end, not an adjustable air cushion. The -S magnet allows CMSG, DMSG, and EMSG sensors for position feedback.
