About the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X35SR
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact 35 mm stroke tasks with ease. The Ø16 mm bore uses a 1/8" port and an M6x1.0 male rod thread. Its riveted stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments.
The built-in magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing, while the R back cover provides an axial-in port orientation to save space. Fixed TPU bumper pads decelerate the piston at stroke ends. For practical sizing, plan for a safe working load of about 60 N, which means it can lift roughly 5.1 kg vertically with a 2:1 safety margin.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X35SR Is Used
Small Part Ejection
Pushes lightweight plastic mouldings out of an injection press using the 100.5 N push force, with the 35 mm stroke perfectly matching the ejector clearance.
Package Deflection
Sorts small cartons on a packaging line where the stainless build withstands occasional washdowns and the compact 35 mm stroke quickly flicks diverters.
PCB Clamp Arm
Secures delicate electronic boards during assembly, relying on the CMSG sensor via the -S magnet to confirm the 5.1 kg clamping force is applied.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X35SR the Right Cylinder?
When sizing this bore, stepping down to the Ø12 mm model reduces thrust to 56.5 N, whereas stepping up to the Ø20 mm increases it to 157.0 N (both rated at 0.5 MPa). The 35 mm stroke is well within the 500 mm maximum standard stroke for this bore, keeping the rod highly resistant to bending. Because the R cover uses an axial port, ensure your tubing clears the rear mounting surface.
Remember that the fixed TPU bumpers only soften end-of-stroke impacts; they do not function as a lock. If air pressure drops, the piston will drift and drop the load. To maintain vertical position during an air loss or valve shift, fit an external rod lock or a pilot-operated check valve.
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 MI16X35SR FAQ
This Ø16 mm bore cylinder features a 1/8" port and an M6x1.0 rod thread. It generates 100.5 N push and 86.4 N pull at 0.5 MPa, 140.7 N push and 120.9 N pull at 0.7 MPa, with a theoretical maximum force of 20.5 kgf at 1.0 MPa.
Yes, the Ø16 mm bore uses standard ISO 6432 mounting dimensions, so it drops directly into standard mini-cylinder brackets and clevises. Additionally, the -S suffix denotes a built-in piston magnet, allowing you to mount CMSG, DMSG or EMSG reed and electronic switches along the body.
