About the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X150SU
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 150 mm stroke with a 1/8" port. The riveted barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown settings. Because it carries the -S suffix, a built-in piston magnet allows direct mounting of CMSG, DMSG, or EMSG switches for position sensing.
Plan for roughly 60 N of actual work at 0.5 MPa to maintain a safe margin, which translates to lifting about 5.1 kg vertically. The U-style back cover provides a 90-degree port orientation for tight spatial constraints, while fixed TPU bumper pads absorb the impact at stroke extremes. It operates at speeds between 30 and 800 mm/s without requiring adjustable cushioning.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X150SU Is Used
Diverter Gate Actuation
Pushes lightweight sorting flaps on packaging lines using its 100.5 N thrust, with the U cover keeping air lines neatly tucked away in tight transfer zones.
Lab Sample Ejection
Ejects small test tube racks from analytical equipment, where the stainless build withstands daily chemical wipe-downs and the 150 mm stroke clears the work area.
Small Part Sealing
Applies downward pressure to seal thin film lids on food trays, relying on the -S magnet and DMSG sensors to confirm the press cycle.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X150SU the Right Cylinder?
When sizing this 16 mm bore, stepping down to a 12 mm bore drops the push force to 56.5 N at 0.5 MPa, whereas moving up to a 20 mm bore increases it to 157.0 N. The 150 mm stroke is well within the 500 mm maximum standard stroke limit, meaning no made-to-order modifications are required. The U rear cover dictates a 90-degree entry for the air lines, so verify your manifold or tubing layout has clearance for this orientation.
Note that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the TPU bumpers only soften the end-of-stroke impact and do not function as a braking mechanism. If your application requires the load to remain stationary during a pressure drop, incorporate an external pilot-operated check valve or a dedicated rod lock.
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 MI16X150SU FAQ
This 16 mm bore cylinder features a 1/8" port and a 6 mm piston rod. 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 of 20.5 kgf at 1.0 MPa.
Yes, it conforms to ISO 6432 mounting dimensions for standard mini-cylinder brackets and clevises. The -S suffix denotes an internal magnet, allowing you to attach CMSG, DMSG, or EMSG switches directly to the body for position detection.
