Airtac MI16-20 Stainless Steel Mini Cylinder MI16X165SU
The AirTAC Airtac MI16-20 Stainless Steel Mini Cylinder MI16X165SU is a genuine double acting round-body mini air cylinder with a Ø16mm bore and 165mm 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 MI16X165SU
Generating 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 165 mm travel requirement with ease. The 1/8" port supplies air to extend and retract the Ø6 mm rod, while fixed TPU bumper pads absorb the impact at each stroke end. Because the 16 mm bore falls within the Ø8-Ø25 range, the body features an ISO 6432 mounting interface, allowing it to drop directly into standard mini-cylinder brackets and clevises.
The riveted stainless barrel and rod resist mild corrosion, giving it a real edge over painted-steel alternatives in damp or washdown environments. For practical sizing, plan for a safe working load of about 60 N, which translates to lifting a 5.1 kg part vertically with a 2:1 safety margin. This SKU includes a built-in piston magnet (-S) for position sensing, and uses a U-style 90-degree rear cover for compact pivot or port orientation.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X165SU Is Used
Small Parts Ejection
Uses the 100.5 N push force to positively eject stamped metal or plastic components from a die set on an automated press line.
Package Diverting
Employs the 165 mm stroke to push small cartons from a main conveyor belt to a secondary packaging lane at high speed.
Lab Sample Handling
Leverages the stainless construction and 5.1 kg vertical lift capacity to move sample trays in damp pharmaceutical testing environments.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X165SU the Right Cylinder?
When sizing this 16 mm bore against its neighbours, step down to the Ø12 bore if your task requires less than 56.5 N of push at 0.5 MPa, or move up to the Ø20 bore for 157.0 N. The 165 mm stroke sits well within the 500 mm maximum standard stroke limit, though at this length you should ensure the rod is guided to prevent side-loading and rod bending. The U-style 90-degree back cover offers flexible mounting, and the integrated magnet (-S) supports CMSG, DMSG, or EMSG reed and electronic switches.
Remember that a standard double-acting cylinder like this will drift if air pressure is lost or the control valve is centred; the TPU bumpers only decelerate the piston near the stroke end and do not function as a locking brake. To suspend a load safely during an air failure, 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 MI16X165SU FAQ
This 16 mm bore cylinder features a 1/8" air port and an M6x1.0 male 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 -S suffix indicates a built-in piston magnet designed for CMSG, DMSG, and EMSG position switches. For impact absorption, it relies on fixed TPU bumper pads that decelerate the piston at the stroke ends; it does not have an adjustable air cushion.
