About the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X250U
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel mini cylinder handles long 250 mm travel with a compact riveted round body. The Ø16 bore uses a 1/8" port and an M6x1.0 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Built to ISO 6432 mounting dimensions, it drops directly into standard mini-cylinder brackets and clevises.
Fixed TPU bumper pads absorb the impact at stroke extremes without offering adjustable cushioning. For actual work, plan for around 60 N of usable load at 0.5 MPa. Vertically, it lifts about 5.1 kg with a 2:1 safety margin. Because this SKU lacks the -S suffix, it cannot host CMSG, DMSG, or EMSG magnetic switches.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X250U Is Used
Bottle Line Diverter
Pushes light guide rails on a packaging conveyor to sort plastic bottles, using the 250 mm stroke to clear the lane for washdown cycles.
CNC Tool Tray Ejector
Extends to push a loaded tool tray out of an enclosed machining center, relying on the 100.5 N output to overcome drawer friction.
Lab Sample Handler
Moves test tube racks between testing stations in a humid laboratory environment, benefiting from the stainless rod's corrosion resistance.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X250U the Right Cylinder?
When sizing, the Ø12 bore below offers 56.5 N push at 0.5 MPa, while the Ø20 bore above steps up to 157.0 N. This 16 mm option fits nicely between them for medium-duty clamping. The U suffix specifies a 90-degree rear cover, altering your port and pivot orientation. At 250 mm of travel, watch for side loads; keep the rod guided to prevent bending. Remember that venting the valve or losing air lets the piston drift, as the TPU pads only decelerate the end of stroke. Use a pilot check valve or external rod lock if you must hold a suspended load.
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 MI16X250U FAQ
This Ø16 mm bore cylinder features a 1/8" port and an M6x1.0 male rod thread. It generates 100.5 N push and 86.4 N pull at 0.5 MPa, increasing to 140.7 N push and 120.9 N pull at 0.7 MPa. The theoretical maximum force is 20.5 kgf at 1.0 MPa.
No, this specific SKU lacks the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for position sensing. It uses a 90-degree U back cover and fixed TPU bumper pads that decelerate the stroke end rather than acting as an adjustable air cushion.
