About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X200SULB
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles a 200 mm stroke with ease. The riveted barrel and rod resist mild corrosion, making it superior to painted alternatives in damp or washdown environments. Its 1/8" port and M8x1.25 male rod thread provide robust pneumatic connections.
Featuring an integrated piston magnet, the unit supports CMSG, DMSG and EMSG switches for position sensing. The U-style 90-degree rear cover pairs with the LB foot bracket for stable base mounting. For practical sizing, plan for roughly 94 N of actual work at 0.5 MPa, which means it can safely lift about 8 kg vertically against gravity.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X200SULB Is Used
Package Diverting Gate
Actuates a routing flap on a packaging line, using the 200 mm stroke to shift parcels cleanly between belts.
Textile Loom Tensioner
Maintains consistent yarn tension in humid textile mills where the stainless steel barrel prevents mild corrosion.
Carton Pusher Assembly
Pushes corrugated cartons into a sealing station, comfortably handling the 8 kg vertical lift equivalent with a 2:1 margin.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X200SULB the Right Cylinder?
When sizing this 20 mm bore, compare it against neighbours: the smaller MI16 yields 100.5 N push, while the larger MI25 provides 245.3 N at 0.5 MPa. This model fits neatly in the middle for medium-duty tasks. The 200 mm stroke is well within the 500 mm maximum, but long extensions demand careful alignment to prevent rod bending and premature seal wear.
The included LB foot bracket secures the body firmly, while the U back cover allows 90-degree pivot options. Remember that the fixed TPU bumper pads only soften stroke-end impacts; they do not act as a brake. If your application must prevent drift on air loss, add an external rod lock or pilot 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 MI20X200SULB FAQ
This 20 mm bore cylinder features a 1/8" port and an M8x1.25 male rod thread. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in magnet for CMSG, DMSG or EMSG switches. However, the fixed TPU bumpers only decelerate the stroke end; they do not lock the piston. The rod will drift if air is lost, so use an external rod lock for holding.
