About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SRTC
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation with ease. The Ø20 mm bore operates on a 1/8" port and features an M8x1.25 male rod thread. Its stainless barrel and rod resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Fixed TPU bumper pads absorb stroke-end impact, while the riveted construction keeps the body light.
The built-in magnet supports CMSG, DMSG, and EMSG switches for position sensing. With a 50 mm stroke, plan for roughly 94 N of actual work at 0.5 MPa, which means it can comfortably lift an 8 kg part vertically with a 2:1 safety margin. The rear R cover provides an axial-in port orientation, and the unit conforms to ISO 6432 mounting dimensions for easy bracket integration.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SRTC Is Used
Package Diverter Gate
Actuates a routing flap on a packaging line, using the 50 mm stroke to push parcels weighing up to 8 kg onto a secondary belt.
Lab Sample Ejector
Ejects filled test tube racks from a dispensing station, leveraging the stainless construction to withstand daily chemical wipe-downs.
Small Parts Clamp
Secures plastic housings during an ultrasonic welding process, applying 94 N of holding force to prevent component shifting.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X50SRTC the Right Cylinder?
When sizing this 157 N (0.5 MPa) unit, stepping down to a Ø16 bore yields 100.5 N, whereas a Ø25 bore increases output to 245.3 N. The included TC trunnion mount pairs with the rear R axial port for versatile mechanical layouts. Because the -S magnet is present, you can directly mount CMSG or EMSG sensors without modification.
Remember that a standard cylinder drifts if air pressure drops or the valve is centred, as the fixed TPU pads only decelerate the stroke end rather than locking the rod. To suspend a load safely mid-stroke, incorporate an external pilot-operated check valve or a dedicated rod lock. Operating speed spans 30-800 mm/s.
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 MI20X50SRTC FAQ
This Ø20 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.
No, the piston will drift if air pressure is lost or the valve is centred, as the fixed TPU bumper pads only decelerate the stroke end and do not act as a brake. To maintain a vertical position, you must add an external rod lock or a pilot-operated check valve.
