About the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X42SCA
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 riveted stainless barrel and rod resist mild corrosion, outperforming painted alternatives in damp or washdown settings. Fixed TPU bumper pads absorb stroke-end impact without offering adjustable cushioning.
Equipped with a built-in piston magnet (-S), it supports CMSG, DMSG, and EMSG switches for position sensing. Plan for a safe working load of roughly 94 N, which translates to lifting about 8 kg vertically with a 2:1 safety margin. The CA rear cover provides an integrated pivot clevis, making it immediately ready for angular movement applications.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X42SCA Is Used
Package Diverter Arm
Swings a lightweight sorting gate on a packaging line using the CA pivot clevis to handle boxes under 8 kg.
Small Press Ejection
Pushes stamped metal parts out of a die, utilizing the 157 N push force to clear lightweight aluminum components.
Lab Sample Handling
Moves fluid sample trays in a humid laboratory environment, relying on the stainless steel rod to resist mild corrosion.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI20X42SCA the Right Cylinder?
When sizing this actuator, the Ø16 mm bore offers a lighter 100.5 N push at 0.5 MPa, while stepping up to the Ø25 mm bore yields 245.3 N if your payload exceeds the 8 kg vertical lift threshold. The 42 mm stroke keeps the rod compact, minimizing bending moments under side loads. Because the -S suffix denotes a magnet, you can directly mount CMSG or DMSG sensors without modifying the cylinder.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered. The TPU bumpers only decelerate the piston near the end of travel and do not function as a locking brake. To suspend a load safely mid-stroke, integrate 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 MI20X42SCA 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.
Yes, the Ø20 mm bore adheres to ISO 6432 mounting dimensions, allowing it to drop into standard mini-cylinder brackets and clevises. The included -S magnet enables direct mounting of CMSG, DMSG, or EMSG switches for position detection.
