About the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40SCA
Delivering 100.5 N of push force at 0.5 MPa, this double-acting stainless-steel round-body mini cylinder handles compact automation with ease. The Ø16 bore operates on a 1/8" port and features a 40 mm stroke. Its stainless barrel and rod naturally resist mild corrosion, giving it a real edge over painted alternatives in damp or washdown environments. Integrated fixed TPU bumper pads absorb stroke-end impact to protect the mechanism.
Because it carries the -S suffix, an internal piston magnet enables position sensing with CMSG, DMSG or EMSG switches. The built-in CA rear pivot cover allows direct clevis mounting. For practical sizing, plan for a safe working load of about 60 N, which lets you lift roughly 5.1 kg vertically against gravity. The ISO 6432 mounting interface ensures it drops smoothly into standard mini-cylinder brackets.

Where the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40SCA Is Used
Package Diverter Arm
Uses the CA pivot mount to swing a gate on a packaging line, relying on the 100.5 N push force to redirect light cartons at high speed.
Lab Sample Ejector
The stainless-steel construction survives mildly humid laboratory environments, pushing test tubes out of a carousel over a short 40 mm travel.
Small Part Clamp
Secures plastic housings during a ultrasonic welding process, using the internal magnet and a DMSG switch to confirm the clamp is fully extended.
Is the Airtac MI16-20 Stainless Steel Mini Cylinder MI16X40SCA the Right Cylinder?
When sizing this 16 mm bore, compare it against its neighbours: a 12 mm bore yields 56.5 N of push at 0.5 MPa, while stepping up to a 20 mm bore provides 157 N. This model occupies a solid middle ground for moderate force tasks. The 40 mm stroke is well within the 500 mm maximum, keeping the rod highly resistant to bending. Remember that venting the air causes the piston to drift; the bumpers only decelerate the stroke end and do not lock the load. To hold a vertical position securely, add an external rod lock or pilot check valve. The CA back cover provides a pivot point, and the -S magnet supports standard sensors.
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 MI16X40SCA FAQ
This double-acting cylinder uses a 1/8" port. At 0.5 MPa it provides 100.5 N push and 86.4 N pull. At 0.7 MPa it provides 140.7 N push and 120.9 N pull. The theoretical maximum force is 20.5 kgf at 1.0 MPa.
No, the piston will drift if air pressure is lost or the valve is centered; you need an external rod lock or pilot check valve to hold a load. It features fixed TPU bumper pads that decelerate the stroke end, not an adjustable air cushion. The CA rear cover acts as a pivot clevis.
