About the Airtac MICJ Adjustable Mini Cylinder MICJ16X20-20S
Dial in a precise forward stop on-site with the AirTAC MICJ16X20-20S, a stainless-steel round-body mini cylinder that lets you shorten the extend stroke by up to 20 mm via an external screw. Alongside this settable end position, a needle-adjustable air cushion at both ends soaks up high-speed shock, giving you command over both the landing spot and the impact force. It uses the ISO 6432 mounting interface for straightforward bracket interchangeability.
The -S suffix means a built-in magnet is present, ready for CMSG, DMSG or EMSG position sensing. Air connects via an M5×0.8 port.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G.
Theoretical Output Force (Ø16mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 86 N |
| 0.7 MPa | 121 N |
| Max (@1.0 MPa) | 18 kgf |
MIJ / MICJ are double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac MICJ Adjustable Mini Cylinder MICJ16X20-20S Is Used
Micro-Clamp Positioning
Secure delicate electronic components by tuning the 20 mm extend stop to a precise, cushioned contact point, preventing crush damage on parts weighing under 5 kg.
Light Divertor Arm
Actuate a small routing gate at high cycle rates; the dual adjustable air cushions absorb the end-of-stroke shock to keep the 16 mm rod moving smoothly.
Film Feed Tensioner
Nudge packaging web materials with a 60 N working load, using the on-site stroke adjustment to dial in the exact push distance for different fold depths.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ16X20-20S the Right Cylinder?
For lighter tasks, the smaller bore in this adjustable family is the MIJ bumper-only variant, lacking the air cushion; for heavier pushes, stepping up to the MICJ20 yields 157.0 N at 0.5 MPa. Choose this 16 mm bore when your payload is around 60 N and you need repeatable, cushioned stops. The 20 mm extend trim window is ideal for tuning a precise feed distance without machining spacers.
Remember that the stop screw sets the end position but does not lock the piston mid-stroke; if air pressure drops, the rod drifts, so fit an external pilot check valve for suspended loads. Mount using LB foot, FA flange or TC trunnion brackets (the SDB pivot block is not offered on this adjustable variant). Speeds run from 30 to 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 MICJ Adjustable Mini Cylinder MICJ16X20-20S FAQ
This 16 mm bore cylinder uses an M5×0.8 air port. At 0.7 MPa, push increases to 140.7 N and pull to 120.9 N. The theoretical maximum force is 20.5 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 20 mm on-site, letting you set the exact forward end position without swapping cylinders; retract remains full. Needle valves adjust the air cushion at both ends to decelerate the piston near stroke ends (it is not a mid-stroke lock). The -S suffix indicates a built-in magnet for use with CMSG, DMSG or EMSG sensors.
