About the Airtac MICJ Adjustable Mini Cylinder MICJ20X80-100
Trimming the forward stop by up to 100 mm on site, this AirTAC MICJ20X80-100 mini cylinder lets you set a precise 0-80 mm extend position without swapping hardware. The stainless-steel round-body barrel and M8 rod resist mild washdown corrosion, while the needle-adjustable air cushion at both ends soaks up high-speed shock to protect your tooling.
Delivering 157 N of push force at 0.5 MPa, it handles a safe working load of roughly 94 N or lifts about 8 kg vertically with a 2:1 margin. It uses the ISO 6432 mounting interface for standard mini brackets and features a 1/8" port. Note this SKU lacks a magnet, so it cannot host CMSG/DMSG/EMSG sensors.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X80-100 Is Used
Adjustable Stop Clamping
Dial in a custom 0-80 mm extend reach to clamp delicate electronics housings, relying on the 94 N safe working load to secure parts without crushing them.
High-Speed Diverter Gate
Snap the gate into position at 800 mm/s while the adjustable air cushion absorbs the end-of-stroke shock, preventing impact damage to the stainless rod.
Variable Stroke Pusher
Push varied carton sizes from a single station by tuning the forward stop up to 100 mm shorter, using the 157 N thrust to index lightweight boxes.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X80-100 the Right Cylinder?
For lighter duties, the Ø16 bore provides 100.5 N push at 0.5 MPa, whereas stepping up to the Ø25 bore yields 245.3 N if you need more thrust. The external stop screw on this Ø20 model is ideal for fast, settable-position moves, but remember it only trims the extend end and acts as an end stop, not a mid-stroke lock. The piston will drift on air loss, so fit an external rod lock or pilot check valve for holding suspended loads.
Mount using LB foot, FA flange, or TC trunnion brackets, plus CA, U, R, or CM back covers (SDB pivot blocks are not offered on adjustable-stroke variants). Because this specific SKU has no -S magnet, position sensing is unavailable; choose an -S variant if you require CMSG, DMSG, or EMSG switches.
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 MICJ20X80-100 FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it yields 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa, and the air port is 1/8".
An external screw shortens the extend stroke by up to 100 mm (usable 0-80 mm), and a needle valve adjusts the air cushion at both ends to decelerate the piston. The cylinder is double-acting, does not hold position on air loss, and this non-S SKU cannot accept magnetic sensors.
