About the Airtac MICJ Adjustable Mini Cylinder MICJ40X75-50

Trimming the forward stop by up to 50 mm on site, the AirTAC MICJ40X75-50 lets you dial in a 25-75 mm extend position without swapping hardware. This round-body stainless steel mini cylinder pairs that external stop screw with a needle-adjustable air cushion at both ends, soaking up high-speed shock to protect your tooling. It operates at 30-800 mm/s and runs double-acting via a 1/4" port.

The stainless barrel and rod resist mild corrosion and washdown. Note this SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors without the -S variant.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G. Note: the Ø40 bore is a larger, non-ISO-6432 size.

0.7 MPa739 N
Max (@1.0 MPa)108 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 MICJ40X75-50 Is Used

conveyor_belt

Pallet Diverter Gate

Tune the extend stop on site to route heavy pallets, relying on the stainless build for humid washdown environments.

packaging

Carton Flap Folder

Shorten the forward stroke to 40 mm to fold thick cardboard, letting the dual air cushions absorb the high-speed shock.

Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X75-50 the Right Cylinder?

The 50 mm extend adjuster plus dual air cushions shine in fast set-position moves where you must tune the impact deceleration on the fly. The stop screw sets the end position but is not a mid-stroke lock, and the piston will drift on air loss, so add an external rod lock or pilot check valve for suspended loads. Mount via LB foot, FA flange or TC trunnion (SDB is not offered), and choose back covers CA, U, R or CM.

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 MICJ40X75-50 FAQ

The theoretical maximum force is 128.1 kgf at 1.0 MPa.

An external screw shortens the extend stroke by up to 50 mm, while retract remains full. A needle-set adjustable air cushion at both ends decelerates the piston near stroke ends. This SKU has no magnet, so it cannot take sensors; the -S variant adds a magnet for CMSG, DMSG or EMSG switches.
