The AirTAC MICJ Adjustable Mini Cylinder MICJ40X175-50 is a genuine double acting, double rod, adjustable stroke + cushion round-body mini air cylinder with a Ø40mm bore and 175mm stroke, 1/4" air ports and a stainless-steel barrel and rod for mildly corrosive environments.
Dial in the exact forward stop on-site with the AirTAC MICJ40X175-50, a double-acting round-body stainless steel mini cylinder featuring a 50 mm extend adjustment window. An external stop screw trims the forward end position down from the 175 mm nominal maximum to 125 mm, while the retract stroke remains full length.
Beyond setting the extend endpoint, this unit integrates a variable air cushion at both ends to soak up high-speed kinetic shock without fixed bumpers. The stainless barrel and rod resist mild corrosion and washdown environments. Note this is a non-ISO-6432 Ø40 bore. This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors; choose the -S variant if position sensing is required.

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.

|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 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).

MI-family variants: MI / MIC (double acting ±cushion), MSI / MTI (single acting push / pull), MID / MICD (double rod ±cushion), MIJ / MICJ (double rod, adjustable stroke ±cushion). Back covers CA / U / R / CM. Mounting LB / FA / SDB / TC.
Pushes heavy cartons at high speed on a packaging line, using the 50 mm extend stop to dial in the exact push distance while the dual air cushions absorb the impact at stroke end.
Acts as an adjustable physical stop for incoming pallets, trimming the forward position on-site to match pallet depth without changing the cylinder mount.
Lifts or presses loads up to 32 kg, using the adjustable extend screw to set the precise lower pressing height while the needle cushions decelerate the rapid descent.
When sizing this 40 mm bore, moving down to the Ø32 MICJ drops the 0.5 MPa push force to 402.2 N, while no larger MICJ bore exists above it. The 50 mm extend stop screw and dual adjustable cushions shine in fast, settable-position moves where you need precise endpoint trimming without swapping cylinders. The stop screw sets the forward end position only—it is not a mid-stroke lock.
Because a standard cylinder drifts on air loss, hold a suspended load with an external rod lock or pilot-operated check valve rather than relying on the cushion. For mounting, select LB foot, FA flange, or TC trunnion brackets; the SDB pivot block is not available on this adjustable-stroke build.
Quick checklist
This 40 mm bore cylinder uses a 1/4" port. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 50 mm (usable range 125-175 mm), while needle valves adjust the air cushions at both ends to decelerate high-speed moves. The cushions only slow the piston near the end; they do not lock or hold position. This SKU has no magnet for sensors; use the -S version for CMSG/DMSG/EMSG switches.
