Airtac MIJ Adjustable Cylinder MIJ20X35-30S
The AirTAC Airtac MIJ Adjustable Cylinder MIJ20X35-30S is a genuine double acting, adjustable stroke round-body mini air cylinder with a Ø20mm bore and 35mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MIJ Adjustable Cylinder MIJ20X35-30S
Dial in a precise forward end position on-site with the AirTAC MIJ20X35-30S, a round-body stainless steel mini cylinder featuring a 30 mm extend-stroke adjustment window. An external stop screw lets you shorten the forward stroke from its 35 mm nominal length down to 5 mm, absorbing setup tolerances without swapping hardware. Retract remains full stroke.
Driven by 1/8" ports and an Ø8 mm rod with an M8x1.25 male thread, this double-acting actuator delivers 157 N of push force at 0.5 MPa. The stainless barrel and rod resist mild corrosion and washdown environments. Because this is an -S SKU, it includes a built-in piston magnet for CMSG, DMSG, or EMSG position sensing. It conforms to the ISO 6432 mounting interface for standard mini brackets and uses fixed TPU bumper pads to decelerate the stroke end.

Where the Airtac MIJ Adjustable Cylinder MIJ20X35-30S Is Used
Staged Part Feeding
Pushes lightweight carriers down a line. The 30 mm extend adjuster lets you alter the push distance for different product widths without changing the cylinder.
Carton Flap Folding
Folds varying box flaps with precise timing. The 157 N force handles light cardboard easily, while the stop screw dials in the exact fold depth.
Sensor Probe Placement
Extends a testing probe to touch varied component heights. The -S magnet works with DMSG sensors to confirm extension before the adjustable stop makes contact.
Is the Airtac MIJ Adjustable Cylinder MIJ20X35-30S the Right Cylinder?
For lighter duty, the MIJ16 bore steps down to 100.5 N push at 0.5 MPa, while the MIJ25 steps up to 245.3 N if you need more force. Here, the 157 N push translates to a safe working load of about 94 N, or roughly 8 kg of vertical lift with a 2:1 margin. The 30 mm adjuster is ideal for changeover jobs where you need one part number to cover several staged stops.
Remember that the stop screw only trims the extend end position; it is not a mid-stroke lock. The piston will drift on air loss, so add an external rod lock or pilot check valve if you must hold a suspended load. Mount via LB foot, FA flange, or TC trunnion (SDB is not available on this adjustable variant).
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 MIJ Adjustable Cylinder MIJ20X35-30S FAQ
This double-acting cylinder uses a 1/8" air port and delivers 157 N push / 131.9 N pull at 0.5 MPa, and 219.8 N push / 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 30 mm on-site, giving a usable 5-35 mm forward range; retract remains full. The -S suffix means it has a built-in piston magnet for CMSG, DMSG, or EMSG switches. Fixed TPU bumpers decelerate the ends.
