Airtac MIJ Adjustable Cylinder MIJ20X225-30S
The AirTAC Airtac MIJ Adjustable Cylinder MIJ20X225-30S is a genuine double acting, adjustable stroke round-body mini air cylinder with a Ø20mm bore and 225mm 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 MIJ20X225-30S
Dial in a precise forward end position on the production floor with the AirTAC MIJ20X225-30S, a round-body stainless steel mini cylinder built for double-acting operation. An external stop screw lets you shorten the extend stroke by up to 30 mm on site, yielding a usable forward travel of 195 to 225 mm without swapping parts. The retract stroke remains full length, and fixed TPU bumper pads absorb the end-of-travel impact.
At 0.5 MPa, this Ø20 bore generates 157 N of push force and 131.9 N of pull force, translating to a safe working load of roughly 94 N or a vertical lift of about 8 kg with a 2:1 margin. The stainless barrel and piston rod supply mild washdown resistance, and the body conforms to the ISO 6432 mounting interface for standard mini brackets. Because this SKU includes the -S magnet, it is ready for CMSG, DMSG, or EMSG position sensing. Air connections use a 1/8" port, and the male rod thread is M8x1.25.

Where the Airtac MIJ Adjustable Cylinder MIJ20X225-30S Is Used
Staged Diverting
Pushes lightweight cartons at 157 N, using the 30 mm extend adjustment to tune the stop distance for varying package sizes on the line.
Tolerance Take-Up
Feeds parts into a machining cell, dialing the forward position in 195-225 mm to compensate for tooling wear without reprogramming controls.
Adjustable Stops
Acts as a movable physical stop for incoming trays, easily shortening the stroke by up to 30 mm to handle different pallet heights.
Is the Airtac MIJ Adjustable Cylinder MIJ20X225-30S the Right Cylinder?
When sizing this actuator, compare its 157 N push force at 0.5 MPa against adjacent bores: a smaller Ø16 MIJ yields 100.5 N, while a larger Ø25 MIJ provides 245.3 N. The 30 mm external adjuster is highly useful for taking up mechanical tolerances or staging feeds, allowing one part number to cover several intermediate stops. Remember that the stop screw only sets the extend end position; it is not a mid-stroke lock. If your application must hold a load vertically during air loss, add an external rod lock or pilot check valve, as the piston will drift. Mounting options include LB foot, FA flange, and TC trunnion (the SDB pivot block 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 MIJ20X225-30S FAQ
This double-acting cylinder uses a 1/8" port. At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it provides 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 30 mm on site, but it only affects the forward end position (retract remains full). The -S suffix means a piston magnet is built-in, allowing you to mount CMSG, DMSG, or EMSG sensors for position detection.
