Airtac MIJ Adjustable Cylinder MIJ20X75-20S
The AirTAC Airtac MIJ Adjustable Cylinder MIJ20X75-20S is a genuine double acting, adjustable stroke round-body mini air cylinder with a Ø20mm bore and 75mm 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 MIJ20X75-20S
Dial in a precise forward end position on-site with the AirTAC MIJ20X75-20S, a round-body stainless steel mini cylinder that lets an external stop screw shorten the extend stroke by up to 20 mm (usable forward travel 55-75 mm) without swapping parts. As a double-acting unit built to the ISO 6432 mounting interface, it drops directly into standard mini brackets and generates 157 N of push force at 0.5 MPa.
The stainless barrel and rod shrug off mild washdown environments, while the built-in magnet (-S) supports CMSG, DMSG and EMSG position switches. Fixed TPU bumpers decelerate the piston at the stroke ends. For vertical moves, expect a safe working load around 94 N, which translates to lifting roughly 8 kg with a 2:1 safety margin. Air connects via a 1/8" port.

Where the Airtac MIJ Adjustable Cylinder MIJ20X75-20S Is Used
Package Diverter Gate
Trim the extend stroke by up to 20 mm to match varying carton widths on the fly, using the 157 N push force to swing diverter arms without overtravel.
Component Press Station
Fine-tune the forward end position to seat light inserts precisely, absorbing mechanical tolerances while keeping the applied force within the 94 N safe working load.
Staged Ejector Chute
Adjust the forward stop to alter the ejection distance for different product lengths, relying on the stainless build to endure mildly humid packing areas.
Is the Airtac MIJ Adjustable Cylinder MIJ20X75-20S the Right Cylinder?
If your setup needs less thrust, the smaller Ø16 bore yields 100.5 N push at 0.5 MPa; stepping up to the Ø25 provides 245.3 N when this 157 N unit is underpowered. The 20 mm adjustment window is ideal for taking up mechanical tolerances or staging feeds across changeover jobs, letting one SKU cover several intermediate stops. Remember that the stop screw only trims the extend end and does not function as a mid-stroke lock; the piston will drift if air pressure is lost, so fit an external pilot check valve for suspended loads. Mount via LB foot, FA flange or TC trunnion (the SDB pivot block is not offered on this adjustable variant), and select CMSG or EMSG sensors to pair with the -S magnet.
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 MIJ20X75-20S FAQ
At 0.5 MPa this double-acting cylinder provides 157 N push and 131.9 N pull. At 0.7 MPa it delivers 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 stop screw shortens the extend stroke by up to 20 mm (setting usable forward travel between 55 and 75 mm), but retract remains full and the screw is not a mid-stroke lock. The -S suffix means a piston magnet is built in for CMSG, DMSG or EMSG sensors.
