About the Airtac MIJ Adjustable Cylinder MIJ32X350-20S
Dial in a precise forward end position on-site with the AirTAC MIJ32X350-20S, a round-body stainless mini cylinder featuring a 20mm extend-stroke adjustment window. An external stop screw lets you shorten the forward travel from the 350mm nominal maximum down to 330mm, absorbing setup tolerances without swapping parts. The retract stroke remains full length. Built with a riveted stainless-steel barrel and Ø12mm rod, it handles mild corrosion and washdown environments.
Driven by double-acting air at 0.15-1.0 MPa, this Ø32mm bore generates 402.2N of push force and 345.6N of pull at 0.5 MPa. For motion sizing, expect a safe working load around 241N, or a vertical lift capacity of about 20.5kg with a 2:1 safety margin. It uses a 1/8" port and fixed TPU bumper pads to decelerate the stroke end. Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG position switches.

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 Ø32 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MIJ Adjustable Cylinder MIJ32X350-20S Is Used
Staged Diverting Gate
Trimming the extend stroke by up to 20mm lets you fine-tune a diverting gate on a packaging line to match carton widths perfectly without machining new hard stops.
Pallet Changeover Pusher
With 402.2N of push force available at 0.5 MPa, this cylinder repositions a pusher plate for different pallet depths, using the external screw to dial in the exact 330-350mm forward reach.
Fill Head Positioning
Adjust the downward extend stop on a liquid fill head to accommodate various bottle heights on the fly, relying on the stainless construction for washdown resistance.
Is the Airtac MIJ Adjustable Cylinder MIJ32X350-20S the Right Cylinder?
When sizing this unit, step down to the Ø25 bore if your application requires less than 245.3N of push force at 0.5 MPa, or step up to the Ø40 bore if you need to exceed 402.2N and approach 628.3N. The 20mm external adjuster is ideal for taking up mechanical tolerances during changeovers, letting one part number cover several slightly different forward stops.
Remember that the stop screw only sets the extend end position; it is not a mid-stroke lock. The piston will drift if air pressure is lost, so add an external rod lock or pilot check valve for suspended loads. For mounting, utilize LB foot, FA flange, or TC trunnion brackets (the SDB pivot block is not offered 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 MIJ32X350-20S FAQ
This double-acting cylinder uses a 1/8" port and generates 402.2N push / 345.6N pull at 0.5 MPa, and 563N push / 483.8N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 20mm (usable forward travel 330-350mm), while retract remains full. The -S suffix indicates a built-in piston magnet for CMSG/DMSG/EMSG sensors. Fixed TPU bumpers decelerate the stroke ends.
