About the Airtac MIJ Adjustable Cylinder MIJ32X70-20S
Dial in your forward end position on-site with the AirTAC MIJ32X70-20S, a round-body stainless mini cylinder featuring a 20 mm extend-stroke adjustment window. The external stop screw lets you trim the forward stroke from 70 mm down to 50 mm without swapping parts, while the full retract stroke remains unchanged. It uses a 1/8" port and a 12 mm rod with an M10x1.25 male thread.
Built with a riveted stainless-steel barrel and rod, this double-acting unit handles mild corrosion and washdown environments while delivering 402.2 N of push force at 0.5 MPa. The built-in magnet (-S) supports CMSG, DMSG, and EMSG sensors for position feedback. Fixed TPU bumper pads absorb end-of-stroke impacts, and the stop screw acts only as an end-position setter, not a mid-stroke lock.

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 MIJ32X70-20S Is Used
Staged Diverter Stops
Set precise 50-70 mm extend positions to divert packages of varying sizes on a conveyor without changing the cylinder.
Carton Forming Tolerance Take-up
Absorb mechanical tolerances in packaging lines by fine-tuning the forward end stop to press 20 kg carton blanks accurately.
Adjustable Clamping Pins
Dial in the exact clamping reach for different machined parts, using the 402.2 N force to secure components during machining.
Is the Airtac MIJ Adjustable Cylinder MIJ32X70-20S the Right Cylinder?
This 32 mm bore generates 402.2 N push at 0.5 MPa, offering a safe working load around 241 N or a vertical lift of roughly 20.5 kg with a 2:1 margin. If your application requires less force, step down to the 25 mm bore (245.3 N push @0.5 MPa); for heavier loads, move up to the 40 mm bore (628.3 N push @0.5 MPa). The 20 mm adjuster is ideal for taking up mechanical tolerances during setup or covering multiple stop points with one SKU.
Because it is an adjustable-stroke variant, the SDB pivot-block mounting is not available, though LB foot, FA flange, and TC trunnion options remain. The piston will drift on air loss, so add an external rod lock or pilot check valve if you need to hold a suspended load. The -S magnet enables electronic or reed switches, whereas non-S SKUs cannot accept sensors.
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 MIJ32X70-20S FAQ
This 32 mm bore cylinder uses a 1/8" port. It delivers 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical max of 82 kgf at 1.0 MPa.
The external stop screw shortens the extend stroke by up to 20 mm on-site, but it does not lock the position mid-stroke and the piston will drift on air loss. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors.
