About the Airtac MIJ Adjustable Cylinder MIJ40X160-50
The external stop screw shortens the extend stroke by up to 50 mm on-site, letting you dial in the exact forward position without changing the cylinder - retract always runs full.
The MIJ40X160-50 uses a riveted stainless barrel and rod for mild corrosion resistance, and the 1/4" port suits standard shop air. Fixed TPU bumper pads soften the stroke end, while the 40 mm bore delivers a theoretical max of 128.1 kgf at 1.0 MPa. This SKU has no magnet, so it cannot accept a magnetic switch.

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 Ø40 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø40mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 N |
| Max (@1.0 MPa) | 108 kgf |
MIJ / MICJ are double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac MIJ Adjustable Cylinder MIJ40X160-50 Is Used
Fixture Stop Positioning
Set the forward stop of a 40 mm bore fixture to within 50 mm of travel using the external screw - ideal for clamping different part widths without rebuilding the stop.
Pallet Staging
Use the adjustable extend stroke to position pallets at varying depths on a conveyor, taking up tolerance in the pallet or the racking with a simple screw turn.
Changeover Adjustment
When switching product sizes on a line, shorten the extend stroke by up to 50 mm to match the new part - no cylinder swap, just a quick screw adjustment.
Is the Airtac MIJ Adjustable Cylinder MIJ40X160-50 the Right Cylinder?
The 50 mm adjustment window suits setups where you need to fine-tune the forward stop position - ideal for tolerance take-up or changeover jobs. Remember the stop screw sets the end position but does not lock the load; use an external rod lock if you need to hold position on air loss. Mounting options include LB foot, FA flange, and TC trunnion (SDB pivot-block is not available on this 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 MIJ40X160-50 FAQ
At 0.5 MPa, push is 628.3 N and pull is 527.8 N. At 0.7 MPa, push is 879.6 N and pull is 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 50 mm. With a 160 mm nominal stroke, you can set the extend end anywhere from 110 mm to 160 mm. The retract stroke is always full. The screw sets the end position only - it is not a mid-stroke lock.
