About the Airtac MIJ Adjustable Cylinder MIJ32X80-40S
Dial in your forward end position on-site with the AirTAC MIJ32X80-40S, a round-body stainless steel mini cylinder featuring a 40 mm extend-stroke adjustment window. An external stop screw lets you shorten the forward stroke from its 80 mm nominal length down to 40 mm, absorbing setup tolerances without changing the part number. This double-acting actuator delivers 402.2 N of push force at 0.5 MPa, making it a robust choice for heavier mid-range tooling.
The stainless-steel barrel and piston rod resist mild corrosion and washdown environments. Because this is a non-ISO-6432 32 mm bore, it provides a larger force profile than standard mini sizes while retaining a compact riveted construction. The built-in magnet (-S) supports CMSG, DMSG, and EMSG sensors for position confirmation, and the 1/8" port handles the necessary air volume. Fixed TPU bumper pads decelerate the piston at the stroke ends.

Where the Airtac MIJ Adjustable Cylinder MIJ32X80-40S Is Used
Staged Part Feeding
Use the 40 mm extend adjustment to alter the push-off distance for different carton widths on a single conveyor line, utilizing the 402.2 N force to clear heavy components.
Machining Tolerance Take-Up
Fine-tune the forward clamping position in 32 mm setups to compensate for raw material variance, ensuring precise stops without reprogramming the motion controller.
Variable Depth Cartoning
Set the exact extend length between 40 and 80 mm to push varied product depths into cases, leveraging the 20.5 kg safe vertical lift capacity for heavier packs.
Is the Airtac MIJ Adjustable Cylinder MIJ32X80-40S the Right Cylinder?
When sizing this 32 mm bore, consider the force step: a 25 mm bore provides 245.3 N push at 0.5 MPa, while the larger 40 mm bore yields 628.3 N. This model's 402.2 N push force at 0.5 MPa translates to a safe working load of about 241 N, or roughly 20.5 kg of vertical lift with a 2:1 margin. The 40 mm adjustability window is invaluable for changeover jobs where multiple parts require slightly different forward stops.
Mounting options include LB foot, FA flange, and TC trunnion brackets, plus CA, U, R, and CM back covers, but the SDB pivot block is not available on this adjustable variant. Remember that the stop screw only trims the extend end; it is not a mid-stroke lock. The cylinder will drift on air loss, so add an external rod lock or pilot check valve for suspended loads. The included -S magnet enables reed or electronic position sensing.
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 MIJ32X80-40S FAQ
This 32 mm bore cylinder uses a 1/8" air port. At 0.5 MPa it provides 402.2 N push and 345.6 N pull force. At 0.7 MPa, push increases to 563 N and pull to 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 40 mm on-site, setting the forward end position without affecting the full retract stroke. The -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG sensors for position detection.
