About the Airtac MIJ Adjustable Cylinder MIJ32X350-40S
Dial in a precise forward end position on-site with the AirTAC MIJ32X350-40S, 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 350 mm nominal maximum down to 310 mm, absorbing setup tolerances without changing the cylinder. Retract remains at the full stroke length. The double-acting piston delivers 402.2 N of push force at 0.5 MPa.
Built with a riveted stainless-steel barrel and a Ø12 mm piston rod, this unit resists mild corrosion and suits washdown environments. It operates at 30-800 mm/s on a 1/8" port with fixed TPU bumper pads. The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG sensors. With a 0.5 MPa push force, the safe working load is roughly 241 N, translating to a vertical lift capacity of about 20.5 kg with a 2:1 safety margin.

Where the Airtac MIJ Adjustable Cylinder MIJ32X350-40S Is Used
Staged Diverter Gate
Fine-tune the 350 mm extend stroke by up to 40 mm to deflect packages of varying widths on a washdown conveyor without re-engineering the station.
Variable Stroke Pusher
Push cartons into a sealing jaw using the 402.2 N force, adjusting the forward stop on the fly to handle multiple box formats from a single actuator.
Adjustable Case Stop
Use the external screw to set a precise end position for palletizing tasks, taking up mechanical tolerances as the line changes over between product runs.
Is the Airtac MIJ Adjustable Cylinder MIJ32X350-40S the Right Cylinder?
This Ø32 bore provides 402.2 N push at 0.5 MPa, sitting between the smaller Ø25 (245.3 N) and the larger Ø40 (628.3 N). The 40 mm external stop nut is ideal for staging feeds or matching multiple actuators to a fixture, letting one part number cover several stops. Remember that the stop screw only trims the extend end; it is not a mid-stroke lock. The piston will drift on air loss, so add an external rod lock or pilot check valve for suspended loads.
Mounting options include LB foot, FA flange, and TC trunnion brackets, plus CA, U, R, and CM back covers. The SDB pivot block is not available on this adjustable variant. Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG switches for 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 MIJ32X350-40S FAQ
This double-acting cylinder uses a 1/8" port and an M10x1.25 male rod thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, or 563 N push and 483.8 N 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 40 mm, giving a usable forward range of 310-350 mm, while retract stays at the full length. The -S suffix means a piston magnet is built in for CMSG, DMSG, or EMSG sensors. Fixed TPU bumpers decelerate the stroke ends.
