About the Airtac MIJ Adjustable Cylinder MIJ32X500-40S
Dial in a precise forward end position on-site with the AirTAC MIJ32X500-40S, a round-body stainless mini cylinder featuring a 40 mm adjustable extend window. An external stop screw lets you trim the forward stroke from 500 mm down to 460 mm, absorbing setup tolerances and letting one part number cover several stop distances without swapping hardware. The retract stroke remains full length. Built as a double-acting actuator with a stainless-steel barrel and Ø12 mm piston rod, it resists mild corrosion and washdown environments.
This Ø32 mm bore delivers substantial force, pushing with 402.2 N and pulling with 345.6 N at 0.5 MPa. For a reliable setup, a safe working load is roughly 241 N, or about 20.5 kg of vertical lift with a 2:1 margin. Air connects via a 1/8" port, and the male M10x1.25 rod thread handles secure mechanical coupling. Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG position sensing.

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 MIJ32X500-40S Is Used
Long-Reach Diverting
Use the 500 mm stroke to push heavy cartons across a transfer lane, dialing the 40 mm adjuster back to match varying belt widths without repositioning the cylinder.
Tiered Pallet Pressing
Apply up to 402.2 N of push force to seat lids on stacked pallets, using the stop screw to set distinct downward end positions for different container heights.
High-Bay Staging
Extend parts out of a dense storage rack, fine-tuning the forward reach by up to 40 mm to clear adjacent shelving and ensure safe handoff to the outbound conveyor.
Is the Airtac MIJ Adjustable Cylinder MIJ32X500-40S the Right Cylinder?
When sizing this actuator, check both directions: a smaller Ø25 bore yields 245.3 N of push force at 0.5 MPa, while stepping up to a Ø40 bore provides 628.3 N. The Ø32 hits a strong middle ground at 402.2 N. The 40 mm extend adjuster is invaluable for changeover jobs or taking up mechanical tolerance, letting you fine-tune the reach without machining new hard stops. Note that the external screw only sets the forward end position; it is not a mid-stroke lock, and the fixed TPU bumper pads only decelerate the stroke end. 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.
For mounting, you can use LB foot, FA flange, or TC trunnion brackets, along with CA, U, R, or CM back covers. The SDB pivot block is not available on this adjustable variant. Speeds run 30-800 mm/s across an operating pressure range of 0.15-1.0 MPa.
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 MIJ32X500-40S FAQ
At 0.5 MPa this double-acting cylinder pushes with 402.2 N and pulls with 345.6 N. At 0.7 MPa it pushes 563 N and pulls 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. The air port is 1/8".
The external stop screw shortens the extend stroke by up to 40 mm on-site, giving a usable forward range of 460-500 mm; the retract stroke remains full. The -S suffix means a piston magnet is built-in for CMSG, DMSG, or EMSG sensors. The stop screw sets the end position only and does not lock the load.
