About the Airtac MIJ Adjustable Cylinder MIJ32X500-20
Dialing in a long forward reach is simple with this stainless round-body mini cylinder, which lets an external stop screw trim the extend stroke by up to 20 mm on site. The double-acting mechanism drives a 12 mm rod with 402.2 N of push force at 0.5 MPa, yielding a safe working load of roughly 241 N or a 20.5 kg vertical lift with a 2:1 margin. Because the 500 mm stroke is the maximum standard for this bore, the 480-500 mm usable window is ideal for taking up slack in long traverses.
Built with a stainless barrel and rod for mild washdown resistance, this unit breathes through a 1/8" port and hits speeds of 30-800 mm/s. Fixed TPU bumper pads decelerate the stroke ends. Note this non-ISO-6432 32 mm bore lacks a magnet, so it cannot host CMSG/DMSG/EMSG sensors.

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 MIJ32X500-20 Is Used
Long-Transfer Diverting
Pushes heavy cartons across a wide belt with 402.2 N of force, using the 20 mm stop screw to fine-tune the diverting finger reach for varying box widths.
Extended-Reach Pressing
Delivers a 241 N safe working load to seat components deep inside a fixture, trimming the 500 mm extend end to compensate for stack-up tolerances.
High-Bay Staging Stops
Acts as a physical stop for pallets on a gravity conveyor, using the adjustable forward position to handle mixed pallet heights without changing hardware.
Is the Airtac MIJ Adjustable Cylinder MIJ32X500-20 the Right Cylinder?
When sizing this 32 mm bore, stepping down to a 25 mm MIJ drops the 0.5 MPa push force to 245.3 N, while stepping up to a 40 mm MIJ raises it to 628.3 N. The 20 mm extend adjuster is perfect for changeover jobs or absorbing mechanical tolerance over the long 500 mm travel. Retract remains full length, and the stop screw simply sets the forward end position.
The cylinder does not hold its load on air loss, as the piston drifts when valve pressure centers; use an external rod lock or pilot check valve for suspended loads. Mount via LB foot, FA flange or TC trunnion (SDB pivot-block is unavailable here), and remember this specific SKU lacks the -S magnet needed 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 MIJ32X500-20 FAQ
At 0.5 MPa it provides 402.2 N push and 345.6 N pull; at 0.7 MPa it provides 563 N push and 483.8 N pull. The theoretical max force is 82 kgf at 1.0 MPa. It uses a 1/8" air port and a M10x1.25 male rod thread.
An external screw shortens the extend stroke by up to 20 mm on site, giving a 480-500 mm forward range while retract stays full. This SKU has no magnet, so it cannot take CMSG/DMSG/EMSG sensors; you need the -S variant for that. The stop screw sets the end position but is not a mid-stroke lock.
