Airtac MIJ Adjustable Cylinder MIJ8X80-50
The AirTAC Airtac MIJ Adjustable Cylinder MIJ8X80-50 is a genuine double acting, adjustable stroke round-body mini air cylinder with a Ø8mm bore and 80mm stroke, M5×0.8 air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MIJ Adjustable Cylinder MIJ8X80-50
Trimming the forward end by up to 50 mm on site, the AirTAC MIJ8X80-50 lets you tune the extend position from 30 to 80 mm without changing the cylinder. This double-acting, round-body stainless steel mini cylinder conforms to the ISO 6432 mounting interface, dropping directly into standard mini brackets and clevises. The stainless barrel and rod resist mild corrosion and washdown environments.
At 0.5 MPa it delivers 25.1 N of push force and 18.8 N of pull force, yielding a safe working load of roughly 15 N or a vertical lift of about 1.3 kg with a 2:1 margin. The M5x0.8 port and M4x0.7 male rod thread keep the envelope compact. Fixed TPU bumper pads decelerate the piston at the stroke ends, operating at speeds of 30-800 mm/s.

Where the Airtac MIJ Adjustable Cylinder MIJ8X80-50 Is Used
Micro-Dispense Dosing
Dial in the exact 30 mm extend position to meter micro-fluids without swapping cylinders, using the 25.1 N push force to drive a small syringe.
Small Part Ejection
Tune the forward stop to eject delicate plastic components from a mold at varying depths, protecting parts with a safe 15 N working load.
Tolerance Take-Up Gauging
Adjust the extend stroke on the fly to compensate for material thickness variations during light-duty contact checks in a QA station.
Is the Airtac MIJ Adjustable Cylinder MIJ8X80-50 the Right Cylinder?
For lighter tasks, no smaller MIJ bore exists, but stepping up to the MIJ16X100-30 boosts your 0.5 MPa push force significantly to 100.5 N. The 50 mm external stop screw is ideal for taking up mechanical tolerances or staging multiple forward stops from a single part number. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors. You can select LB foot, FA flange, or TC trunnion mounts, plus CA, U, R, or CM back covers, but the SDB pivot block is not available on this adjustable variant.
Remember that the stop screw sets the forward end position but does not function as a mid-stroke lock. The MIJ8X80-50 will drift and cannot hold a load on air loss; for suspended loads, integrate an external rod lock or pilot-operated check valve.
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 MIJ8X80-50 FAQ
This cylinder uses an M5x0.8 air port. At 0.5 MPa it provides 25.1 N of push force and 18.8 N of pull force. At 0.7 MPa, push is 35.2 N and pull is 26.4 N. The theoretical maximum force is 5.1 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 50 mm, allowing you to set the forward end position between 30 and 80 mm. The retract stroke remains full. This screw is not a mid-stroke lock, and because this non-S SKU lacks a magnet, it cannot host position sensors.
