Airtac MIJ Adjustable Cylinder MIJ8X60-40
The AirTAC Airtac MIJ Adjustable Cylinder MIJ8X60-40 is a genuine double acting, adjustable stroke round-body mini air cylinder with a Ø8mm bore and 60mm 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 MIJ8X60-40
Dial in your forward end position on the fly with the AirTAC MIJ8X60-40, a round-body stainless steel mini cylinder built for light-duty tasks. An external stop screw lets you shorten the extend stroke by up to 40 mm directly on-site, providing a usable forward range of 20-60 mm without swapping parts. The retract stroke remains full length, and fixed TPU bumper pads decelerate the piston at the end of travel.
This double-acting Ø8 mm bore unit conforms to the ISO 6432 mounting interface, dropping neatly into standard mini brackets and clevises. It delivers 25.1 N of push force at 0.5 MPa, translating to a safe working load of roughly 15 N or a vertical lift of about 1.3 kg with a 2:1 safety margin. The stainless barrel and rod resist mild corrosion and washdown environments. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG, or EMSG sensors; you would need the -S variant for position detection.

Where the Airtac MIJ Adjustable Cylinder MIJ8X60-40 Is Used
Micro-Clamp Positioning
Fine-tune the forward clamp position by up to 40 mm to accommodate delicate part tolerances without re machining fixtures, using the 25.1 N push force for gentle holding.
Light-Diverter Gate
Set the exact extend distance to deflect small lightweight packets on a conveyor, adjusting the stop screw on-site until the routing angle is perfect.
Staged Parts Feeder
Push small components into a staging area with a 1.3 kg vertical lift capacity, dialing in the stroke to prevent crushing fragile items during changeovers.
Is the Airtac MIJ Adjustable Cylinder MIJ8X60-40 the Right Cylinder?
When sizing this 8 mm bore actuator, consider stepping up to the MIJ16 if your load exceeds the 15 N safe working threshold, as the larger bore provides 100.5 N of push at 0.5 MPa. There is no smaller MIJ option below Ø8, making this the baseline for ultra-light forces. The 40 mm adjustment window is highly useful for taking up mechanical tolerances or staging feeds during machine setup. Keep in mind the external stop screw sets the forward end position but acts purely as a stop, not a mid-stroke lock; the piston will drift if air pressure is lost, so add an external rod lock or pilot check valve if you need to hold a load vertically. Mounting options include LB foot, FA flange, and TC trunnion brackets, along with CA, U, R, or CM back covers, but the SDB pivot block is not available for this adjustable variant.
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 MIJ8X60-40 FAQ
This 8 mm bore cylinder features an M5x0.8 air port and a 4 mm rod with an M4x0.7 male thread. At 0.5 MPa it provides 25.1 N of push force and 18.8 N of pull force. At 0.7 MPa, push increases to 35.2 N and pull to 26.4 N. The theoretical maximum force is 5.1 kgf at 1.0 MPa.
An external stop screw allows you to shorten the extend stroke by up to 40 mm on-site, giving a usable forward range of 20 to 60 mm while the retract stroke remains full. This screw only trims the forward end position and does not lock the piston mid-stroke. Additionally, because this SKU lacks the -S magnet option, it cannot be fitted with position sensors.
