About the Airtac MIJ Adjustable Cylinder MIJ8X30-20S
Dial in your forward end position on-site with the AirTAC MIJ8X30-20S, a round-body stainless steel mini cylinder built for double-acting operation. An external stop screw lets you shorten the extend stroke by up to 20 mm, providing a usable 10-30 mm forward range without swapping parts. Retract remains a full 30 mm stroke.
Designed with a 4 mm piston rod and an M5x0.8 port, this ISO 6432 mounting interface unit delivers 25.1 N of push force at 0.5 MPa. The stainless barrel and rod resist mild corrosion and washdown environments. Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG position sensing. Fixed TPU bumper pads decelerate the stroke ends, operating smoothly at 30-800 mm/s.

Where the Airtac MIJ Adjustable Cylinder MIJ8X30-20S Is Used
Micro-Clamp Actuation
Provides a 15 N safe working load to secure delicate electronic components, using the 20 mm extend adjustment to dial in the exact clamp depth without crushing parts.
Light-Diverter Gates
Handles small package routing on conveyors by offering a 1.3 kg vertical lift margin, with an on-site stop screw to quickly reconfigure the push distance for different box sizes.
Staged Parts Feeding
Indexes small plastic or metal fasteners in feeding tracks, relying on the -S magnet and CMSG sensors to confirm the trimmed extend position before the next cycle begins.
Is the Airtac MIJ Adjustable Cylinder MIJ8X30-20S the Right Cylinder?
When sizing this 8 mm bore, note that it is the smallest available in the series, offering a safe working load of roughly 15 N (about 60% of its 25.1 N push at 0.5 MPa) and a vertical lift capacity of about 1.3 kg with a 2:1 margin. If you need more force, stepping up to the 10 mm bore increases push to 39.3 N at 0.5 MPa. The 20 mm adjustment window is ideal for taking up mechanical tolerances during setup or covering multiple stop positions with one part number.
Remember that the stop screw only sets the forward end position; it is not a mid-stroke lock, and the piston will drift if air pressure is lost. For load holding, you must add an external rod lock or pilot check valve. You can mount this cylinder using LB foot, FA flange, or TC trunnion brackets, plus CA, U, R, or CM back covers, but the SDB pivot block is not available on 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 MIJ8X30-20S FAQ
This 8 mm bore cylinder features an M5x0.8 port and a 4 mm rod. At 0.5 MPa it provides 25.1 N push and 18.8 N pull. At 0.7 MPa it provides 35.2 N push and 26.4 N pull. The theoretical maximum force is 5.1 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 20 mm on-site, allowing you to set a precise forward end position while the retract stroke remains fixed at 30 mm. The included -S magnet enables use with CMSG, DMSG, or EMSG sensors for position detection.
