About the Airtac MIJ Adjustable Cylinder MIJ20X70-10S
Dial in a precise forward end position on-site with the AirTAC MIJ20X70-10S, a round-body stainless steel mini cylinder featuring a 10 mm extend-stroke adjustment window. An external stop screw lets you shorten the forward stroke from its 70 mm nominal length down to 60 mm without swapping parts, while the retract stroke remains full. Built with a riveted stainless barrel and piston rod, it handles mild washdown environments and conforms to the ISO 6432 mounting interface for standard mini brackets.
This double-acting bore delivers 157 N of push force and 131.9 N of pull at 0.5 MPa, yielding a safe working load of about 94 N or a 2:1 vertical lift margin of roughly 8 kg. The 1/8" port and M8x1.25 male rod thread provide robust connections, and the included -S piston magnet supports CMSG, DMSG, or EMSG sensors for position detection. Fixed TPU bumper pads absorb end-of-stroke impacts across the 30-800 mm/s speed range.

Where the Airtac MIJ Adjustable Cylinder MIJ20X70-10S Is Used
Tolerance Take-Up Gauging
Use the 10 mm extend adjuster to fine-tune the contact position on a gauging station, absorbing part tolerances while applying the 157 N push force safely.
Staged Divert Feeds
Trim the forward stroke to hit a precise stop on a diverter arm without re-engineering the mount, leveraging the 8 kg vertical lift margin for light product routing.
Changeover Tooling Stops
Cover multiple product sizes on one machine by dialing the extend end position between 60 and 70 mm, using the M8x1.25 rod for quick tool swaps.
Is the Airtac MIJ Adjustable Cylinder MIJ20X70-10S the Right Cylinder?
When sizing this 20 mm bore, stepping down to the MIJ16 drops the 0.5 MPa push force to 100.5 N, while moving up to the MIJ25 increases it to 245.3 N. The 10 mm external adjuster is ideal for taking up mechanical tolerances during setup or covering multiple stop points with a single part number. Remember that the stop screw only trims the extend end position; it does not function as a mid-stroke lock, and the cylinder will drift on air loss. For suspended loads, specify an external rod lock or pilot check valve.
Mounting options include LB foot, FA flange, and TC trunnion styles, but the SDB pivot block is not available on this adjustable variant. Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG switches for exact end-position feedback.
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 MIJ20X70-10S FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it provides 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa. The air port size is 1/8".
An external stop screw shortens the extend stroke by up to 10 mm on-site, setting the exact forward end position without affecting the full retract stroke. The -S suffix means a piston magnet is built-in, allowing CMSG, DMSG, or EMSG sensors to detect position. Fixed TPU bumpers decelerate the stroke ends.
