About the Airtac MIJ Adjustable Cylinder MIJ20X300-30SLB
Dial in a precise forward end position on-site with the AirTAC MIJ20X300-30SLB. This double-acting, round-body stainless steel mini cylinder uses an external stop screw to shorten the extend stroke by up to 30 mm, giving you a usable forward range of 270 to 300 mm while retract remains full. The on-site adjustability lets you take up assembly tolerances or cover multiple stop positions from a single part number, entirely avoiding cylinder swaps.
Built with a stainless-steel barrel and rod, the riveted construction handles mild corrosion and washdown environments. It conforms to the ISO 6432 mounting interface for standard mini brackets and features a 1/8" port with an M8x1.25 male rod thread. Delivering 157 N of push force at 0.5 MPa, it provides a safe working load of about 94 N or a 2:1 vertical lift capacity near 8 kg. The -S suffix equips the piston with a magnet for CMSG, DMSG or EMSG sensors, while fixed TPU bumper pads decelerate the stroke ends.

Where the Airtac MIJ Adjustable Cylinder MIJ20X300-30SLB Is Used
Adjustable Pusher Diverter
Trim the 300 mm extend stroke by up to 30 mm to match varying package sizes on a conveyor without physically swapping the cylinder.
Tolerance Take-up Clamp
Use the 157 N push force to hold parts, dialing the exact forward stop on-site to compensate for minor workpiece variations.
Staged Carton Feeder
Set the external screw to stage corrugated cartons accurately, leveraging the 8 kg vertical lift capacity for gentle product handling.
Is the Airtac MIJ Adjustable Cylinder MIJ20X300-30SLB the Right Cylinder?
When sizing this 20 mm bore, step down to an MIJ16 if your load is lighter (100.5 N push at 0.5 MPa) or move up to an MIJ25 for heavier cycles (245.3 N push at 0.5 MPa). The 30 mm external adjuster is highly useful for prototype setup and tolerance take-up, letting you fine-tune the extend endpoint without adding mechanical shims. Keep in mind the stop screw only sets the forward position; it is not a mid-stroke lock, and the piston will drift on air loss. For vertical or suspended loads, fit an external rod lock or pilot check valve.
This SKU includes the LB foot mount and the -S piston magnet for position sensing. You can pair it with CMSG, DMSG or EMSG switches. Mounting options include LB, FA and TC brackets, along with CA, U, R or CM back covers, but note that the SDB pivot block is not available on this adjustable-stroke 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 MIJ20X300-30SLB FAQ
At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it yields 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa. This 20 mm bore cylinder uses a 1/8" air port and an M8x1.25 male rod thread.
An external stop screw shortens the extend stroke by up to 30 mm (usable range 270-300 mm), but retract remains full. The -S suffix means a piston magnet is built-in for CMSG, DMSG or EMSG sensors. The stainless steel build resists mild corrosion, and fixed TPU bumpers decelerate the stroke ends.
