About the Airtac MIJ Adjustable Cylinder MIJ20X175-30S
Trimming the forward end by up to 30 mm on site, this double-acting round-body mini cylinder lets you dial in a precise 145 to 175 mm extend position without changing hardware. The Ø20 mm bore delivers 157 N of push force at 0.5 MPa, yielding a safe working load of roughly 94 N or about an 8 kg vertical lift with a 2:1 margin. Retract travel remains full length.
Built with a stainless-steel barrel and rod for mild washdown resistance, the unit conforms to ISO 6432 mounting dimensions for easy bracket interchange. It uses a 1/8 inch port and features a built-in magnet for position sensing. Fixed TPU bumpers decelerate the stroke ends.

Where the Airtac MIJ Adjustable Cylinder MIJ20X175-30S Is Used
Staged Part Ejection
Use the 30 mm extend adjustment to push parts varying distances off a belt without swapping actuators, relying on the 157 N push force to clear obstructions.
Variable Carton Flaps
Fine-tune the forward stroke on the fly to seal different carton depths, using the 8 kg safe vertical lift capacity to hold flaps in place during taping.
Tolerance Take-Up Jig
Absorb mechanical tolerances in machining fixtures by trimming the extend position up to 30 mm, ensuring the 219.8 N peak force applies precisely without over-travel.
Is the Airtac MIJ Adjustable Cylinder MIJ20X175-30S the Right Cylinder?
When sizing this actuator, step down to the Ø16 bore if your layout requires under 100 N of push force at 0.5 MPa, or move up to the Ø25 bore for 245 N when heavier payloads are involved. The 30 mm external stop screw is ideal for absorbing mechanical tolerances during changeovers, letting one part number cover several intermediate stops.
Note 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, install an external pilot check valve. Mounting options include LB, FA, and TC brackets (SDB is unavailable), and the included magnet supports CMSG, DMSG, or EMSG switches.
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 MIJ20X175-30S 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 is 32 kgf at 1.0 MPa. The air port size is 1/8 inch.
An external stop screw shortens the extend stroke by up to 30 mm, allowing a usable forward range of 145 to 175 mm; the retract stroke remains full. The -S suffix indicates a built-in piston magnet for use with CMSG, DMSG, or EMSG sensors.
