Airtac MIJ Adjustable Cylinder MIJ20X30-30TC
The AirTAC Airtac MIJ Adjustable Cylinder MIJ20X30-30TC is a genuine double acting, adjustable stroke round-body mini air cylinder with a Ø20mm bore and 30mm stroke, 1/8" 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 MIJ20X30-30TC
Dial in a precise forward end position on-site with the AirTAC MIJ20X30-30TC, 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 30 mm, absorbing setup tolerances without swapping hardware. The retract stroke remains full length. Driven by a 1/8" port and an Ø8 mm rod with an M8x1.25 male thread, it delivers 157 N of push force at 0.5 MPa. For a reliable safety margin, expect a safe working load around 94 N, or a vertical lift capacity of about 8 kg.
This riveted stainless unit conforms to the ISO 6432 mounting interface for easy bracket drops, resisting mild corrosion and washdown environments. Fixed TPU bumper pads decelerate the piston at the stroke end, operating reliably at speeds from 30 to 800 mm/s across a -20 to +70 C range. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG, or EMSG sensors without upgrading to the -S variant.

Where the Airtac MIJ Adjustable Cylinder MIJ20X30-30TC Is Used
Staged Feed Diverter
Trim the extend stroke up to 30 mm to deflect packages of varying widths on a conveyor without repositioning the cylinder bracket.
Changeover Stop Block
Use the adjustable screw to set multiple forward end positions for short product runs, leveraging the 157 N push force to push parts into a fixture.
Carton Flap Tucker
Fine-tune the forward stroke on-site to tuck varying carton flap heights, using the fixed TPU bumpers to soften the final impact.
Is the Airtac MIJ Adjustable Cylinder MIJ20X30-30TC the Right Cylinder?
When sizing this 20 mm bore, dropping down to an MIJ16 lowers the 0.5 MPa push force to 100.5 N, while stepping up to an MIJ25 raises it to 245.3 N. The 30 mm adjustment window is ideal for changeover jobs where you need one part number to cover several intermediate stops. The TC trunnion mount supports pivoting loads, though the SDB pivot block is not offered on this adjustable series.
Keep in mind the stop screw sets the forward end position but acts purely as a bumper, not a mid-stroke lock. If your application must hold a load vertically during air loss, the piston will drift, requiring an external rod lock or pilot-operated check valve. Additionally, because this SKU is non-magnetic, position sensing is unavailable unless you select the -S magnet option.
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 MIJ20X30-30TC FAQ
This 20 mm bore cylinder uses a 1/8" port and an M8x1.25 male rod thread. 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.
An external stop screw shortens the extend stroke by up to 30 mm on-site, allowing you to set the exact forward end position while the retract stroke remains full. This screw is not a mid-stroke lock, so the piston will drift on air loss. Also, this SKU lacks a magnet, so CMSG/DMSG/EMSG sensors cannot be used unless you choose the -S variant.
