Airtac MIJ Adjustable Cylinder MIJ20X30-30S
The AirTAC Airtac MIJ Adjustable Cylinder MIJ20X30-30S 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 MIJ20X30-30S
Dial in a precise forward end position on-site with the AirTAC MIJ20X30-30S, a round-body stainless mini cylinder featuring a 30 mm adjustable extend stroke. An external stop screw lets you trim the forward travel anywhere within that 30 mm window, absorbing setup tolerances without swapping hardware. Retract travel remains full length, and the Ø20 mm bore delivers 157 N of push force at 0.5 MPa.
Built with a riveted stainless-steel barrel and rod, this double-acting unit resists mild corrosion and handles washdown environments. It conforms to the ISO 6432 mounting interface for direct bracket interchangeability. The -S suffix equips the piston with a magnet for CMSG, DMSG, or EMSG sensors. Air connects via a 1/8" port, and fixed TPU bumper pads absorb the stroke end impacts.

Where the Airtac MIJ Adjustable Cylinder MIJ20X30-30S Is Used
Adjustable Push Stops
Use the 30 mm extend trim to set precise forwarding stops for parts varying in size, absorbing mechanical tolerances without machining new spacers.
Staged Feed Diverter
Deploy the 157 N push force to index cartons on a washdown line, tweaking the extend length on the fly to route items into different lanes.
Light Assembly Press
Leverage the 8 kg vertical lift capacity to seat light components, adjusting the downward extend stroke to prevent overtravel on delicate parts.
Is the Airtac MIJ Adjustable Cylinder MIJ20X30-30S the Right Cylinder?
When sizing this 20 mm bore, stepping down to a 16 mm MIJ drops the 0.5 MPa push force to 100.5 N, while moving up to a 25 mm MIJ increases it to 245.3 N. The 30 mm external adjuster is ideal for changeover jobs where you need one part number to cover several forward stops. For vertical lifting, expect a safe working load of about 94 N (roughly 60% of the 157 N push force), moving around 8 kg with a 2:1 safety margin.
Remember that the stop screw only sets the end position; it is not a mid-stroke lock. The piston will drift if air pressure drops, so add an external rod lock or pilot check valve for holding suspended loads. Mount using LB foot, FA flange, or TC trunnion brackets (SDB pivot blocks are 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 MIJ20X30-30S FAQ
This 20 mm bore cylinder uses a 1/8" air port and an M8x1.25 male rod thread. At 0.5 MPa it generates 157 N push and 131.9 N pull force. 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, letting you fine-tune the forward end position without changing the cylinder; retract remains full. The -S suffix means a piston magnet is built-in, allowing CMSG, DMSG, or EMSG sensors to detect position.
