Airtac MIJ Adjustable Cylinder MIJ20X125-10
The AirTAC Airtac MIJ Adjustable Cylinder MIJ20X125-10 is a genuine double acting, adjustable stroke round-body mini air cylinder with a Ø20mm bore and 125mm 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 MIJ20X125-10
Dial in a precise forward end position on-site with the AirTAC MIJ20X125-10, a round-body stainless steel mini cylinder that lets an external stop screw shorten the extend stroke by up to 10 mm. This means you can tune the usable forward travel down to 115 mm to absorb setup tolerances or cover multiple stop points from a single part number, all while the retract stroke remains full. It operates as a double-acting unit with a 1/8" port and an M8x1.25 male rod thread.
Built with a riveted stainless barrel and rod, it handles mild washdown and corrosion exposure while delivering 157 N of push force at 0.5 MPa. For sizing context, this translates to a safe working load of about 94 N, or roughly 8 kg of vertical lift with a 2:1 safety margin. It conforms to the ISO 6432 mounting interface for easy bracket drops, uses fixed TPU bumper pads for end deceleration, and because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac MIJ Adjustable Cylinder MIJ20X125-10 Is Used
Package Diverter Stop
Fine-tune the 10 mm extend stop to act as a precise physical gate for varying carton widths on a packaging line, using the 157 N push force to halt light boxes without damage.
Tooling Clearance Adjuster
Dial back the forward stroke from 125 mm to safely clear a machining fixture during changeovers, absorbing setup tolerances on the fly without disassembling the cylinder.
Staged Parts Ejector
Push small metal or plastic components out of a chute at a staged intermediate position, relying on the stainless build to resist occasional coolant splashes.
Is the Airtac MIJ Adjustable Cylinder MIJ20X125-10 the Right Cylinder?
When sizing this 20 mm bore, consider that the smaller MIJ16 bore offers 100.5 N push at 0.5 MPa, while the larger MIJ25 provides 245.3 N. The integrated 10 mm adjuster is ideal for taking up mechanical tolerances during changeovers without physically swapping cylinders. Keep in mind the stop screw merely sets the end position; it is not a mid-stroke lock. The piston will drift on air loss, so add an external rod lock or pilot check valve if you need to hold a suspended load vertically.
Mounting options include LB foot, FA flange, and TC trunnion styles, along with CA, U, R, or CM back covers, but the SDB pivot block is not available on this adjustable variant. Because this exact configuration ships without a magnet, position sensing is impossible unless you upgrade to the -S version of the cylinder.
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 MIJ20X125-10 FAQ
This 20 mm bore cylinder features a 1/8" port and an M8x1.25 male rod thread. It generates 157 N push and 131.9 N pull at 0.5 MPa, increasing to 219.8 N push and 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 10 mm on-site, letting you set the forward end position precisely. The retract stroke remains full. This screw is not a mid-stroke lock or brake; the piston will drift if air pressure is lost, so you need an external rod lock for suspended loads. Additionally, this non-S SKU lacks a magnet and cannot accept position sensors.
