Airtac MIJ Adjustable Cylinder MIJ20X80-75
The AirTAC Airtac MIJ Adjustable Cylinder MIJ20X80-75 is a genuine double acting, adjustable stroke round-body mini air cylinder with a Ø20mm bore and 80mm 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 MIJ20X80-75
Dial in a precise forward end position on-site with the AirTAC MIJ20X80-75, 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 75 mm, providing a usable forward range of 5-80 mm without changing the cylinder itself. Retract remains at the full 80 mm.
Delivering 157 N of push force at 0.5 MPa, this ISO 6432 mounting-interface unit handles a safe working load of roughly 94 N, or about an 8 kg vertical lift with a 2:1 margin. The stainless barrel and piston rod resist mild corrosion and washdown environments. It uses a 1/8" port and features fixed TPU bumper pads to decelerate the stroke end. Note this SKU lacks a magnet and cannot host CMSG, DMSG, or EMSG sensors.

Where the Airtac MIJ Adjustable Cylinder MIJ20X80-75 Is Used
Adjustable Stop Feeding
Dial in the exact push distance for a staged parts feeder, using the 75 mm adjustment window to accommodate different product lengths without swapping cylinders.
Tolerance Take-Up Clamping
Clamp components reliably with 157 N of push force at 0.5 MPa while fine-tuning the forward stop to compensate for varying material thicknesses on the fly.
Changeover Diverter
Quickly reposition a conveyor diverter gate by turning the external stop screw, setting the extend endpoint precisely for rapid production line changeovers.
Is the Airtac MIJ Adjustable Cylinder MIJ20X80-75 the Right Cylinder?
When sizing, the smaller MIJ16 bore pushes 100.5 N at 0.5 MPa, while the larger MIJ25 pushes 245.3 N. This MIJ20X80-75 fits neatly in the middle, and its 75 mm adjustment window is ideal for taking up mechanical tolerances or covering multiple stop positions from a single part number. The external screw sets the extend endpoint but is not a mid-stroke lock.
For mounting, you can use LB foot, FA flange, or TC trunnion brackets, but the SDB pivot block is not available on this adjustable variant. Because it is a non-magnet SKU, position sensing is not possible. Remember that a standard cylinder drifts on air loss; add an external rod lock or pilot check valve if the load must be held.
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 MIJ20X80-75 FAQ
This double-acting cylinder uses 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, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 75 mm, letting you set the forward end position without replacing the cylinder. Retract remains full stroke. The screw is not a mid-stroke lock, and the cylinder will drift on air loss; use an external rod lock for holding.
