Airtac MFJ Adjustable Mini Cylinder MFJ25X200-75
The AirTAC Airtac MFJ Adjustable Mini Cylinder MFJ25X200-75 is a genuine double acting, adjustable stroke JIS-standard round-body mini air cylinder with a Ø25mm bore and 200mm stroke, 1/8" air ports and a SUS304 stainless-steel barrel for mildly corrosive environments. For the same bore and stroke it is shorter than an ISO 6432 cylinder, saving mounting space.

About the Airtac MFJ Adjustable Mini Cylinder MFJ25X200-75
Trimming the extend stroke by up to 75 mm on site, the MFJ25X200-75 lets you dial in the exact end position between 125 and 200 mm without buying a new cylinder. This JIS-standard round-body mini cylinder features a SUS304 stainless barrel and riveted aluminium covers, giving you a shorter mounting envelope than an equivalent ISO 6432 unit while resisting mild washdown.
Driven by a 10 mm rod through a 1/8" port, the 25 mm bore delivers 245.3 N of push force at 0.5 MPa. That translates to a safe working load of roughly 147 N, or about 12.5 kg of vertical lift with a 2:1 margin. Fixed TPU bumpers absorb the impact at stroke end, and because this SKU lacks the -S magnet, it cannot host CMSG, DMSG or EMSG sensors.

Where the Airtac MFJ Adjustable Mini Cylinder MFJ25X200-75 Is Used
Changeover Dial-In
Swap product formats and use the 75 mm adjuster to set a new extend stop on the fly, saving the cost of a dedicated cylinder for each run.
Prototype Fit-Up
Perfect for R&D rigs where the exact 200 mm extend is unknown; fine-tune the end position within the 125 to 200 mm window during testing.
Light Pressing Stops
Delivering 245.3 N of push at 0.5 MPa, it handles light insertion tasks while you tweak the stroke to avoid bottoming out the tooling.
Is the Airtac MFJ Adjustable Mini Cylinder MFJ25X200-75 the Right Cylinder?
When sizing this adjustable-stroke family, compare the real thrust: the MFJ20 yields 157 N at 0.5 MPa, this MFJ25 provides 245.3 N, and the larger MFJ32 jumps to 402.2 N. The 75 mm adjustment window is invaluable for trial fits and line changeovers where the final extend position is not yet finalised.
Mounting options include LB foot, FA flange and TC trunnion (no SDB or back-cover here). Remember that the external adjuster only shortens the extend stroke—it is not a mid-stroke lock. Because the piston drifts on air loss, install an external rod lock or pilot check valve if you need to hold a load safely.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/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/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MFJ Adjustable Mini Cylinder MFJ25X200-75 FAQ
This double-acting 25 mm bore cylinder uses a 1/8" port and a 10 mm rod. It pushes 245.3 N and pulls 206.1 N at 0.5 MPa, or 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical max of 50 kgf at 1.0 MPa. The 200 mm base stroke can be shortened by up to 75 mm via the external adjuster.
No. This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG switches. The external adjuster only sets the extend end position; it does not lock the piston mid-stroke. Fixed TPU bumpers decelerate the stroke end, but for load holding on air loss you need an external rod lock or pilot check valve.
