Airtac MFJ Adjustable Mini Cylinder MFJ25X225-10
The AirTAC Airtac MFJ Adjustable Mini Cylinder MFJ25X225-10 is a genuine double acting, adjustable stroke JIS-standard round-body mini air cylinder with a Ø25mm bore and 225mm 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 MFJ25X225-10
Fine-tune your extend end position on site with the AirTAC MFJ25X225-10, a JIS-standard round-body mini cylinder built with a SUS304 stainless barrel and riveted aluminium covers. An external adjuster lets you shorten the extend stroke by up to 10 mm, giving a usable extend range of 215 to 225 mm without buying a new unit or adding external stops. This riveted construction is shorter than a comparable ISO 6432 cylinder for the same bore and stroke, saving valuable mounting length.
Delivering 245.3 N push and 206.1 N pull at 0.5 MPa, this double-acting bore 25 unit handles a safe working load of roughly 147 N, lifting about 12.5 kg vertically with a 2:1 margin. The 1/8" port and M10x1.25 male rod thread make integration straightforward. It relies on fixed TPU bumper pads to decelerate the stroke end, and because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac MFJ Adjustable Mini Cylinder MFJ25X225-10 Is Used
Changeover Stations
Dial in the extend position during product changeovers using the 10 mm adjuster, saving setup time on fixtures handling up to 147 N.
Trial Fit Rigs
Perfect for prototyping where the final 215 to 225 mm extend stop is unknown, letting you tweak the end point without swapping hardware.
Variable Position Stops
Adjust the stroke end on light assembly presses to accommodate part variations, utilising the 245.3 N push force precisely.
Is the Airtac MFJ Adjustable Mini Cylinder MFJ25X225-10 the Right Cylinder?
When sizing this adjustable series, compare the real 0.5 MPa push forces: the MFJ20 delivers 157 N, this MFJ25 hits 245.3 N, and the larger MFJ32 provides 402.2 N. The 10 mm adjuster window is ideal for trial fits and line changeovers where the exact 225 mm extend position is not yet final. For mounting, choose LB foot, FA flange, or TC trunnion (SDB and back-cover options are absent on this build). Remember that the bumper only decelerates the stroke end; it is not a lock. If you need to hold a load on air loss, add an external rod lock or pilot check valve.
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 MFJ25X225-10 FAQ
This double-acting cylinder has a 1/8" port and an M10x1.25 male rod thread. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, 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 external adjuster shortens the extend stroke by up to 10 mm on site, giving a 215 to 225 mm range. Fixed TPU bumper pads decelerate the stroke end. Note this SKU lacks a magnet, so it cannot take CMSG or DMSG sensors.
