Airtac MFJ Adjustable Mini Cylinder MFJ25X25-10TC
The AirTAC Airtac MFJ Adjustable Mini Cylinder MFJ25X25-10TC is a genuine double acting, adjustable stroke JIS-standard round-body mini air cylinder with a Ø25mm bore and 25mm 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 MFJ25X25-10TC
Trimming the extend stroke by up to 10 mm on site, this AirTAC MFJ25X25-10TC cylinder lets you dial in the exact end position without buying a new unit or adding external stops. The usable extend range becomes 15 to 25 mm, while the retract stroke remains full, making it highly effective for trial fits and line changeovers where the final position is not yet locked down.
Built as a JIS-standard round-body mini, it features a SUS304 stainless barrel and riveted aluminium covers that resist mild washdown. For the same 25 mm bore and stroke, the riveted body is shorter than an ISO 6432 cylinder, saving valuable mounting length. Delivering 245.3 N of push force at 0.5 MPa, it handles a safe working load of about 147 N, lifting roughly 12.5 kg vertically with a 2:1 margin. The 1/8" port and M10x1.25 male rod thread simplify pneumatic hookups.

Where the Airtac MFJ Adjustable Mini Cylinder MFJ25X25-10TC Is Used
Changeover Dial-In
Fine-tune the 15 to 25 mm extend position during product format changes, using the external adjuster to hit the exact contact point without swapping hardware.
Prototype Trial Fits
Safely test end-of-stroke positions on new rigs, relying on the 245.3 N push force to move lightweight jigs while you determine the optimal final travel.
Variable Position Stops
Act as an adjustable mechanical stop for secondary operations, trimming the extend by up to 10 mm on the fly to accommodate minor part height variations.
Is the Airtac MFJ Adjustable Mini Cylinder MFJ25X25-10TC the Right Cylinder?
When sizing this adjustable series, compare the real thrust figures: the MFJ20 delivers 157 N of push force at 0.5 MPa, while the MFJ32 jumps to 402.2 N. This 25 mm bore sits comfortably in the middle at 245.3 N, ideal for moderate positioning tasks. Choose the adjustable window when you need to fine-tune the extend end during commissioning rather than relying on fixed stops.
This TC trunnion-mount SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors. Remember that the fixed TPU bumper pads only decelerate the stroke end; they do not hold the load. If air pressure drops, the piston drifts, so install an external rod lock or pilot check valve for suspended loads.
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 MFJ25X25-10TC FAQ
This 25 mm bore cylinder features a 1/8" air 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.
An external adjuster shortens the extend stroke by up to 10 mm, giving a usable extend range of 15 to 25 mm; it does not add stroke beyond the base. The cylinder uses fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion. Note that this SKU lacks the -S magnet, so it cannot accept magnetic sensors.
