Airtac MFJ Adjustable Mini Cylinder MFJ25X15-10
The AirTAC Airtac MFJ Adjustable Mini Cylinder MFJ25X15-10 is a genuine double acting, adjustable stroke JIS-standard round-body mini air cylinder with a Ø25mm bore and 15mm 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 MFJ25X15-10
Trimming the extend end by up to 10 mm on-site, the AirTAC MFJ25X15-10 eliminates the need to swap cylinders during trial fits or line changeovers. This JIS-standard round-body mini cylinder uses a riveted SUS304 stainless barrel with aluminium covers, yielding a shorter mounting envelope than an ISO 6432 unit for the same 25 mm bore and 15 mm stroke.
Operating as a double-acting actuator with fixed TPU bumper pads, it delivers 245.3 N of push force at 0.5 MPa. For practical sizing, this equates to a safe working load of roughly 147 N, lifting about 12.5 kg vertically with a 2:1 margin. The bore-fixed 1/8" port and M10x1.25 male rod thread simplify plumbing and mounting. Note that this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac MFJ Adjustable Mini Cylinder MFJ25X15-10 Is Used
Changeover Stations
Fine-tune the 5 to 15 mm extend position on the fly during product format changes without buying new actuators.
Trial Fit Rigs
Dial in the exact end-of-stroke stop during prototype testing, relying on the 245.3 N push force to seat components.
Variable Position Stops
Adjust the extend endpoint externally to accommodate different material thicknesses in small-batch clamping jobs.
Is the Airtac MFJ Adjustable Mini Cylinder MFJ25X15-10 the Right Cylinder?
When choosing between the available bores, the MFJ20 provides 157 N of push force at 0.5 MPa, while the larger MFJ32 jumps to 402.2 N. This MFJ25 sits comfortably in the middle at 245.3 N, making it ideal for medium-duty positioning. The 10 mm adjustable window is perfect for setups where the exact end position is unknown until commissioning. Mounting options include LB foot, FA flange, and TC trunnion (no SDB). Because the adjuster only shortens the extend stroke and the bumper decelerates the end, it will not hold a load on air loss; for vertical loads, 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 MFJ25X15-10 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 maximum of 50 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
The external adjuster shortens the extend stroke by up to 10 mm on-site, giving a usable extend range of 5-15 mm, while retract remains full. The fixed TPU bumpers only decelerate the stroke end; they do not lock or hold the piston. If air is lost, the cylinder drifts, so use an external rod lock for suspended loads.
