Airtac MFJ Adjustable Mini Cylinder MFJ25X30-10
The AirTAC Airtac MFJ Adjustable Mini Cylinder MFJ25X30-10 is a genuine double acting, adjustable stroke JIS-standard round-body mini air cylinder with a Ø25mm bore and 30mm 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 MFJ25X30-10
Trimming the extend stroke by up to 10 mm on-site, the AirTAC MFJ25X30-10 eliminates the need for external stops during trial fits. This JIS-standard round-body mini cylinder uses a SUS304 stainless barrel with riveted aluminium covers, yielding a shorter mounting envelope than an ISO 6432 unit of the same bore and stroke.
Operating at 0.5 MPa, the 25 mm bore delivers 245.3 N of push force and 206.1 N of pull force, making it suitable for light handling tasks. The 1/8" port and M10x1.25 male rod thread keep connections compact. Because this SKU lacks the -S magnet option, it cannot accept CMSG, DMSG or EMSG sensors.

Where the Airtac MFJ Adjustable Mini Cylinder MFJ25X30-10 Is Used
Changeover Dial Stops
Dial in the extend position within the 10 mm window during product changeovers, avoiding the need to machine new hard stops for every variant.
Lab Test Rigs
Apply the 245.3 N push force to seat samples, tweaking the 20-30 mm usable extend stroke on the fly until the exact contact deflection is found.
Feeder Alignment
Nudge light parts into position using the 147 N safe working load, fine-tuning the end point without swapping out the entire actuator.
Is the Airtac MFJ Adjustable Mini Cylinder MFJ25X30-10 the Right Cylinder?
When sizing this series, compare the real outputs: the MFJ20 provides 157 N of push force at 0.5 MPa, while the MFJ32 jumps to 402.2 N. This MFJ25 sits in the middle at 245.3 N, offering a computed safe working load of roughly 147 N, or vertical lifts of about 12.5 kg with a 2:1 margin. Choose the 10 mm adjustable window when the exact end position is unknown during line changeovers.
Mounting options include LB foot, FA flange and TC trunnion brackets, with no SDB or back-cover mount available. Remember that the fixed TPU bumper pads only decelerate the stroke end; the piston will drift on air loss, so fit an external rod lock or pilot check valve if you need to hold a load.
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 MFJ25X30-10 FAQ
The 25 mm bore has a 1/8" port and generates 245.3 N push / 206.1 N pull at 0.5 MPa, and 343.4 N push / 288.5 N pull at 0.7 MPa. The theoretical maximum force is 50 kgf at 1.0 MPa.
An external adjuster shortens the extend stroke by up to 10 mm on-site, giving a usable extend range of 20-30 mm. The fixed TPU bumper pads only decelerate the end of travel; they do not lock or hold the load on air loss, so you need an external rod lock for holding.
