Airtac MFJ Adjustable Mini Cylinder MFJ25X110-75
The AirTAC Airtac MFJ Adjustable Mini Cylinder MFJ25X110-75 is a genuine double acting, adjustable stroke JIS-standard round-body mini air cylinder with a Ø25mm bore and 110mm 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 MFJ25X110-75
Trimming the extend end by up to 75 mm on site, this double-acting JIS-standard round-body mini cylinder lets you set a usable forward stroke of 35 to 110 mm without buying a new unit. The riveted aluminium covers and SUS304 stainless barrel resist mild washdown, while the body is shorter than a comparable ISO 6432 cylinder to save valuable mounting length.
Operating at 0.15 to 1.0 MPa, the 25 mm bore generates 245.3 N of push force at 0.5 MPa. This yields a safe working load of roughly 147 N, or about 12.5 kg of vertical lift with a 2:1 margin. The 1/8" port and M10x1.25 male rod thread simplify pneumatic hookups, though this specific SKU lacks the -S magnet and cannot host CMSG, DMSG or EMSG sensors.

Where the Airtac MFJ Adjustable Mini Cylinder MFJ25X110-75 Is Used
Changeover Stations
Dial in the 35 to 110 mm extend position on the fly for product format changes, using the 245.3 N thrust to push light fixtures without re-engineering the stop blocks.
Trial Fit Rigs
Perfect for prototype benches where the final stroke is unknown; shorten the extend end by up to 75 mm on site until the kinematics are proven.
Variable Position Stops
Acts as an adjustable mechanical end stop for 12.5 kg vertical lifts, letting operators fine-tune the resting height without swapping out the whole cylinder.
Is the Airtac MFJ Adjustable Mini Cylinder MFJ25X110-75 the Right Cylinder?
When sizing across the range, the MFJ20 provides 157 N of push force at 0.5 MPa, whereas the MFJ32 jumps to 402.2 N. This MFJ25 sits comfortably in the middle at 245.3 N, making it ideal when the smaller bore lacks thrust but the 32 mm body is too bulky. The 75 mm adjustable window is a major asset for trial fits and line changeovers where the exact end position is not yet finalised.
Mounting options include LB foot, FA flange and TC trunnion (no SDB or back-cover mount is available on this adjustable build). Keep in mind the fixed TPU bumper pads only decelerate the stroke end; they do not lock the piston. If you need to hold a load vertically during air loss, add an external rod lock or pilot-operated 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 MFJ25X110-75 FAQ
This 25 mm bore cylinder features a 1/8" port and an M10x1.25 male rod thread. At 0.5 MPa it pushes with 245.3 N and pulls with 206.1 N. At 0.7 MPa the push force is 343.4 N and the pull force is 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
An external adjuster shortens the extend stroke by up to 75 mm on site, giving a usable forward range of 35 to 110 mm; the retract stroke remains full. The cylinder uses fixed TPU bumper pads to decelerate the stroke end, but these do not act as a lock. Note that this SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG sensors.
