Airtac MFJ Adjustable Mini Cylinder MFJ25X60-30
The AirTAC Airtac MFJ Adjustable Mini Cylinder MFJ25X60-30 is a genuine double acting, adjustable stroke JIS-standard round-body mini air cylinder with a Ø25mm bore and 60mm 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 MFJ25X60-30
Trim the extend stroke by up to 30 mm directly on the equipment with the AirTAC MFJ25X60-30. This double-acting, JIS-standard round-body mini cylinder uses an external adjuster so you can set the exact end position between 30 and 60 mm without buying a new unit.
Built with a SUS304 stainless steel barrel and riveted aluminium covers, the compact riveted body is intentionally shorter than an ISO 6432 cylinder of the same bore and stroke, saving valuable mounting length while resisting mild washdown. It delivers 245.3 N of push force at 0.5 MPa through a 1/8" port. This translates to a safe working load of roughly 147 N, or enough to lift about 12.5 kg vertically with a 2:1 safety margin. Fixed TPU bumper pads decelerate the piston at the stroke ends.

Where the Airtac MFJ Adjustable Mini Cylinder MFJ25X60-30 Is Used
Changeover Stations
Dial in the extend stroke up to 30 mm during product format changes, allowing rapid repositioning without swapping out the entire cylinder.
Prototype Fitting Rigs
Safely test end positions within the 245.3 N push force range, tweaking the 60 mm base stroke on the fly until the optimal travel is found.
Variable Mechanical Stops
Set precise physical endpoints for light assembly tooling where a 12.5 kg vertical lift capacity is sufficient and space is tightly constrained.
Is the Airtac MFJ Adjustable Mini Cylinder MFJ25X60-30 the Right Cylinder?
When sizing this series, compare the real thrust figures: the MFJ20 bore yields 157 N of push 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, making it ideal for medium-duty positioning. The 30 mm adjustable window is perfect for trial fits and line changeovers where the final extend position is not yet finalized.
Mounting options include LB foot, FA flange, and TC trunnion (no SDB or back-cover mount). Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors. Note that the adjuster only sets the end stop; it does not lock the piston. 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 MFJ25X60-30 FAQ
This 25 mm bore cylinder features a 1/8" port and a Ø10 mm rod with an M10x1.25 male 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 30 mm from the 60 mm base, giving a usable 30-60 mm window. Retract remains full. Fixed TPU bumper pads decelerate the piston at the end of travel. This SKU has no magnet, so it cannot take sensors; choose the -S variant for CMSG/DMSG/EMSG switches.
