Airtac MFJ Adjustable Mini Cylinder MFJ25X10-10
The AirTAC Airtac MFJ Adjustable Mini Cylinder MFJ25X10-10 is a genuine double acting, adjustable stroke JIS-standard round-body mini air cylinder with a Ø25mm bore and 10mm 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 MFJ25X10-10
Dial in the exact extend position on the fly with the AirTAC MFJ25X10-10, a JIS-standard round-body mini cylinder built with a SUS304 stainless barrel and riveted aluminium covers. An external adjuster lets you shorten the extend stroke by up to 10 mm on site, removing the need to buy a new cylinder or add external stops when the exact end position is not yet final.
Delivering 245.3 N of push force at 0.5 MPa (206.1 N pull), this double-acting 25 mm bore unit is shorter than a comparable ISO 6432 cylinder, saving valuable mounting length. It uses a 1/8" port and fixed TPU bumper pads to decelerate the stroke end. Note this SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG sensors.

Where the Airtac MFJ Adjustable Mini Cylinder MFJ25X10-10 Is Used
Changeover Dial-In
Micro-adjust the extend end by up to 10 mm during product changeovers, letting you set new stop positions without swapping out the cylinder.
Trial Fit Rigs
Perfect for prototype benches where the final extend point is unknown, giving 245.3 N of push force to test part placement before locking the design.
Short-Stroke Clamping
Use the compact 10 mm stroke to clamp light assemblies, fine-tuning the contact pressure on site without adding bulky external mechanical stops.
Is the Airtac MFJ Adjustable Mini Cylinder MFJ25X10-10 the Right Cylinder?
When sizing this adjustable family, compare the real 0.5 MPa push figures: the MFJ20 delivers 157 N, this MFJ25 provides 245.3 N, and the larger MFJ32 outputs 402.2 N. The 10 mm adjuster window here is perfect for trial fits and line changeovers where the exact extend position is unknown or needs micro-tuning.
For mounting you can use LB foot, FA flange or TC trunnion brackets (there is no SDB or back-cover option). Remember that the fixed TPU bumper only decelerates the stroke end; it does not lock the piston. If you need to hold a load vertically on air loss, fit an external rod lock or pilot check valve, as the rod will drift.
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 MFJ25X10-10 FAQ
This 25 mm bore double-acting cylinder uses a 1/8" port and a 10 mm piston rod. 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.
The external adjuster shortens the extend stroke by up to 10 mm on site; it does not add stroke beyond the 10 mm base and does not lock the piston mid-stroke. Fixed TPU bumpers only decelerate the end of travel, so you need an external rod lock or pilot check valve to hold a load on air loss.
