Airtac MFJ Adjustable Mini Cylinder MFJ25X10-10S
The AirTAC Airtac MFJ Adjustable Mini Cylinder MFJ25X10-10S 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 MFJ25X10-10S
Fine-tune your extend end-position on-site with the AirTAC MFJ25X10-10S, a JIS-standard round-body mini cylinder featuring a 10 mm external stroke adjuster. This double-acting actuator uses a SUS304 stainless barrel and riveted aluminium covers to resist mild washdown, while its riveted construction yields a shorter overall body than an ISO 6432 unit of the same bore.
Fitted with a 1/8" port and an M10x1.25 male rod thread, it delivers 245.3 N of push force at 0.5 MPa. The built-in piston magnet (-S) supports CMSG, DMSG, and EMSG switches for position sensing. With fixed TPU bumper pads decelerating the stroke ends, it handles a safe working load of roughly 147 N, lifting about 12.5 kg vertically with a 2:1 margin.

Where the Airtac MFJ Adjustable Mini Cylinder MFJ25X10-10S Is Used
Changeover Stations
Dial in the 10 mm extend window during format changes to set new product stops without swapping the actuator.
Trial Fit Rigs
Perfect for prototyping where the final push position is unknown, leveraging the 245.3 N force to test part seating.
Variable Position Stops
Adjust the end-of-stroke externally to fine-tune clamping pressure on delicate components weighing up to 12.5 kg.
Is the Airtac MFJ Adjustable Mini Cylinder MFJ25X10-10S the Right Cylinder?
When sizing this adjustable actuator, compare the real thrust figures: the MFJ20 bore provides 157 N of push force at 0.5 MPa, this MFJ25 hits 245.3 N, and the larger MFJ32 delivers 402.2 N. The 10 mm adjuster window is ideal for trial fits and line changeovers where the exact extend position is not yet finalised.
Mounting options include LB foot, FA flange, and TC trunnion (no SDB or back-cover here). Remember that the bumper pads only decelerate the stroke end; because a plain cylinder drifts on air loss, you must add an external rod lock or pilot check valve to hold a suspended load securely.
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 MFJ25X10-10S FAQ
This 25 mm bore cylinder features a 1/8" air port and an M10x1.25 male rod thread. At 0.5 MPa it generates 245.3 N of push force and 206.1 N of pull force. At 0.7 MPa the push increases to 343.4 N and pull to 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 10 mm on-site without changing the cylinder itself; retract remains full. It uses fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion. The cylinder cannot hold a load on air loss and will drift, so an external rod lock or pilot check valve is required for suspended loads.
