Airtac MFJ Adjustable Mini Cylinder MFJ25X100-10S
The AirTAC Airtac MFJ Adjustable Mini Cylinder MFJ25X100-10S is a genuine double acting, adjustable stroke JIS-standard round-body mini air cylinder with a Ø25mm bore and 100mm 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 MFJ25X100-10S
Trimming the extend stroke by up to 10 mm on site, the MFJ25X100-10S lets you dial in the exact end position without buying a new cylinder. This JIS-standard round-body mini cylinder features a SUS304 stainless barrel and riveted aluminium covers, giving you a shorter overall length than an equivalent ISO 6432 unit. The built-in magnet (-S) supports CMSG, DMSG, and EMSG switches.
Fitted with a Ø10 mm rod and 1/8" port, this double-acting actuator delivers 245.3 N of push force at 0.5 MPa. That translates to a safe working load of roughly 147 N, or about 12.5 kg of vertical lift with a 2:1 margin. Fixed TPU bumper pads absorb end-of-stroke impact across the 30-800 mm/s speed range, making it ideal for trial fits and line changeovers where the exact stroke is not final.

Where the Airtac MFJ Adjustable Mini Cylinder MFJ25X100-10S Is Used
Changeover Stations
Fine-tune the 10 mm extend window during product changeovers to set precise variable-position stops without swapping hardware.
Trial Fit Rigs
Perfect for prototype rigs where the exact 90-100 mm extend position is unknown, letting you dial in the stroke on the fly.
Light Assembly Jigs
Handles the 147 N safe working load efficiently for pressing or locating light components in compact machining jigs.
Is the Airtac MFJ Adjustable Mini Cylinder MFJ25X100-10S the Right Cylinder?
When sizing this series, compare the real thrust figures: the MFJ20 provides 157 N of push at 0.5 MPa, this MFJ25 hits 245.3 N, and the larger MFJ32 outputs 402.2 N. Choose the 25 mm bore when you need moderate force in a compact footprint. The external adjuster is invaluable for changeover stations or variable-position stops, allowing you to shorten the extend stroke from 100 mm down to 90 mm without adding external stops.
Mounting options include LB foot, FA flange, and TC trunnion (no SDB). Because the -S magnet is present, you can directly mount CMSG, DMSG, or EMSG sensors. Remember that the TPU bumper only decelerates the stroke end; the piston drifts on air loss, so install 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 MFJ25X100-10S FAQ
This 25 mm bore cylinder features a 1/8" port and a Ø10 mm 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 (usable extend 90-100 mm), but it is not a mid-stroke lock. The -S suffix means a piston magnet is built-in for CMSG/DMSG/EMSG sensors. Fixed TPU bumpers decelerate the stroke end.
