Airtac MFJ Adjustable Mini Cylinder MFJ25X160-100S
The AirTAC Airtac MFJ Adjustable Mini Cylinder MFJ25X160-100S is a genuine double acting, adjustable stroke JIS-standard round-body mini air cylinder with a Ø25mm bore and 160mm 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 MFJ25X160-100S
Trimming the extend stroke by up to 100 mm on site, this AirTAC MFJ25X160-100S mini cylinder removes the need to buy a new unit when the exact end position is not yet final. The external adjuster lets you dial in a usable extend of 60 to 160 mm, while the retract stroke remains full length. It is a JIS-standard round-body build with a SUS304 stainless barrel and riveted aluminium covers, engineered to be physically shorter than an ISO 6432 cylinder for the same 25 mm bore and 160 mm stroke.
Driven by filtered air at 0.15 to 1.0 MPa through a 1/8" port, the Ø10 mm piston rod delivers 245.3 N of push force at 0.5 MPa. That translates to a safe working load of about 147 N, or lifting roughly 12.5 kg vertically with a 2:1 safety margin. The -S suffix means a piston magnet is installed for CMSG, DMSG or EMSG switches, and fixed TPU bumper pads decelerate the stroke ends without acting as a lock.

Where the Airtac MFJ Adjustable Mini Cylinder MFJ25X160-100S Is Used
Changeover Stations
Dial in the extend stroke up to 100 mm shorter during product changeovers, avoiding the need to swap cylinders when adjusting end stops for a 12.5 kg fixture.
Prototype Set-up Rigs
Fine-tune the forward position on trial assemblies where the exact 60 to 160 mm extend length is unknown, relying on 245.3 N of push force to test the mechanism.
Variable-Position Stops
Act as an adjustable hard stop for light pressing tasks, using the external adjuster to set the depth while the fixed TPU bumpers absorb the end-of-stroke impact.
Is the Airtac MFJ Adjustable Mini Cylinder MFJ25X160-100S the Right Cylinder?
When sizing this adjustable unit, compare the real thrust figures: the 25 mm bore gives 245.3 N push at 0.5 MPa, sitting between the 157 N of an MFJ20 and the 402.2 N of an MFJ32. Choose the 25 mm if you need to shift around 15 kg and want the flexibility to shorten the extend end by up to 100 mm during line changeovers or trial fits. The adjuster only sets the forward end position; it does not function as a mid-stroke lock.
Because a plain cylinder drifts when air is lost, install an external rod lock or pilot-operated check valve if the load must be held. For mounting, select LB foot, FA flange or TC trunnion brackets (SDB is not offered). The -S magnet enables position sensing with CMSG, DMSG or EMSG switches.
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 MFJ25X160-100S FAQ
This 25 mm bore cylinder uses a 1/8" air port and a Ø10 mm rod with an M10x1.25 male thread. It delivers 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 100 mm on site, giving a usable extend of 60 to 160 mm, while the retract remains full. The -S suffix indicates a built-in piston magnet for CMSG, DMSG or EMSG switches. Fixed TPU bumper pads decelerate the stroke ends but do not lock the load.
