Airtac MFJ Adjustable Mini Cylinder MFJ25X150-10S
The AirTAC Airtac MFJ Adjustable Mini Cylinder MFJ25X150-10S is a genuine double acting, adjustable stroke JIS-standard round-body mini air cylinder with a Ø25mm bore and 150mm 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 MFJ25X150-10S
Trim the extend end by up to 10 mm right at the fixture with the AirTAC MFJ25X150-10S, giving you a usable 140-150 mm forward stroke while keeping full retract. This JIS-standard round-body mini cylinder relies on a SUS304 stainless barrel and riveted aluminium covers, yielding a shorter overall body than an ISO 6432 unit for the same 25 mm bore and 150 mm stroke to save valuable machine space.
Delivering 245.3 N of push force at 0.5 MPa (and 343.4 N at 0.7 MPa), it fits light-duty positioning securely. The built-in piston magnet (-S) supports CMSG, DMSG, and EMSG switches for end-of-stroke sensing. It uses a 1/8" port and fixed TPU bumper pads to decelerate the stroke ends, yielding a safe working load around 147 N or a 12.5 kg vertical lift with a 2:1 margin.

Where the Airtac MFJ Adjustable Mini Cylinder MFJ25X150-10S Is Used
Changeover Stations
Dial in the 140-150 mm extend position during product changeovers using the 10 mm adjuster, avoiding the need to physically swap out cylinders for different part heights.
Trial Fit Rigs
Perfect for prototype testing where the final push position is unknown, letting engineers fine-tune the end point against a 245.3 N push force at 0.5 MPa.
Light Assembly Stops
Acts as a variable-position stop for light components, safely handling a 12.5 kg vertical lift with a 2:1 margin while resisting mild washdown with its SUS304 barrel.
Is the Airtac MFJ Adjustable Mini Cylinder MFJ25X150-10S the Right Cylinder?
Choose between the MFJ20 at 157 N push @0.5 MPa for very light loads, this MFJ25 at 245.3 N, or step up to the MFJ32 at 402.2 N if your fixture needs more authority. The 10 mm external adjuster here is ideal for trial fits and line changeovers where the exact extend position is not yet finalised—you simply turn the adjuster rather than swapping cylinders or adding external stops.
Remember that the fixed TPU bumpers only decelerate the stroke end; they do not lock the rod. If air pressure drops, the piston will drift, so fit an external rod lock or pilot check valve to hold a suspended load. Mounting options include LB foot, FA flange, and TC trunnion (no SDB). The -S magnet is already included for your sensors.
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 MFJ25X150-10S FAQ
This 25 mm bore cylinder has a 1/8" port and a Ø10 mm rod. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, or 343.4 N push and 288.5 N pull at 0.7 MPa. 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 (usable extend 140-150 mm), but it does not add stroke beyond the 150 mm base and is not a mid-stroke lock. The cylinder uses fixed TPU bumper pads to decelerate at the ends, not an adjustable air cushion. The -S suffix means it has a built-in magnet for CMSG/DMSG/EMSG switches.
