Airtac MFJ Adjustable Mini Cylinder MFJ25X150-75S
The AirTAC Airtac MFJ Adjustable Mini Cylinder MFJ25X150-75S 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 MFJ25X150-75S
Trimming the extend end by up to 75 mm on site, the AirTAC MFJ25X150-75S lets you dial in the exact end position between 75 and 150 mm without buying a new unit. This JIS-standard round-body mini cylinder features a SUS304 stainless barrel and riveted aluminium covers, giving you a shorter overall mounting length than a comparable ISO 6432 build while resisting mild washdown.
Driven by a 10 mm rod through a 1/8" port, the 25 mm bore delivers 245.3 N push and 206.1 N pull at 0.5 MPa. That translates to a safe working load around 147 N, or lifting roughly 12.5 kg vertically with a 2:1 margin. The -S suffix means a piston magnet is factory-fitted, ready for CMSG, DMSG or EMSG position switches.

Where the Airtac MFJ Adjustable Mini Cylinder MFJ25X150-75S Is Used
Changeover Stations
Dial in the 75 to 150 mm extend position during format changes, using the 245.3 N push force to seat varying part sizes without swapping hardware.
Prototype Fit-Ups
Fine-tune the extend endpoint on trial rigs where the final stroke is unknown, relying on the 147 N safe working load for gentle actuation.
Variable Position Stops
Replace hard external stops with the built-in adjuster to set precise 25 mm bore clamping points, lifting up to 12.5 kg vertically with a 2:1 margin.
Is the Airtac MFJ Adjustable Mini Cylinder MFJ25X150-75S the Right Cylinder?
When sizing this series, compare the real thrust: the MFJ20 yields 157 N of push at 0.5 MPa, this MFJ25 hits 245.3 N, and the MFJ32 jumps to 402.2 N. Choose the 25 mm bore when your clamping or lifting force sits in that 147 N safe-load band and you need the 75 mm on-site adjustment window for trial fits or line changeovers.
Mount via LB foot, FA flange or TC trunnion (there is no SDB or back-cover option here). Remember the external adjuster only sets the extend endpoint; it is not a mid-stroke lock. If the rod must hold a load on air loss, add an external rod lock or pilot check valve, as the fixed TPU bumper pads only decelerate the stroke end.
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 MFJ25X150-75S FAQ
This 25 mm bore cylinder uses a 1/8" port and a 10 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 75 mm (usable range 75-150 mm); retract remains full. The -S suffix indicates a built-in piston magnet for CMSG, DMSG or EMSG switches. Fixed TPU bumpers decelerate the ends, but the cylinder needs an external rod lock to hold position on air loss.
