Airtac MFCJ Adjustable Mini Cylinder MFCJ25X175-50S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ25X175-50S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 175mm 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 MFCJ Adjustable Mini Cylinder MFCJ25X175-50S
Tune extend travel on-site with the AirTAC MFCJ25X175-50S, a JIS-standard round-body mini cylinder featuring a 50 mm adjustable window (yielding a 125-175 mm extend) paired with needle-set variable air cushions at both ends. The SUS304 stainless steel barrel and riveted aluminium covers deliver reliable mild-corrosion resistance, while the integrated -S magnet enables position sensing.
Delivering 245.3 N push and 206.1 N pull at 0.5 MPa via a 1/8" port, this double-acting actuator soaks up high-speed shock smoothly. It provides a safe working load of roughly 147 N and lifts about 12.5 kg vertically with a 2:1 margin. The compact MF body is shorter than an ISO 6432 cylinder for the same stroke, saving valuable mounting length without conforming to that standard.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X175-50S Is Used
High-Speed Diverters
Tunes the 125-175 mm extend stroke to nudge lightweight packages at speed, relying on variable air cushions to halt the 245.3 N push force smoothly without end-cap slamming.
Trial-Fit Assembly
Ideal for prototyping stations where the exact 147 N safe working load contact point varies, letting operators dial in the 50 mm window on-site during product changeovers.
Film Feed Rollers
Handles rapid actuation for packaging lines, using the needle cushion to decelerate the 12.5 kg vertical lift capacity quietly before the retract cycle begins.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X175-50S the Right Cylinder?
Selecting between the 20, 25, 32, and 40 mm bores requires matching your force and speed needs. The MFCJ25 provides 245.3 N push at 0.5 MPa, sitting neatly between the MFCJ20 at 157 N and the MFCJ32 at 402.2 N. Choose this 25 mm bore when driving lighter high-speed platens that need precise end-position tuning and shock absorption. The external adjuster only shortens the extend stroke; it does not lock the piston mid-travel.
For changeovers where the exact extend endpoint and end-of-stroke shock both need tweaking, the 50 mm window and variable air cushion excel. Remember that air loss causes piston drift—the cushion decelerates but never locks the load, so fit an external rod lock or pilot check valve for holding. Mount via LB foot, FA flange, or TC trunnion (no SDB), and use CMSG, DMSG, or EMSG switches with the built-in -S magnet.
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 MFCJ Adjustable Mini Cylinder MFCJ25X175-50S FAQ
This 25 mm bore cylinder has a 1/8" port and generates 245.3 N push / 206.1 N pull at 0.5 MPa, and 343.4 N push / 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 50 mm (usable range 125-175 mm), while the variable air cushion at both ends decelerates the piston near stroke end to absorb high-speed shock. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors.
