Airtac MFCJ Adjustable Mini Cylinder MFCJ25X200-100S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ25X200-100S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø25mm bore and 200mm 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 MFCJ25X200-100S
Tune extend travel on-site with the AirTAC MFCJ25X200-100S, a JIS-standard round-body mini cylinder offering a 100 mm adjustable window to shorten the extend stroke from its 200 mm nominal maximum. The riveted SUS304 stainless barrel and aluminium covers yield a shorter mounting envelope than an ISO 6432 unit, resisting mild washdown while saving space. Needle-set variable air cushions at both ends soak up high-speed end-of-stroke shock for quiet deceleration.
Delivering 245.3 N push and 206.1 N pull at 0.5 MPa through a 1/8" port, this double-acting actuator provides a safe working load of about 147 N. It lifts approximately 12.5 kg vertically with a 2:1 margin. The -S suffix equips the piston with a magnet for CMSG, DMSG or EMSG position sensing.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X200-100S Is Used
Adjustable Push Assembly
Dial in the exact 100-200 mm extend position for pressing light fittings, using the 245.3 N push force and needle cushions to prevent impact damage.
High-Speed Diverter
Sort mixed product lengths on a line by tuning the extend stroke on the fly, relying on the variable air cushion to absorb rapid cycling shock.
Vertical Lift Stop
Raise or halt lightweight 12.5 kg tote boxes using the adjustable end position, ensuring smooth deceleration at the top of the 200 mm travel.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X200-100S the Right Cylinder?
Selecting between the four bores hinges on force and space. This 25 mm bore pushes 245.3 N at 0.5 MPa, sitting neatly between the 20 mm at 157 N and the 32 mm at 402.2 N. The 100 mm adjustable window is perfect for changeovers where the exact 100-200 mm extend position and end-of-stroke shock both need dialling in.
The variable air cushion only decelerates the piston near the end of travel; it is not a lock or brake, and the cylinder will drift on air loss. For held loads, specify an external rod lock or pilot check valve. Mount via LB foot, FA flange or TC trunnion (no SDB), and use the -S magnet for CMSG/DMSG/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 MFCJ Adjustable Mini Cylinder MFCJ25X200-100S FAQ
This 25 mm bore cylinder uses a 1/8" port. 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 100 mm on-site, giving a usable 100-200 mm window. The -S suffix adds a piston magnet for CMSG, DMSG or EMSG sensors. The air cushions decelerate motion but do not lock the load.
