Airtac MFCJ Adjustable Mini Cylinder MFCJ25X200-50
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ25X200-50 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 MFCJ25X200-50
Tune extend travel precisely on-site with the AirTAC MFCJ25X200-50, a JIS-standard round-body mini cylinder built from SUS304 stainless steel and riveted aluminium covers. An external adjuster shortens the 200 mm extend stroke by up to 50 mm (usable range 150-200 mm), while a needle variable air cushion at both ends absorbs high-speed end-of-stroke shock. Retract travel remains full length. The body is deliberately shorter than an ISO 6432 cylinder for the same bore and stroke, saving valuable mounting length.
Operating at 0.15-1.0 MPa with a 1/8" port and an Ø10 mm rod (M10x1.25 male thread), this double-acting actuator delivers 245.3 N push and 206.1 N pull at 0.5 MPa. That equates to a safe working load of about 147 N, or lifting roughly 12.5 kg vertically with a 2:1 margin. Note this specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG or EMSG position switches.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X200-50 Is Used
Conveyor Diverter Tuning
Dial in the 150-200 mm extend reach exactly where a 12.5 kg carton meets the divert lane, using the 50 mm window and needle cushion to soften high-speed impacts.
Light Press Fitment
Apply up to 245.3 N of push force for seating small bearings, adjusting the stroke end on-site to prevent over-travel while the air cushion protects the part.
Vertical Lift Stop
Raise lightweight 12.5 kg tote boxes at speed; the variable cushion slows the extend end smoothly, though an external check valve is needed to hold the load on air loss.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ25X200-50 the Right Cylinder?
Weighing MFCJ25 against the adjacent bores: the 25 mm bore pushes 245.3 N at 0.5 MPa, sitting comfortably between the MFCJ20 at 157 N and the MFCJ32 at 402.2 N. Choose the 25 mm when your payload is around 147 N (or a 12.5 kg vertical lift with a 2:1 margin) and you need to avoid the bulk of the 32 mm body. The 50 mm adjustable window is ideal for high-speed changeovers where the exact end position and deceleration both require fine-tuning on the machine. Mount via LB foot, FA flange or TC trunnion (no SDB or back-cover option exists on this build).
Remember that the variable air cushion only decelerates the piston near stroke end; it is not a brake. If the application must hold a load vertically during air loss or valve centring, the piston will drift. Install an external rod lock or pilot-operated check valve. Because this SKU has no -S magnet, skip position sensing or upgrade to the magnetised variant.
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 MFCJ25X200-50 FAQ
This 25 mm bore double-acting cylinder uses a 1/8" port and an Ø10 mm rod. At 0.5 MPa it pushes 245.3 N and pulls 206.1 N. At 0.7 MPa it pushes 343.4 N and pulls 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 50 mm from the 200 mm maximum, giving a usable 150-200 mm range; retract remains full. A needle variable air cushion decelerates the piston at both ends. This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG switches.
