Airtac MFCJ Adjustable Mini Cylinder MFCJ32X250-40S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X250-40S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 250mm stroke, 1/4" 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 MFCJ32X250-40S
Dial in exact end positions and absorb high-speed impact with the AirTAC MFCJ32X250-40S, a JIS-standard round-body mini cylinder. An external adjuster shortens the extend stroke by up to 40 mm on site, while needle variable air cushions at both ends soak up end-of-stroke shock. This double-acting actuator uses a SUS304 stainless barrel with riveted aluminium covers, offering a shorter mounting length than an ISO 6432 cylinder for the same 32 mm bore and 250 mm stroke.
Delivering 402.2 N push force at 0.5 MPa, it handles a safe working load of roughly 241 N or lifts about 20.5 kg vertically with a 2:1 margin. The 1/4" port and M10x1.25 male rod thread match standard pneumatic layouts. Because this SKU includes the -S magnet, it supports CMSG, DMSG and EMSG switches for position sensing. Note that the cushion only decelerates the load; use an external rod lock or pilot check valve if you need to hold position on air loss.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X250-40S Is Used
High-Speed Diverter
Tune the 40 mm extend window to deflect packages precisely, relying on the variable air cushion to stop the 250 mm stroke smoothly without slamming.
Trial-Fit Clamping
Perfect for prototyping where the exact 241 N safe working load position must be dialed in on-site and the end-of-stroke shock needs soft deceleration.
Vertical Lift Gate
Lifts about 20.5 kg vertically using the 0.5 MPa push force, with the needle cushion absorbing the downward momentum at the end of the retract stroke.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X250-40S the Right Cylinder?
Choose the MFCJ32 over the MFCJ40 when 402.2 N of push force at 0.5 MPa is sufficient, stepping up to the 628.3 N MFCJ40 only if moving heavier masses. The 32 mm bore keeps the body compact while still providing a 40 mm adjustable extend window, ideal for changeovers where both the stroke endpoint and high-speed deceleration require field tuning. Mount via LB foot, FA flange or TC trunnion. The integrated -S magnet allows direct sensor mounting, and the 1/4" port matches the bore's air flow requirements.
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 MFCJ32X250-40S FAQ
This 32 mm bore cylinder has a 1/4" port and M10x1.25 male rod thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical max of 82 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 40 mm on site, while the variable air cushion at both ends decelerates the piston at high speed. The -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG sensors. The cushion only decelerates; it does not lock the load.
