Airtac MFCJ Adjustable Mini Cylinder MFCJ32X40-10S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X40-10S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 40mm 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 MFCJ32X40-10S
Trim the extend stroke by up to 10 mm on-site with this MFCJ32X40-10S mini cylinder, tuning the 40 mm stroke to exact changeover needs. The external adjuster sets the end position while the needle-set variable air cushion at both ends soaks up high-speed shock for smooth, quiet motion.
Built as a JIS-standard round-body unit with a SUS304 stainless barrel and riveted aluminium covers, it is shorter than an ISO 6432 cylinder for the same bore and stroke, saving mounting length. The 32 mm bore uses a 1/4" port and M10x1.25 male rod thread, delivering 402.2 N push force at 0.5 MPa. With a safe working load of about 241 N, it lifts roughly 20.5 kg vertically with a 2:1 margin. The -S suffix enables CMSG, DMSG or EMSG sensors.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X40-10S Is Used
Changeover Actuation
Dial in the 40 mm extend stroke within the 10 mm window during product changeovers, using the variable air cushion to absorb high-speed shock on tooling engagement.
Light Diverter Push
Pushes light packages with a 241 N safe working load, allowing on-site stroke shortening to prevent over-travel when diverting varying box sizes.
Sealing Head Press
Applies up to 402.2 N of push force at 0.5 MPa for packaging seals, using the needle cushion to bring the head to a smooth, quiet stop without slamming.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X40-10S the Right Cylinder?
Compare the 32 mm bore against MFCJ25 (245.3 N at 0.5 MPa) and MFCJ40 (628.3 N at 0.5 MPa) to match your force class. This 32 mm model provides 402.2 N push at 0.5 MPa, making it ideal for shock-sensitive trial fits where both the extend end and end-of-stroke deceleration need on-site tuning.
Mount via LB foot, FA flange or TC trunnion (no SDB or back-cover). The air cushion only decelerates near the stroke end; it is not a lock. If air loss occurs, the piston drifts, so fit an external rod lock or pilot check valve to hold a suspended load.
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 MFCJ32X40-10S FAQ
This 32 mm bore cylinder features a 1/4" port and M10x1.25 male rod thread. At 0.5 MPa it provides 402.2 N push and 345.6 N pull force. At 0.7 MPa it provides 563 N push and 483.8 N pull. The theoretical maximum force is 82 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 10 mm on-site, giving a usable extend range of 30-40 mm; retract remains full. The -S suffix means a built-in magnet is present for CMSG, DMSG or EMSG switches. The variable air cushion only decelerates the piston near the end and does not lock the load.
