Airtac MFCJ Adjustable Mini Cylinder MFCJ32X30-30S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X30-30S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 30mm 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 MFCJ32X30-30S
Trim the extend stroke by up to 30 mm on site and dial in a needle air cushion at each end to absorb high-speed shock. This AirTAC MFCJ32X30-30S is a double-acting, JIS-standard round-body mini cylinder built with a SUS304 stainless barrel and riveted aluminium covers.
It delivers a 402.2 N push force at 0.5 MPa through a 1/4" port, yielding a safe working load of about 241 N or a 20.5 kg vertical lift with a 2:1 margin. The -S magnet enables CMSG, DMSG or EMSG sensors, and the compact body is shorter than an ISO 6432 unit for the same stroke.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X30-30S Is Used
High-Speed Trial Fits
Dial in the 0-30 mm extend window during component trial fits, letting the needle cushion absorb end-of-stroke shock on fast 402.2 N push moves.
Changeover Positioning
Fine-tune the extend end for rapid product changeovers without swapping cylinders, relying on the 241 N safe working load for moderate actuation.
Washdown Sorting Diverters
Deploy the SUS304 stainless body in mildly corrosive washdown zones, using the built-in magnet for DMSG sensors to confirm divert positions.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X30-30S the Right Cylinder?
Weigh this 32 mm bore against the MFCJ40, which steps up to 628.3 N push at 0.5 MPa, or the smaller MFCJ25 at 245.3 N. Choose the 32 mm here when you need moderate force plus on-site stroke tuning for trial fits and changeovers. The external adjuster only shortens the extend end; it does not lock the piston mid-stroke.
Mount via LB foot, FA flange or TC trunnion (no SDB). The variable air cushion decelerates the load near the ends but will not hold position on air loss—if you need the load locked, add an external rod lock or pilot check valve.
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 MFCJ32X30-30S FAQ
This 32 mm bore cylinder has a 1/4" port and a 12 mm rod. It pushes 402.2 N and pulls 345.6 N at 0.5 MPa, or 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical max of 82 kgf at 1.0 MPa. It runs at 30-800 mm/s and uses a variable air cushion at both ends.
The external adjuster shortens the extend stroke by up to 30 mm on site, while the retract stroke remains full. The -S suffix means a piston magnet is built in for CMSG, DMSG or EMSG sensors. The air cushion only decelerates near the end of travel; it is not a brake.
