Airtac MFCJ Adjustable Mini Cylinder MFCJ32X80-100S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X80-100S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 80mm 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 MFCJ32X80-100S
Tune extend travel by up to 100 mm on site with the AirTAC MFCJ32X80-100S, a JIS-standard round-body mini cylinder built for high-speed changeovers. The riveted SUS304 stainless barrel and aluminium covers form a compact body that is shorter than an ISO 6432 unit for the same 32 mm bore and 80 mm stroke. A needle variable air cushion at both ends soaks up end-of-stroke shock, while the -S suffix adds a piston magnet for CMSG, DMSG or EMSG sensors.
Delivering 402.2 N push at 0.5 MPa (563 N at 0.7 MPa) through a 1/4 inch port and M10x1.25 male rod thread, this double-acting actuator handles a safe working load of roughly 241 N. That translates to lifting about 20.5 kg vertically with a 2:1 margin. The external adjuster only shortens the extend stroke; it does not lock the load mid-cycle.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X80-100S Is Used
Press Fit Tuning
Dial in the exact 0-80 mm extend position for inserting delicate connectors, relying on the 241 N safe working load and variable air cushion to prevent impact damage.
High-Speed Diverter
Sort light goods at speed using the 402.2 N push force, tuning the 100 mm extend window on the fly while the needle cushion absorbs end-of-stroke shock.
Carton Forming Stop
Adjust the extend stroke precisely for different box formats, letting the SUS304 barrel resist washdown while the cushion quietly decelerates the 12 mm rod.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X80-100S the Right Cylinder?
Choose the 32 mm bore over the 628.3 N MFCJ40 when your fixture needs roughly 241 N of working force rather than raw thrust. If your application only requires 245.3 N, the smaller MFCJ25 saves space, but the 32 mm bore gives a better safety margin for variable shock loads. The 1/4 inch port and 30-800 mm/s speed range suit brisk cycles.
The 100 mm adjustable window is perfect for trial fits where the exact extend position and end-of-stroke deceleration both need tuning. Because the cushion only decelerates and the piston drifts on air loss, add an external rod lock or pilot check valve for held loads. Mount via LB foot, FA flange or TC trunnion (no SDB), and use the built-in -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 MFCJ32X80-100S FAQ
This 32 mm bore cylinder has a 1/4 inch port and M10x1.25 male rod thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, or 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 100 mm on site, and the variable air cushion at both ends decelerates the piston near stroke end. The -S magnet allows CMSG/DMSG/EMSG sensors. The cushion is not a brake; the piston drifts on air loss, so use an external rod lock for holding.
