Airtac MFCJ Adjustable Mini Cylinder MFCJ32X100-40
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X100-40 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 100mm 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 MFCJ32X100-40
Trim the extend stroke by up to 40 mm on site with this adjustable-stroke, variable-cushion mini cylinder. The JIS-standard round-body build uses a SUS304 stainless barrel and riveted aluminium covers, yielding a shorter mounting length than an ISO 6432 unit of the same bore and stroke.
Driven by filtered air through a 1/4" port, the 32 mm bore delivers 402.2 N push force at 0.5 MPa. The needle air cushion at both ends soaks up high-speed shock for smooth stops, while the computed safe working load is about 241 N (roughly 60% of the 0.5 MPa push force), lifting about 20.5 kg vertically with a 2:1 margin.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X100-40 Is Used
Press Fit Tuning
Dial in the exact 60-100 mm extend position for inserting delicate pins, relying on the 241 N safe working load and needle cushion to prevent impact damage.
High-Speed Diverting
Sort light goods at speed with a 402.2 N push force, using the adjustable stop and air cushion to quietly absorb end-of-stroke energy during rapid changeovers.
Carton Forming Stops
Adjust the extend length on the fly for varying box sizes while the variable cushion brings the 32 mm bore to a smooth halt at up to 800 mm/s.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X100-40 the Right Cylinder?
Weigh this 32 mm bore against the larger MFCJ40, which pushes 628.3 N at 0.5 MPa for heavier tooling, or a smaller MFCJ25 at 245.3 N for lighter duties. The external adjuster lets you fine-tune the extend end position within a 60-100 mm window, ideal for trial fits where end-of-stroke shock also needs tuning via the variable air cushion.
This non-magnet SKU cannot take a magnetic switch; add the -S option for CMSG, DMSG or EMSG sensors. Mount using LB foot, FA flange or TC trunnion (no SDB). Note that the cushion only decelerates the piston—it is not a lock. For position holding on air loss, fit 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 MFCJ32X100-40 FAQ
This 32 mm bore cylinder uses a 1/4" port. At 0.5 MPa it pushes 402.2 N and pulls 345.6 N. At 0.7 MPa it pushes 563 N and pulls 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
This specific SKU lacks a magnet and cannot take a sensor; you need the -S variant for CMSG/DMSG/EMSG switches. The external adjuster shortens the extend stroke by up to 40 mm (usable 60-100 mm), and the needle air cushion decelerates the piston at stroke end.
