Airtac MFCJ Adjustable Mini Cylinder MFCJ32X100-20
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X100-20 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 MFCJ32X100-20
Tune both the extend reach and the end-of-stroke shock on-site with this 32 mm bore, 100 mm stroke cylinder. A 20 mm external adjuster shortens the extend stroke to a usable 80-100 mm window, while the needle-set variable air cushion at both ends soaks up high-speed impact for smooth deceleration. It delivers 402.2 N of push force at 0.5 MPa, making its safe working load roughly 241 N. Built as a JIS-standard round-body mini with a SUS304 stainless barrel and riveted aluminium covers, the body is intentionally shorter than an ISO 6432 cylinder for the same bore and stroke, saving valuable mounting length while resisting mild washdown.
This double-acting variant uses a 12 mm piston rod, an M10x1.25 male thread, and a 1/4" port. It operates at 30-800 mm/s across a 0.15-1.0 MPa pressure range. Because this specific SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG magnetic switches. The cushion only decelerates the piston near the stroke end; it is not a brake, so fit an external rod lock or pilot check valve if you need to hold a load vertically.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X100-20 Is Used
High-Speed Component Pressing
Dial in the exact 80-100 mm extend reach for pressing lightweight fittings, using the 20 mm adjuster to set the depth while the variable air cushion absorbs the 402.2 N end impact.
Adjustable Transfer Diverter
Fine-tune the actuation length on a sorting line during product changeovers, relying on the 32 mm bore's 241 N safe working load to push cartons smoothly without slamming.
Packaging Flap Folding
Tune the extend stroke and needle cushion for high-speed box folding, ensuring the 12 mm rod retracts fully and extends precisely without crushing the package at the end of travel.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X100-20 the Right Cylinder?
Choose between the two available bores based on your force requirements: the MFCJ32 provides 402.2 N push at 0.5 MPa, while the larger MFCJ40 offers 628.3 N. This 32 mm bore is ideal when you need a safe working load of about 241 N and want a lighter, more compact footprint. The 20 mm adjustable stroke window is perfect for high-speed changeovers or trial fits where the exact end position must be dialed in on the machine, and the variable air cushion lets you tune the deceleration to prevent shock damage.
Mount this JIS-standard cylinder using LB foot, FA flange, or TC trunnion brackets; there is no SDB mount or back-cover option on this adjustable build. Remember that this non-magnet SKU cannot take position sensors. If your changeover sequence requires mid-stroke or end-of-stroke feedback, select the -S magnet variant to enable CMSG, DMSG, or 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 MFCJ32X100-20 FAQ
This 32 mm bore cylinder features a 1/4" port and an 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 maximum force of 82 kgf at 1.0 MPa.
This specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors; you need the -S variant for sensing. The external adjuster shortens the extend stroke by up to 20 mm (usable range 80-100 mm), while the variable air cushion at both ends only decelerates the piston near stroke end and does not lock the load.
