Airtac MFCJ Adjustable Mini Cylinder MFCJ32X100-50
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X100-50 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 MFCJ32X100-50
Dial in exact end positions on-site with the AirTAC MFCJ32X100-50, a JIS-standard round-body mini cylinder featuring a 50 mm adjustable extend window and needle-set variable air cushions at both ends. The external adjuster shortens the nominal 100 mm extend stroke down to 50 mm, while the dual cushions absorb high-speed end-of-travel shock for smooth, quiet motion. Its SUS304 stainless barrel and riveted aluminium covers form a compact body that is physically shorter than a comparable ISO 6432 unit, saving valuable machine space without claiming ISO compliance.
Built for double-acting service, this 32 mm bore unit pushes with 402.2 N of force at 0.5 MPa (563 N at 0.7 MPa) and pulls 345.6 N at 0.5 MPa. It uses a 12 mm rod, an M10x1.25 male thread, and a 1/4" port. For sizing, this bore yields a safe working load of roughly 241 N, meaning it can vertically lift about 20.5 kg with a 2:1 safety margin. Note that this specific SKU lacks the -S magnet, so it cannot host CMSG, DMSG, or EMSG reed switches.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X100-50 Is Used
Tooling Trial Fits
Use the 50 mm extend window to fine-tune clamping reach on machining fixtures, letting the 402.2 N push force seat parts securely while the air cushion prevents harsh impacts.
High-Speed Diverting
Sort light packages at high cycle rates; the needle cushion absorbs end shock at up to 800 mm/s, while the 241 N safe working load handles standard diverting arms.
Adjustable Stops
Set precise physical stops for incoming pallets, adjusting the 100 mm stroke down by 50 mm on-site to accommodate different carton sizes without changing the cylinder.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X100-50 the Right Cylinder?
Choose between the two available bores by matching your dynamic load to the thrust curves. The MFCJ32X100-50 provides a 402.2 N push force at 0.5 MPa, whereas stepping up to the MFCJ40 yields 628.3 N for heavier tooling. The 50 mm adjustable window is ideal for trial fits and high-speed changeovers where the exact extend length and end-of-stroke shock both require field tuning. Mount this cylinder using LB foot, FA flange, or TC trunnion brackets; there is no SDB or back-cover option on this adjustable build.
Remember that the variable air cushion only decelerates the piston near the stroke ends—it is not a brake. If gravity or air loss causes the load to drift, you must add an external rod lock or pilot-operated check valve. Furthermore, because this base unit has no -S magnet, position sensing is impossible without switching to the magnet-equipped variant to accept 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 MFCJ32X100-50 FAQ
This 32 mm bore cylinder features a 1/4" port and a 12 mm rod. 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.
No, this specific SKU does not include the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You must select the -S variant for position sensing. The external adjuster only shortens the extend stroke by up to 50 mm; it does not lock the piston mid-stroke.
