Airtac MFCJ Adjustable Mini Cylinder MFCJ32X80-50
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X80-50 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 MFCJ32X80-50
Trim the extend stroke by up to 50 mm on site and dial in a needle air cushion at each end to absorb high-speed shock. This double-acting JIS-standard round-body mini cylinder pairs a SUS304 stainless steel barrel with riveted aluminium covers, yielding a body that is physically shorter than an ISO 6432 unit for the same 32 mm bore and 80 mm stroke.
Delivering 402.2 N of push force at 0.5 MPa (563 N at 0.7 MPa) through a 12 mm rod and 1/4" port, it suits mid-force changeovers. The usable extend range is 30-80 mm. A practical safe working load is roughly 241 N, lifting about 20.5 kg vertically with a 2:1 margin. Note this SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG sensors.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X80-50 Is Used
High-Speed Part Ejection
Dial in the 50 mm extend window and tune the needle cushion to softly eject 20 kg machined parts at high speed without slamming the end cap.
Adjustable Transfer Stops
Fine-tune the stopping position of 241 N product loads on a conveyor during format changeovers, absorbing the shock of fast-moving packages.
Carton Forming Pushers
Set the exact extend length for folding carton flaps on the fly while the variable air cushion prevents harsh impacts at 800 mm/s.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X80-50 the Right Cylinder?
Weigh this 32 mm bore against the larger MFCJ40, which pushes 628.3 N at 0.5 MPa, or the smaller MFCJ25 at 245.3 N. Choose the 32 mm when you need 402.2 N of push force combined with on-site stroke tuning for trial fits and shock-sensitive changeovers. Mount via LB foot, FA flange or TC trunnion (no SDB or back-cover option exists on this build).
The external adjuster only sets the extend end position; it is not a mid-stroke lock. Furthermore, the variable air cushion merely decelerates the piston near the stroke end. If the application must hold a load on air loss, install an external rod lock or pilot-operated check valve, as the piston will drift.
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 MFCJ32X80-50 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 option, meaning it cannot accept CMSG, DMSG or EMSG switches. You must select the -S variant if you require position sensing. The 50 mm adjuster only shortens the extend stroke, and the variable air cushion decelerates the piston without locking it.
