Airtac MFCJ Adjustable Mini Cylinder MFCJ32X50-30S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X50-30S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 50mm 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 MFCJ32X50-30S
Trim the extend stroke by up to 30 mm on site with this double-acting, variable-cushion JIS-standard round-body mini cylinder. The riveted SUS304 stainless barrel and aluminium covers yield a body shorter than an ISO 6432 unit for the same 32 mm bore and 50 mm stroke, saving mounting length while resisting mild washdown.
Delivering 402.2 N of push force at 0.5 MPa through a 1/4" port, it fits a safe working load near 241 N. The needle air cushion at both ends soaks up high-speed shock, and the -S magnet enables CMSG, DMSG or EMSG switches for position sensing.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X50-30S Is Used
Changeover Dial Indexing
Dial in the exact 20-50 mm extend position during format changeovers while the needle cushion absorbs the high-speed indexing shock on a 241 N safe load.
Carton Flap Folding
Fine-tune the folding stroke on the fly for mixed carton sizes; the SUS304 barrel handles light washdown and the cushion prevents slamming at 800 mm/s.
Sensitive Part Seating
Gently seat delicate components using the 30 mm adjuster to limit extension, letting the variable air cushion decelerate the 402.2 N push force smoothly.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X50-30S the Right Cylinder?
Weigh this 32 mm bore against the MFCJ40, which steps up to 628.3 N push at 0.5 MPa, or drop to the MFCJ25 at 245.3 N if your load is lighter. The external adjuster here is ideal for high-speed changeovers where the exact 20-50 mm extend position and end-of-stroke shock both need tuning. Mount via LB foot, FA flange or TC trunnion (no SDB). Remember the air cushion only decelerates; for a held load, add 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 MFCJ32X50-30S FAQ
This 32 mm bore cylinder has 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 max of 82 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 30 mm, and the needle air cushion at both ends decelerates the piston near stroke end. The cushion is not a brake; for load holding on air loss, use an external rod lock. The -S magnet allows CMSG, DMSG or EMSG sensors.
