Airtac MFCJ Adjustable Mini Cylinder MFCJ32X15-20
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X15-20 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 15mm 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 MFCJ32X15-20
Tune both travel and end-of-stroke shock precisely with this AirTAC adjustable-stroke mini cylinder. The external adjuster shortens the extend stroke by up to 20 mm (usable extend 0-15 mm), while the needle variable air cushion at both ends soaks up high-speed impact for smooth operation. It features a 32 mm bore, a 12 mm rod, and a 1/4" port.
Built as a JIS-standard round-body unit with a SUS304 stainless barrel and riveted aluminium covers, it is shorter than an ISO 6432 cylinder for the same footprint, saving mounting length while resisting mild washdown. Delivering 402.2 N push force at 0.5 MPa, it yields a safe working load of about 241 N. Note this SKU lacks a magnet, so it cannot take a sensor; the -S variant enables CMSG/DMSG/EMSG switches.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X15-20 Is Used
High-Speed Component Pressing
Dial in the exact 0-15 mm extend contact point and use the needle cushion to absorb the 402.2 N pressing impact, ensuring delicate parts are not crushed during automated assembly.
Changeover Sorting Diverter
Quickly shorten the extend stroke by up to 20 mm during product family changeovers, letting the variable air cushion quietly handle the 30-800 mm/s retract shock without re-engineering the station.
Light Carton Flap Folding
Leverage the 241 N safe working load to fold packaging flaps, tuning the cushion to prevent tearing as the cylinder reaches the adjusted end position at high cycle rates.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X15-20 the Right Cylinder?
When sizing this 32 mm bore against the range, the MFCJ25 provides 245.3 N at 0.5 MPa while the larger MFCJ40 offers 628.3 N. This MFCJ32 strikes a middle ground with 402.2 N push and 345.6 N pull at 0.5 MPa, making it ideal for trial fits where the exact extend position and end shock both need on-site tuning. The air cushion decelerates the piston near stroke end but does not lock or hold the load.
Mounting options include LB foot, FA flange, and TC trunnion (no SDB or back-cover). Because this specific code has no -S magnet, it cannot accept position sensing; if you need switches, select the magnet-equipped version. For vertical loads that must stay put on air loss, add an external rod lock or pilot 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 MFCJ32X15-20 FAQ
This 32 mm bore cylinder has a 1/4" port and a 12 mm rod. It generates a push force of 402.2 N and a pull force of 345.6 N at 0.5 MPa. At 0.7 MPa, push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, this specific SKU lacks the -S magnet, so it cannot accept CMSG/DMSG/EMSG switches. The external adjuster shortens the extend stroke by up to 20 mm (usable extend 0-15 mm) to set the end position; it is not a mid-stroke lock. The variable air cushion only decelerates the piston near the ends.
