Airtac MFCJ Adjustable Mini Cylinder MFCJ20X65-10
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ20X65-10 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 65mm stroke, 1/8" 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 MFCJ20X65-10
Dial in exact end positions and absorb high-speed shock with the AirTAC MFCJ20X65-10, a JIS-standard round-body mini cylinder. The external adjuster shortens the extend stroke by up to 10 mm on site, giving a usable 55-65 mm window, while needle air cushions at both ends soak up end-of-stroke impact. Built with a SUS304 stainless barrel and riveted aluminium covers, it is shorter than an ISO 6432 cylinder for the same envelope and resists mild washdown.
Fitted with an 8 mm rod, M8x1.25 male thread and a 1/8" port, this double-acting unit delivers 157 N push and 131.9 N pull at 0.5 MPa. That translates to a safe working load of roughly 94 N, or lifting about 8 kg vertically with a 2:1 margin. Note this SKU lacks the -S magnet, so it cannot accept CMSG/DMSG/EMSG sensors.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X65-10 Is Used
Light-Part Ejection
Tune the 10 mm extend window to eject 8 kg plastic parts precisely, letting the variable air cushion absorb the impact at 800 mm/s.
Transfer Diverting
Dial in the 65 mm stroke on site for conveyor changeovers, using the needle cushion to quietly stop the diverter without slamming.
Lab Test Actuators
Ideal for compact test rigs where the SUS304 body resists mild corrosion and the adjuster allows rapid 55-65 mm stroke fitting without swapping cylinders.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X65-10 the Right Cylinder?
Choose the 20 mm bore when 157 N push at 0.5 MPa is sufficient; step up to the MFCJ25 (245.3 N) if the load grows. The 10 mm adjustable window and variable air cushion make this cylinder ideal for high-speed changeovers and shock-sensitive trial fits where you need to tune both the end position and deceleration. Mount via LB foot, FA flange or TC trunnion (no SDB).
The air cushion only decelerates the piston near stroke end—it is not a lock. If you need to hold a load vertically on air loss, add an external rod lock or pilot check valve. Because this specific SKU has no -S magnet, position sensing is unavailable; order the -S variant for CMSG/DMSG/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 MFCJ20X65-10 FAQ
This 20 mm bore cylinder has a 1/8" port and delivers 157 N push / 131.9 N pull at 0.5 MPa, and 219.8 N push / 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, this SKU lacks the -S magnet so it cannot take CMSG/DMSG/EMSG switches. The external adjuster only shortens the extend stroke by up to 10 mm; it does not lock or hold the load. The variable air cushion merely decelerates the piston near the end.
