Airtac MFCJ Adjustable Mini Cylinder MFCJ20X10-10
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ20X10-10 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 10mm 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 MFCJ20X10-10
Trim the extend stroke by up to 10 mm on site with the AirTAC MFCJ20X10-10, a JIS-standard round-body mini cylinder built for fine-tuning. A needle variable air cushion at both ends absorbs high-speed shock for quiet motion. This double-acting actuator uses a SUS304 stainless barrel and riveted aluminium covers, resisting mild corrosion while saving mounting length compared to an ISO 6432 unit.
Delivering 157 N of push force at 0.5 MPa through a 1/8" port, it yields a safe working load of roughly 94 N and lifts about 8 kg vertically with a 2:1 margin. The external adjuster sets the end position without acting as a mid-stroke lock. Note this SKU lacks a magnet, so it cannot take a CMSG, DMSG, or EMSG sensor.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X10-10 Is Used
Precision Trial Fits
Dial in the exact extend position within the 10 mm window during light-force assembly trial fits, protecting delicate parts with the variable air cushion.
High-Speed Diverting
Smoothly divert small packages on a conveyor at up to 800 mm/s, relying on the needle cushion to decelerate the 157 N push force quietly.
Lab Automation
Actuate compact lab mechanisms where the SUS304 stainless barrel resists mild washdown and the short JIS body saves valuable space.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X10-10 the Right Cylinder?
Choose the MFCJ20 over the MFCJ25 when 157 N of push force at 0.5 MPa is sufficient, as the larger bore provides 245.3 N. The 10 mm adjustable window is ideal for high-speed changeovers or trial fits where the exact extend position and end-of-stroke shock both need tuning. Mounting options include LB foot, FA flange, and TC trunnion. The piston drifts on air loss, so specify an external rod lock or pilot check valve for held loads.
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 MFCJ20X10-10 FAQ
This 20 mm bore cylinder features a 1/8" port and an Ø8 mm rod. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical max of 32 kgf at 1.0 MPa.
No, this specific SKU lacks the internal magnet required for sensing. You must select the -S variant to use CMSG, DMSG, or EMSG switches. The external adjuster shortens the extend stroke by up to 10 mm but does not lock the piston mid-stroke.
