Airtac MFCJ Adjustable Mini Cylinder MFCJ20X15-10
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ20X15-10 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 15mm 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 MFCJ20X15-10
Dial in the exact extend end-point on-site with the AirTAC MFCJ20X15-10, a JIS-standard round-body mini cylinder featuring a 10 mm adjustable stroke window and variable air cushioning at both ends. The SUS304 stainless steel barrel and riveted aluminium covers yield a compact body that is shorter than an ISO 6432 unit for the same 20 mm bore and 15 mm stroke, saving valuable mounting length while resisting mild washdown.
Driven by filtered air at 1/8" ports, this double-acting actuator delivers 157 N of push force at 0.5 MPa. The needle cushion soaks up high-speed shock to deliver smooth 30-800 mm/s motion, yielding a safe working load of roughly 94 N. Note that this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG position switches.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X15-10 Is Used
Micro-Clamp Tuning
Ideal for trial-fitting delicate 8 kg workloads where the 10 mm extend adjuster lets you dial in the exact grip position without machining spacers.
Light Diverter Stroke
Use the 157 N push force to deflect small packages on a line, relying on the variable air cushion to silently absorb the 15 mm end-of-stroke impact.
Compact Part Ejection
Fit this shorter-than-ISO-6432 body into tight tooling to eject lightweight parts, tweaking the needle valve to soften high-speed retraction shocks.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X15-10 the Right Cylinder?
When sizing this 20 mm bore against the MFCJ25, compare the actual thrust: this unit pushes 157 N versus 245.3 N for the 25 mm variant at 0.5 MPa. Choose the 20 mm bore for lighter, space-constrained high-speed changeovers where you need to tune both the extend end-point within the 10 mm window and the end-of-stroke shock via the needle cushion.
Mounting options include LB foot, FA flange, and TC trunnion (no SDB or back-cover). Because this non-magnet SKU cannot take a sensor, you will need the -S variant for CMSG/DMSG/EMSG switches. Finally, the air cushion only decelerates the piston near stroke end—it is not a brake; for load holding on air loss, install 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 MFCJ20X15-10 FAQ
This 20 mm bore cylinder features a 1/8" air port and an 8 mm rod. It generates 157 N push / 131.9 N pull at 0.5 MPa, 219.8 N push / 184.7 N pull at 0.7 MPa, and a theoretical maximum of 32 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet and cannot accept CMSG, DMSG, or EMSG switches. You must order the -S variant for sensing. The external adjuster shortens the extend stroke by up to 10 mm, and the variable air cushion decelerates the piston but does not lock the load.
