Airtac MFCJ Adjustable Mini Cylinder MFCJ20X200-10
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ20X200-10 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 200mm 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 MFCJ20X200-10
Dial in the exact extend end-point on-site with the AirTAC MFCJ20X200-10, a JIS-standard round-body mini cylinder offering a 10 mm adjustable stroke window (usable extend 190-200 mm). The riveted SUS304 stainless barrel and aluminium covers form a compact body that is physically shorter than an ISO 6432 cylinder for the same 20 mm bore and 200 mm stroke, saving valuable mounting length while resisting mild corrosion and washdown.
Driven by filtered air at 1/8" ports, this double-acting actuator generates 157 N of push force at 0.5 MPa and features a needle-set variable air cushion at both ends to absorb high-speed end-of-stroke shock. With a safe working load around 94 N, it lifts about 8 kg vertically with a 2:1 margin. Note this SKU lacks a magnet and cannot take a sensor; the -S variant enables CMSG/DMSG/EMSG switches.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X200-10 Is Used
Lightweight Component Seating
Fine-tune the 10 mm extend window to softly seat delicate electronic components, using the variable air cushion to absorb the 157 N push force at high speed without impact damage.
Package Diverting Stroke
Adjust the extend end-point on the fly for varying carton sizes on a conveyor, letting the needle cushion decelerate the 8 kg vertical lift capacity smoothly at cycle end.
Lab Automation Trial Fits
Ideal for changeovers in lab equipment where the exact 190-200 mm extend position needs empirical tuning on-site, paired with washdown-resistant SUS304 construction.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X200-10 the Right Cylinder?
When sizing these adjustable-stroke units, compare the thrust classes directly: this 20 mm bore provides 157 N push at 0.5 MPa, while stepping up to the MFCJ25 yields 245.3 N. Choose the 20 mm bore for lighter, high-speed changeovers where shock-sensitive trial fits demand both an adjustable end-position and a tunable cushion. Mount via LB foot, FA flange, or TC trunnion (no SDB or back-cover is available on this build).
Remember that the external adjuster only shortens the extend stroke; it is not a mid-stroke lock. Furthermore, the air cushion solely decelerates the piston near the end of travel and does not act as a brake. If the application requires the load to be held securely upon air loss or valve centering, install an external rod lock or pilot-operated 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 MFCJ20X200-10 FAQ
This 20 mm bore double-acting cylinder uses a 1/8" air port and generates 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 specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG magnetic switches. You would need the -S variant for sensing capabilities. The 10 mm adjustable window and variable air cushion function independently of the magnet.
