Airtac MFCJ Adjustable Mini Cylinder MFCJ20X200-100S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ20X200-100S 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 MFCJ20X200-100S
Dial in exact extend distances on-site with this double-acting, adjustable-stroke mini cylinder. An external adjuster shortens the extend end by up to 100 mm (yielding a 100-200 mm usable window), while the needle variable air cushion at both ends soaks up high-speed shock for smooth stops.
Built as a JIS-standard round-body unit with a SUS304 stainless barrel and riveted aluminium covers, the body is shorter than an ISO 6432 cylinder for the same 20 mm bore and 200 mm stroke. It pushes with 157 N at 0.5 MPa, giving a safe working load around 94 N or a 2:1 vertical lift of about 8 kg. The -S suffix adds a piston magnet for CMSG/DMSG/EMSG sensors, and the 1/8" port keeps airflow compact.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X200-100S Is Used
Light-Part Ejection
Tune the extend stroke precisely during tooling changeovers to eject sub-8 kg parts without slamming, letting the variable air cushion absorb the 800 mm/s impact.
Transfer Diverter
Adjust the reach on-site to deflect lightweight cartons on a moving belt, relying on the 157 N push force and smooth cushioned stops to prevent product damage.
Lab Test Actuator
Set exact engagement depths for repetitive trial fits in test rigs, using the 100 mm adjuster window to find the optimal position without remachining hard stops.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X200-100S the Right Cylinder?
Weigh this 20 mm bore against the MFCJ25, which steps up to 245.3 N at 0.5 MPa. Choose the 20 mm when your fixture is light—around 94 N safe working load—and you need high-speed changeovers where both the exact extend end-point and end-of-stroke deceleration must be tuned on the fly.
Mounting uses LB foot, FA flange, or TC trunnion (no SDB or back-cover here). Because the -S magnet is present, you can fit CMSG, DMSG, or EMSG switches. Remember the air cushion only decelerates near the end; it is not a brake, so fit an external rod lock or pilot check valve if the load must hold position on air loss.
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 MFCJ20X200-100S FAQ
This 20 mm bore cylinder has a 1/8" port and 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 max of 32 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 100 mm, and the needle variable air cushion decelerates the piston near both ends. The -S magnet allows CMSG/DMSG/EMSG sensors. The cushion is not a lock; the piston drifts on air loss, so use an external rod lock to hold a load.
