Airtac MFCJ Adjustable Mini Cylinder MFCJ20X150-10S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ20X150-10S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 150mm 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 MFCJ20X150-10S
Trimming the extend end by up to 10 mm on site, this double-acting JIS-standard round-body mini cylinder lets you set an exact 140-150 mm forward travel while soaking up high-speed end shock with a needle variable air cushion at both ends. The SUS304 stainless barrel and riveted aluminium covers yield a body that is physically shorter than an ISO 6432 unit for the same 20 mm bore and 150 mm stroke, saving valuable mounting length in tight machine cells.
Delivering 157 N push and 131.9 N pull at 0.5 MPa on a 1/8" port, it handles a safe working load of roughly 94 N or lifts about 8 kg vertically with a 2:1 margin. The -S suffix means a built-in piston magnet is fitted, ready for CMSG, DMSG or EMSG switches to confirm end positions.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X150-10S Is Used
Light-Part Trial Fits
Dial in the 10 mm extend window during prototype changeovers to find the exact 140-150 mm reach for seating delicate 8 kg assemblies without crashing.
High-Speed Diverting
Use the needle variable air cushion to silently decelerate the 157 N push force when rejecting light cartons off a fast belt at up to 800 mm/s.
Washdown Tucking Arms
Rely on the SUS304 stainless barrel to resist mild corrosion while fine-tuning the forward tuck stroke on packaging lines that require regular washdowns.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X150-10S the Right Cylinder?
When sizing this 20 mm bore against the next size up, the MFCJ25 provides 245.3 N push at 0.5 MPa—useful if your payload exceeds the 94 N safe working load. Choose the MFCJ20X150-10S when you need lighter, faster actuation and the ability to dial in the exact extend stop during high-speed changeovers without swapping hard stops.
The external adjuster only sets the end position—it is not a mid-stroke lock, and the air cushion only decelerates the piston rather than holding the load. If gravity or air loss could cause drift, fit an external rod lock or pilot check valve. Mounting options are LB foot, FA flange or TC trunnion (no SDB or back-cover here), and the 1/8" port threads are PT by default with G or NPT(T) optional.
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 MFCJ20X150-10S FAQ
This 20 mm bore cylinder uses 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, with a theoretical max of 32 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 10 mm on site, while the needle variable air cushion decelerates the piston at high speed. It does not hold position on air loss—for that you need an external rod lock. The -S magnet enables CMSG/DMSG/EMSG sensors.
