Airtac MFCJ Adjustable Mini Cylinder MFCJ20X160-75
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ20X160-75 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 160mm 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 MFCJ20X160-75
Trim the extend stroke by up to 75 mm on site with this adjustable-stroke, variable-cushion mini cylinder, dropping the usable extension to 85 mm from a 160 mm maximum. The riveted SUS304 stainless round body and aluminium covers form a JIS-standard unit that is physically shorter than an ISO 6432 cylinder of the same bore and stroke, saving valuable mounting length while resisting mild washdown corrosion.
Driven by filtered air through a 1/8" port, the Ø8 mm rod delivers 157 N of push force at 0.5 MPa. That translates to a safe working load of roughly 94 N, or lifting about 8 kg vertically with a 2:1 margin. Needle-set air cushions at both ends soak up high-speed shock for smooth 30-800 mm/s operation. Note this SKU lacks a magnet, so it cannot take CMSG, DMSG or EMSG switches.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X160-75 Is Used
Light Part Trial Fits
Dial in the exact extend position within the 75 mm window for delicate 8 kg assembly probes, relying on the variable air cushion to prevent harsh end impacts.
High-Speed Diverters
Sort small goods at speed using the 157 N push force, fine-tuning the retract cushion to absorb shock during rapid 30-800 mm/s changeovers.
Adjustable Test Fixtures
Set custom extension lengths from 85 to 160 mm for lab equipment, using the compact JIS-standard stainless body to fit tight test rigs.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X160-75 the Right Cylinder?
Weigh the MFCJ20 against the MFCJ25 by force: the 20 mm bore gives 157 N push at 0.5 MPa, while the 25 mm bore steps up to 245.3 N. Pick the 20 mm for lighter, high-speed changeovers where you need to tune both the extend end-point within the 75 mm window and dial in the end-of-stroke cushioning to protect shock-sensitive trial fits. Mounting uses LB foot, FA flange or TC trunnion brackets; there is no SDB or back-cover option on this adjustable build.
The variable air cushion only decelerates the piston near the stroke end—it is not a lock or brake. If the load must be held during air loss or when a valve is centred, the piston will drift, so fit an external rod lock or pilot-operated check valve. Because this specific SKU has no -S magnet, position sensing is not possible; choose the -S variant if you need CMSG, DMSG or EMSG switches.
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 MFCJ20X160-75 FAQ
This 20 mm bore cylinder uses 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 maximum of 32 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 75 mm on site, giving a usable extension of 85-160 mm. This specific SKU has no -S magnet, so it cannot accept CMSG, DMSG or EMSG switches; you need the -S variant for sensing.
