Airtac MFCJ Adjustable Mini Cylinder MFCJ20X160-20
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ20X160-20 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 MFCJ20X160-20
Dial in exact extend positions on-site with the AirTAC MFCJ20X160-20, a JIS-standard round-body mini cylinder featuring a 20mm adjustable stroke window. This double-acting actuator lets you shorten the extend end from 160mm down to 140mm, while the retract stroke remains full length. A needle-set variable air cushion at both ends soaks up high-speed shock for smooth deceleration.
Built with a SUS304 stainless steel barrel and riveted aluminium covers, it resists mild corrosion and washdowns while offering a shorter mounting envelope than an ISO 6432 cylinder for the same bore and stroke. The 20mm bore uses a 1/8" port and an Ø8mm rod with an M8x1.25 male thread. Delivering 157N push and 131.9N pull at 0.5MPa, it provides a safe working load of roughly 94N and lifts about 8kg vertically with a 2:1 margin. Note this SKU lacks a magnet, so it cannot take position sensors.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X160-20 Is Used
Light-Part Ejection
Tune the extend stroke by up to 20mm to strike plastic parts cleanly at 157N push, using the variable air cushion to prevent bounce at high cycle speeds.
Package Diverting
Adjust the stroke on-site to match varying carton widths, deflecting light boxes smoothly without end-of-stroke shock using the needle cushion.
Lab Automation Fits
Ideal for trial assemblies where the exact 140-160mm extend position is unknown; the SUS304 barrel handles washdown in sensitive environments.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X160-20 the Right Cylinder?
Choose between the compact MFCJ20 and the next size up: the MFCJ25 delivers 245.3N push at 0.5MPa compared to this 20mm bore at 157N. Select the MFCJ20X160-20 when you need precise end-position tuning for high-speed changeovers or shock-sensitive trial fits, as the 20mm adjuster window and variable air cushion handle both simultaneously. Mount via LB foot, FA flange, or TC trunnion (no SDB or back-cover option on this build).
Remember that the air cushion only decelerates the piston near stroke end and the external adjuster sets the end position—neither acts as a mid-stroke lock or brake. If your application must hold a load vertically during air loss or valve centering, the piston will drift; add an external rod lock or pilot-operated check valve. Because this specific code has no -S suffix, it cannot accept CMSG, DMSG, or EMSG magnetic 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 MFCJ20X160-20 FAQ
This 20mm bore cylinder features a 1/8" port, an Ø8mm rod, and an M8x1.25 male thread. It delivers 157N push and 131.9N pull at 0.5MPa, 219.8N push and 184.7N pull at 0.7MPa, with a theoretical max force of 32kgf at 1.0MPa. Operating pressure is 0.15-1.0MPa and speed ranges 30-800mm/s.
The external adjuster shortens the extend stroke by up to 20mm (usable range 140-160mm), while the needle variable air cushion at both ends decelerates the piston near stroke end for smooth high-speed motion. This specific SKU has no -S suffix, meaning it lacks a magnet and cannot accept CMSG, DMSG, or EMSG switches; order the -S variant for sensing.
