Airtac MFCJ Adjustable Mini Cylinder MFCJ20X100-10S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ20X100-10S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 100mm 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 MFCJ20X100-10S
Dial in exact end positions on-site with the AirTAC MFCJ20X100-10S, a JIS-standard round-body mini cylinder featuring a 10 mm adjustable extend window and needle-set variable air cushions at both ends. Driven by a Ø8 mm piston rod with an M8x1.25 male thread and a 1/8" port, it delivers 157 N of push force at 0.5 MPa, yielding a safe working load of roughly 94 N or about 8 kg of vertical lift with a 2:1 margin.
The riveted SUS304 stainless barrel and aluminium covers resist mild corrosion and washdown, while the compact body is explicitly shorter than an ISO 6432 cylinder for the same 20 mm bore and 100 mm stroke. Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG position sensing without further modification.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X100-10S Is Used
Lightweight Pick-and-Place
Handles small electronic components using the 8 kg vertical lift capacity, relying on the 10 mm stroke adjuster to dial in exact placement depth during rapid product changeovers.
High-Speed Diverting
Pushes lightweight cartons at up to 800 mm/s while the variable air cushion soaks up end-of-stroke shock, preventing bounce on fast conveyor sorting lines.
Lab Automation Trial Fits
Ideal for experimental fixturing where the exact 90-100 mm extend position needs on-site tweaking without swapping cylinders, paired with a DMSG sensor for confirmation.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ20X100-10S the Right Cylinder?
Weigh your force needs between the two smallest bores: this MFCJ20 provides 157 N push at 0.5 MPa, whereas stepping up to the MFCJ25 yields 245.3 N. Choose the 20 mm bore for lighter, high-speed changeovers where shock-sensitive trial fits require tuning both the 10 mm extend window and the end-of-stroke cushion. Mount via LB foot, FA flange, or TC trunnion (there is no SDB or back-cover option on this adjustable build).
Remember that the variable air cushion and external adjuster only decelerate the piston and set the end position; they do not function as a lock. If your application must hold a load vertically during air loss or valve centering, add an external rod lock or pilot-operated check valve, as the piston will drift.
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 MFCJ20X100-10S FAQ
This 20 mm bore cylinder features 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 force of 32 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 10 mm on-site, giving a usable extend range of 90-100 mm, while the retract stroke remains full. The needle variable air cushions only decelerate the piston near the ends; they do not lock or hold the load on air loss. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG switches.
