Airtac MFCJ Adjustable Mini Cylinder MFCJ32X70-30S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X70-30S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 70mm stroke, 1/4" 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 MFCJ32X70-30S
Trim the extend stroke by up to 30 mm on site with this adjustable-stroke, variable-cushion mini cylinder. The built-in piston magnet (-S) directly supports CMSG, DMSG and EMSG reed or electronic switches for precise position detection.
Built as a JIS-standard round-body unit with a SUS304 stainless barrel and riveted aluminium covers, it runs at 30-800 mm/s. The 1/4" port and Ø12 mm rod deliver 402.2 N push force at 0.5 MPa. A needle air cushion at each end soaks up high-speed end-of-stroke shock, while the shorter-than-ISO 6432 body saves mounting length. Expect a safe working load around 241 N, or roughly 20.5 kg of vertical lift with a 2:1 margin.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X70-30S Is Used
High-Speed Tool Trial Fits
Dial in the exact 40-70 mm extend position during machining changeovers while the needle cushion absorbs the 402.2 N push impact at rapid traverse speeds.
Adjustable Transfer Stops
Fine-tune the stopping point on the fly for mixed product sizes; the SUS304 barrel handles mild washdown while the -S magnet tracks the part position.
Variable Pusher Stroke
Shorten the extend end by up to 30 mm to push varied carton formats without swapping cylinders, letting the air cushion quietly decelerate the load.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X70-30S the Right Cylinder?
Choose MFCJ32 for moderate thrust, or step up to MFCJ40 if you need the 628.3 N push force at 0.5 MPa. This 32 mm bore provides 402.2 N push and 345.6 N pull at 0.5 MPa, fitting high-speed changeovers where both the end position and the deceleration shock need tuning.
The external adjuster sets the extend end position within a 40-70 mm usable window, but it does not lock the load mid-stroke. If air pressure drops, the piston drifts, so fit an external rod lock or pilot check valve for suspended loads. Mount via LB foot, FA flange or TC trunnion (no SDB), and rely on the -S magnet for your sensors.
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 MFCJ32X70-30S FAQ
This 32 mm bore cylinder features a 1/4" port and a Ø12 mm rod with M10x1.25 male thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical max of 82 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 30 mm on site, giving a usable 40-70 mm window. A variable needle air cushion at both ends decelerates the load near the stroke end for smooth high-speed motion. The -S magnet enables CMSG/DMSG/EMSG sensors.
