Airtac MFCJ Adjustable Mini Cylinder MFCJ32X125-30S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X125-30S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 125mm 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 MFCJ32X125-30S
Tune both the extend end-point and the end-of-stroke shock on-site with this double-acting mini cylinder. The external adjuster shortens the extend stroke by up to 30 mm (usable range 95-125 mm), while the needle variable air cushion at both ends soaks up high-speed impact for smooth, quiet motion. As a JIS-standard round-body unit, its SUS304 stainless barrel and riveted aluminium covers form a compact body that is shorter than an ISO 6432 cylinder for the same bore and stroke, saving valuable mounting length while resisting mild washdown.
Fitted with a 1/4" port, a 12 mm rod and an M10x1.25 male thread, this 32 mm bore variant delivers 402.2 N of push force at 0.5 MPa. The -S suffix denotes a built-in piston magnet for CMSG, DMSG or EMSG switches. For sizing, this bore yields a safe working load of roughly 241 N, meaning it lifts about 20.5 kg vertically with a 2:1 margin.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X125-30S Is Used
High-Speed Diverter Tuning
Perfect for conveyor changeovers where the 30 mm stroke adjuster dials in the exact push distance for different carton sizes, while the variable air cushion halts the 402.2 N thrust smoothly.
Light Milling Clamp
Holds aluminium workpieces during light machining; the 241 N safe working load resists cutting vibration, and the needle cushion prevents shock when clamping at 800 mm/s.
Vertical Package Lift
Lifts about 20.5 kg vertically with a 2:1 safety margin. The SUS304 barrel withstands mild washdown in packing zones, and the CMSG sensor tracks the load reliably.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X125-30S the Right Cylinder?
When choosing between the two available bores, weigh your force needs against speed and space. This 32 mm bore provides 402.2 N push at 0.5 MPa, sitting neatly between the smaller 20/25 mm options (like the 245.3 N MFCJ25) and the larger 628.3 N MFCJ40. If your trial fit or changeover demands higher thrust, step up to the 40 mm bore; if you only need light positioning, the 32 mm saves space and air. Both bores share the 1/4" port and 30-800 mm/s speed range.
The 30 mm adjustable window is perfect for high-speed changeovers where the exact end position and deceleration both need tweaking. Note that the air cushion only decelerates the piston near the end of travel—it is not a lock or brake. If the load must hold position on air loss, install an external rod lock or pilot check valve. Mounting options include LB foot, FA flange and TC trunnion (no SDB), and the -S magnet allows direct sensor mounting.
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 MFCJ32X125-30S FAQ
This 32 mm bore cylinder features a 1/4" port and a 12 mm rod. At 0.5 MPa it pushes with 402.2 N and pulls with 345.6 N. At 0.7 MPa the push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 30 mm on-site (usable range 95-125 mm), and the needle variable air cushion decelerates the piston at both ends. The cushion is not a brake or lock; the cylinder cannot hold position on air loss. The -S magnet allows CMSG, DMSG or EMSG switches for position sensing.
