Airtac MFCJ Adjustable Mini Cylinder MFCJ40X175-100
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ40X175-100 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 175mm 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 MFCJ40X175-100
Dial in exact end positions and absorb high-speed impact with the AirTAC MFCJ40X175-100, a JIS-standard round-body mini cylinder built with a SUS304 stainless barrel and riveted aluminium covers. The external adjuster shortens the extend stroke by up to 100 mm on-site, giving a usable 75-175 mm extend window, while needle-set variable air cushions at both ends soak up end-of-stroke shock. This 40 mm bore runs on a 1/4" port and delivers 628.3 N of push force at 0.5 MPa.
In practical terms, this bore size yields a safe working load of roughly 377 N, or enough to lift about 32 kg vertically with a 2:1 safety margin. The riveted stainless steel body is shorter than an equivalent ISO 6432 cylinder, saving valuable mounting length while resisting mild washdown corrosion. Note this specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG position switches.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X175-100 Is Used
Prototype Stroke Tuning
Ideal for R&D fixtures where the exact 75-175 mm extend length needs on-the-fly dialing via the 100 mm adjuster during high-speed trial fits.
Heavy Diverter Arm
Pushes heavier product lanes with 628.3 N force at 0.5 MPa, using the variable air cushion to softly stop the 40 mm bore at high cycle rates.
Dynamic Carton Flap Folder
Handles variable carton depths by shortening the extend stroke on-site, while the needle cushion absorbs the shock of rapid 800 mm/s folding motions.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X175-100 the Right Cylinder?
When sizing an adjustable-stroke cylinder, compare the real thrust: this MFCJ40 delivers 628.3 N push at 0.5 MPa, whereas the smaller MFCJ32 provides 402.2 N. Choose the 40 mm bore if your changeover fixture or trial-fit assembly requires moving heavier payloads up to the 32 kg vertical lift threshold. The 100 mm adjust window is ideal for prototyping cells where the exact extend length is unknown, and the variable air cushion lets you tune deceleration for 30-800 mm/s cycling without metal-banging shock.
Mounting options include LB foot, FA flange and TC trunnion (there is no SDB or back-cover option on this build). Because this is a non-magnet SKU, you cannot mount reed or solid-state sensors; if you need position feedback, specify an -S variant. Remember the air cushion only decelerates the piston near the stroke end—it is not a brake. If gravity or air loss could cause the load to drift, install an external rod lock or pilot check valve.
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 MFCJ40X175-100 FAQ
This 40 mm bore double-acting cylinder uses a 1/4" port and a 16 mm rod with an M14x1.5 male thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, or 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum force is 128.1 kgf at 1.0 MPa. The base stroke is 175 mm, but the external adjuster can shorten the extend end by up to 100 mm.
No, this specific SKU does not have the -S magnet option, so it cannot accept CMSG, DMSG or EMSG switches. The variable air cushion at both ends only decelerates the piston near the end of stroke to reduce shock; it is not a lock or brake. The piston will drift on air loss, so use an external rod lock or pilot check valve if you need to hold a suspended load.
