Airtac MFCJ Adjustable Mini Cylinder MFCJ32X75-40S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X75-40S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 75mm 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 MFCJ32X75-40S
Dial in exact extend lengths on the factory floor with the AirTAC MFCJ32X75-40S, a JIS-standard round-body mini cylinder built for high-speed precision. The external adjuster shortens the extend stroke by up to 40 mm (usable range 35-75 mm), while the needle-set variable air cushion at both ends soaks up end-of-stroke shock. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdowns, and the body is deliberately shorter than an ISO 6432 cylinder of the same bore and stroke to save mounting space.
Driven by a 12 mm rod and a 1/4" port, this double-acting 32 mm bore generates 402.2 N of push force at 0.5 MPa, peaking at a theoretical 82 kgf at 1.0 MPa. For practical sizing, expect a safe working load around 241 N, or vertical lifts of about 20.5 kg with a 2:1 margin. The -S suffix means a built-in magnet is present, enabling CMSG, DMSG, or EMSG reed or electronic switches for position sensing.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X75-40S Is Used
High-Speed Changeover Dials
Perfect for trial-fit stations needing exact 35-75 mm extend tuning and variable air cushioning to absorb rapid 402.2 N push impacts during format swaps.
Light Machining Clamps
Holds delicate workpieces safely. The 40 mm stroke adjuster prevents over-travel, while the needle cushion decelerates the 32 mm bore smoothly.
Compact Package Diverters
Fits tight conveyor frames thanks to a JIS round body shorter than ISO 6432. The 1/4" port and 241 N safe working load handle light routing tasks.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X75-40S the Right Cylinder?
Weigh your thrust needs between the two available bores: the MFCJ32 delivers 402.2 N push at 0.5 MPa, whereas stepping up to the MFCJ40 provides 628.3 N. Choose this 32 mm bore when your changeovers demand high-speed motion that requires both a 40 mm on-site stroke tweak and needle-cushion tuning to prevent end-of-stroke shock. Note that the air cushion only decelerates the piston near the end of travel—it is not a lock or brake.
If air loss occurs, the piston will drift and cannot hold a load; for vertical or suspended loads, install an external rod lock or pilot-operated check valve. Mounting options include LB foot, FA flange, and TC trunnion (there is no SDB or back-cover option on this adjustable build). Position sensing is ready out of the box thanks to the -S magnet, compatible with CMSG, DMSG, and EMSG 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 MFCJ32X75-40S FAQ
This 32 mm bore, double-acting cylinder uses a 1/4" port and a 12 mm rod. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, or 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical max of 82 kgf at 1.0 MPa. The 75 mm base stroke can be shortened by up to 40 mm on-site, and speed ranges from 30-800 mm/s.
No. The external adjuster only sets the extend end position (35-75 mm), and the variable air cushion only decelerates the piston near stroke end—neither acts as a lock or brake. If air is lost, the piston drifts. For load holding, use an external rod lock or pilot check valve. The -S magnet enables CMSG/DMSG/EMSG sensors.
