Airtac MFCJ Adjustable Mini Cylinder MFCJ40X75-10S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ40X75-10S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø40mm 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 MFCJ40X75-10S
Tune the extend end by up to 10 mm on site and set a needle air cushion at each end to absorb high-speed shock with the AirTAC MFCJ40X75-10S. This double-acting, JIS-standard round-body mini cylinder features a SUS304 stainless barrel and riveted aluminium covers, yielding a shorter mounting envelope than an ISO 6432 unit for the same 40 mm bore and 75 mm stroke. The built-in piston magnet (-S) supports CMSG, DMSG and EMSG switches.
Delivering 628.3 N push and 527.8 N pull at 0.5 MPa through a 1/4" port, this 16 mm rod unit handles robust cycling. The variable cushion soaks up end-of-stroke energy without acting as a lock; the piston drifts on air loss, so fit an external rod lock for held loads. Expect a safe working load around 377 N or vertical lifts of about 32 kg with a 2:1 margin.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X75-10S Is Used
High-Speed Diverting
Use the 628.3 N push force and variable air cushion to snap packages across a transfer at high speed without slamming the end cap.
Tooling Trial Fits
Dial in the extend stroke within the 10 mm window during initial tooling setups, letting the needle cushion absorb the shock of test strokes.
Vertical Lift Stops
Lift roughly 32 kg vertically with a 2:1 margin; the SUS304 barrel resists washdown moisture in dispatch zones while the cushion softens the top stop.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X75-10S the Right Cylinder?
Weigh the MFCJ40 against the MFCJ32 for your drive needs. The 40 mm bore pushes 628.3 N at 0.5 MPa, while the 32 mm bore yields 402.2 N. Choose the 40 mm bore for heavier indexing and use the 10 mm external adjuster to dial in the exact extend position during trial fits or changeovers. The needle air cushion handles speeds from 30 to 800 mm/s, decelerating the load smoothly at the ends.
Mounting options include LB foot, FA flange and TC trunnion (no SDB or back-cover code). The -S magnet enables CMSG, DMSG and EMSG sensors for position confirmation. Remember that the cushion only decelerates; it does not brake or hold the load on air loss, so install a pilot check valve if you need to prevent 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 MFCJ40X75-10S FAQ
This 40 mm bore cylinder has a 1/4" port and a 16 mm rod with an M14x1.5 male thread. It pushes 628.3 N and pulls 527.8 N at 0.5 MPa. At 0.7 MPa it pushes 879.6 N and pulls 738.9 N. The theoretical maximum force is 128.1 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 65 to 75 mm; retract remains full. The variable air cushion at both ends decelerates the piston near the stroke ends for smooth stops. The -S suffix means it has a built-in magnet for CMSG, DMSG and EMSG sensors.
