Airtac MFCJ Adjustable Mini Cylinder MFCJ40X175-75S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ40X175-75S 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 MFCJ40X175-75S
Tune both the extend reach and the end-of-travel shock on-site with this AirTAC adjustable-stroke mini cylinder. The external adjuster shortens the 175 mm extend stroke by up to 75 mm, while the needle variable air cushion at both ends soaks up high-speed impact for smooth deceleration.
Built as a JIS-standard round-body unit with a SUS304 stainless barrel and riveted aluminium covers, it delivers 628.3 N push force at 0.5 MPa through a 1/4 inch port. This compact body is shorter than an ISO 6432 cylinder for the same stroke, and the built-in magnet (-S) supports CMSG, DMSG or EMSG sensors. Based on the 0.5 MPa push rating, it handles a safe working load of roughly 377 N, lifting about 32 kg vertically with a 2:1 margin.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X175-75S Is Used
Press Fit Dialing
Micro-adjust the 175 mm extend stroke by up to 75 mm during press changeovers, using the needle cushion to softly seat 32 kg assemblies without shock.
High-Speed Diverting
Tune the extend endpoint on the fly for varying package sizes while the variable air cushion absorbs the rapid deceleration of heavy 879.6 N push cycles.
Pallet Stop Tuning
Set the exact stopping height for mixed pallet loads and let the dual cushions absorb the impact of 628.3 N push forces at high operating speeds.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X175-75S the Right Cylinder?
Choose the MFCJ40 over the MFCJ32 when you need extra muscle: the 40 mm bore yields 628.3 N push at 0.5 MPa compared to 402.2 N for the 32 mm bore. The 75 mm adjustable window is perfect for high-speed changeovers or trial fits where you must dial in the exact extend position and cushion needle without swapping cylinders.
Remember that the air cushion only decelerates the piston near the end of stroke; it does not lock or hold the load. If air pressure drops, the piston will drift, 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 position sensing.
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 MFCJ40X175-75S FAQ
This 40 mm bore cylinder features a 1/4 inch port and a 16 mm rod. 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, with a theoretical max of 128.1 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 75 mm on-site, while the variable air cushion at both ends decelerates the piston smoothly. The -S magnet allows CMSG, DMSG or EMSG sensors for position feedback.
