Airtac MFCJ Adjustable Mini Cylinder MFCJ40X175-75
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ40X175-75 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 MFCJ40X175-75
Trim the extend stroke by up to 75 mm on site and dial in a needle air cushion at each end to absorb high-speed shocks with the AirTAC MFCJ40X175-75. This double-acting JIS-standard round-body mini cylinder uses a SUS304 stainless barrel and riveted aluminium covers to resist mild washdown while saving mounting length compared to an ISO 6432 unit.
Operating on a 1/4" port with a 16 mm rod, the 40 mm bore delivers 628.3 N of push force at 0.5 MPa. This translates to a safe working load of roughly 377 N, lifting about 32 kg vertically with a 2:1 margin. Note this SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X175-75 Is Used
Package Diverters
Dial in the 75 mm extend window to precisely push 32 kg cartons off a high-speed belt while the variable air cushion prevents end-of-stroke slamming.
Press Fit Tuning
Ideal for trial-and-error press fits where you must fine-tune the extend position on-site and soften the impact of 628.3 N thrust at rapid cycle rates.
Pallet Stops
Adjust the stopper position on the fly for mixed pallet sizes; the needle cushion soaks up the kinetic energy of heavy loads hitting the 175 mm extend limit.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X175-75 the Right Cylinder?
Choose the MFCJ40 over the MFCJ32 when you need serious thrust: the 40 mm bore pushes 628.3 N at 0.5 MPa compared to 402.2 N on the 32 mm bore. The 75 mm adjustable window is ideal for high-speed changeovers or trial fits where the exact 100 to 175 mm extend position and end-of-stroke deceleration both need field tuning. Mount via LB foot, FA flange, or TC trunnion (no SDB). Remember that the air cushion only decelerates the piston near stroke end—it is not a lock. If gravity or air loss might cause drift, fit 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 MFCJ40X175-75 FAQ
This 40 mm bore cylinder features 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, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum of 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet, so it cannot host CMSG, DMSG, or EMSG switches. You must select the -S variant for magnetic sensing. The external adjuster shortens the extend stroke by up to 75 mm but does not lock the piston mid-stroke.
