Airtac MFCJ Adjustable Mini Cylinder MFCJ32X300-75
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X300-75 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 300mm 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 MFCJ32X300-75
Tune both the extend end-point and the end-of-stroke shock on site with this JIS-standard round-body mini cylinder. The external adjuster shortens the 300 mm extend stroke by up to 75 mm (usable 225-300 mm), while the needle variable air cushion at both ends soaks up high-speed kinetic energy. A 1/4" port and Ø12 mm rod feed the 32 mm bore, delivering 402.2 N push at 0.5 MPa.
The SUS304 stainless barrel and riveted aluminium covers resist mild washdown corrosion, and the body is shorter than an ISO 6432 cylinder for the same stroke, saving valuable machine length. This non-magnet SKU cannot take a sensor; order the -S variant for CMSG/DMSG/EMSG switches. Based on the 0.5 MPa push force, expect a safe working load around 241 N, lifting about 20.5 kg vertically with a 2:1 margin.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X300-75 Is Used
Changeover Actuation
Dial in the 225-300 mm extend position for different part lengths on a machining line without swapping cylinders, using the 75 mm adjuster to find the exact touch point.
High-Speed Diverting
Push packages at speed with a safe 241 N working load while the variable air cushion prevents harsh slamming at the end of the 300 mm stroke.
Vertical Lift Stops
Lift roughly 20.5 kg vertically and rely on the adjustable needle cushion to deliver a smooth, quiet deceleration at the top of the extend cycle.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X300-75 the Right Cylinder?
Choose between the two available bores based on your payload: the MFCJ32 provides 402.2 N push at 0.5 MPa, while the larger MFCJ40 offers 628.3 N. This 32 mm bore is ideal for medium loads where you need to dial in the exact extend position during changeovers and soften the stop at 800 mm/s. If your force needs are lighter, the MFCJ25 at 245.3 N is the next size down.
Mounting options include LB foot, FA flange, and TC trunnion (no SDB or back-cover). Remember that the air cushion only decelerates the piston near the end of travel; it is not a brake. If the load must hold position on air loss, add an external rod lock or pilot check valve, as the piston will 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 MFCJ32X300-75 FAQ
This 32 mm bore cylinder has a 1/4" port and delivers a push force of 402.2 N and pull of 345.6 N at 0.5 MPa. At 0.7 MPa, push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa at speeds of 30-800 mm/s.
No, this specific SKU lacks the internal magnet, so it cannot take CMSG, DMSG, or EMSG switches. You must order the -S variant for sensing. The 75 mm external adjuster shortens the extend stroke from a 300 mm maximum down to 225 mm, and the variable air cushion decelerates the load at stroke end but does not lock the position.
