Airtac MFCJ Adjustable Mini Cylinder MFCJ32X300-100
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X300-100 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 MFCJ32X300-100
Dial in exact end positions on-site with the AirTAC MFCJ32X300-100, a JIS-standard round-body mini cylinder featuring a 100 mm adjustable extend window and variable air cushions at both ends. The SUS304 stainless barrel and riveted aluminium covers yield a shorter mounting envelope than an ISO 6432 unit, resisting mild washdown corrosion while saving space. A 1/4" port and 12 mm rod handle a 402.2 N push force at 0.5 MPa.
This double-acting actuator lets you shorten the nominal 300 mm extend stroke by up to 100 mm, while the needle cushions soak up high-speed end-of-travel shock. It delivers a safe working load of roughly 241 N, lifting about 20.5 kg vertically with a 2:1 margin. Note this specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X300-100 Is Used
Adjustable Tooling Strokes
Fine-tune the extend position by up to 100 mm during machine changeovers, letting a 402.2 N push force seat delicate components without repeated mechanical re-shimming.
High-Speed Diverters
Use the variable air cushion to silently halt the 300 mm stroke at rapid cycling speeds, absorbing kinetic energy at the end of travel without slamming the riveted covers.
Vertical Lift Gates
Lift roughly 20.5 kg of lightweight gating using the 0.5 MPa thrust, relying on the external adjuster to set the exact opening height for varying pallet sizes.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X300-100 the Right Cylinder?
When sizing this series, compare both bores: the MFCJ32 provides 402.2 N push at 0.5 MPa, whereas the larger MFCJ40 delivers 628.3 N. Choose the 32 mm bore for lighter, high-speed changeovers where shock-sensitive trial fits demand both a 100 mm stroke adjustment and precise needle cushioning. If your application needs position feedback, select the -S magnet variant instead, as this base SKU cannot host a sensor. Mount via LB foot, FA flange, or TC trunnion.
Remember that the air cushion only decelerates the piston near the stroke end; it is not a brake. The cylinder will drift and fail to hold a load on air loss or when the valve is centred. For suspended or vertical loads that must remain fixed during a pressure drop, install an external rod lock or a pilot-operated 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 MFCJ32X300-100 FAQ
This 32 mm bore cylinder features a 1/4" port and a 12 mm rod. It generates a push force of 402.2 N and a pull force of 345.6 N at 0.5 MPa. At 0.7 MPa, the push is 563 N and the pull is 483.8 N. The theoretical maximum force is 82 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 choose the -S variant for position sensing. The external adjuster physically shortens the extend stroke by up to 100 mm, but it is not a mid-stroke lock.
