Airtac MFCJ Adjustable Mini Cylinder MFCJ32X300-30S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X300-30S 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 MFCJ32X300-30S
Tune your extend end-position on-site with the AirTAC MFCJ32X300-30S, a JIS-standard round-body mini cylinder featuring a 30mm adjustable stroke window and a needle-set variable air cushion at both ends. The SUS304 stainless steel barrel and riveted aluminium covers yield a shorter mounting envelope than an ISO 6432 unit, while resisting mild washdown corrosion.
Driven by a 32mm bore and a 1/4 inch port, this double-acting actuator delivers 402.2N of push force at 0.5MPa. The integrated -S magnet enables CMSG, DMSG, or EMSG sensor switches for position feedback. Factoring a 2:1 safety margin, it provides a safe working load of roughly 241N, lifting about 20.5kg vertically.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X300-30S Is Used
High-Speed Diverting
Ideal for conveyor changeovers where the 30mm stroke adjuster dials in the exact 270-300mm push distance for product routing, while the variable air cushion absorbs high-speed impact.
Trial-Fit Clamping
Perfect for shock-sensitive machining fixtures; the 402.2N push force secures parts, and the needle cushion softens the end-of-stroke deceleration during rapid clamping.
Vertical Lift Stops
Suited for light vertical lifting up to 20.5kg with a 2:1 margin, allowing operators to fine-tune the extend stop precisely without re-engineering the mount.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X300-30S the Right Cylinder?
When sizing this adjustable-stroke family, compare both bores directly: the 32mm bore yields 402.2N push at 0.5MPa, whereas stepping up to the MFCJ40 provides 628.3N. Choose the 32mm variant for standard trial-fit changeovers where both the end-of-stroke shock and the 270-300mm extend length need on-site tuning via the 30mm window.
Mounting options include LB foot, FA flange, and TC trunnion (SDB is unavailable). Note that the air cushion only decelerates the piston near stroke end; it does not function as a brake. If your application must hold a load on air loss, install 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 MFCJ32X300-30S FAQ
This 32mm bore cylinder features a 1/4 inch port and a 12mm rod. It generates 402.2N push and 345.6N pull at 0.5MPa, or 563N push and 483.8N pull at 0.7MPa. The theoretical maximum force is 82kgf at 1.0MPa.
The external adjuster shortens the extend stroke by up to 30mm on-site (usable range 270-300mm), while the variable air cushion decelerates the piston at both ends. The -S suffix indicates a built-in magnet for CMSG, DMSG, or EMSG switches.
