Airtac MFCJ Adjustable Mini Cylinder MFCJ32X350-50S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X350-50S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 350mm 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 MFCJ32X350-50S
Dial in exact extend lengths on-site with the AirTAC MFCJ32X350-50S, a JIS-standard round-body mini cylinder built from SUS304 stainless steel and riveted aluminium covers. The external adjuster shortens the extend stroke by up to 50 mm within a 300-350 mm usable window, while the needle-set variable air cushion at both ends soaks up high-speed shock. It is a double-acting actuator, not a tie-rod or profile cylinder.
Operating at 30-800 mm/s on a 1/4" port, this 32 mm bore generates 402.2 N of push force at 0.5 MPa. That yields a safe working load of roughly 241 N, or enough to lift about 20.5 kg vertically with a 2:1 margin. The built-in -S magnet supports CMSG, DMSG, and EMSG switches, and the compact MF body is shorter than an ISO 6432 unit for the same stroke, saving valuable mounting length.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X350-50S Is Used
Package Diverter Tuning
Perfect the extend reach of a 350 mm diverter arm by up to 50 mm during line changeovers, using the needle cushion to quietly halt the 402.2 N push stroke at high speed.
Vertical Lift Gate
Lift a 20 kg access gate using the 32 mm bore, relying on the 50 mm adjuster to set the exact open height without repositioning the cylinder mounts.
Press Fit Testing
Execute long-stroke press fits where the variable air cushion absorbs end-of-travel impact, protecting delicate sensors during rapid 300-350 mm extension cycles.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X350-50S the Right Cylinder?
Weigh your force needs between the two available bores: this 32 mm bore provides 402.2 N push at 0.5 MPa, whereas stepping up to the MFCJ40 yields 628.3 N, and dropping to an MFCJ25 offers just 245.3 N. Choose the 32 mm when your changeover requires moderate push force combined with on-site stroke tuning and high-speed cushioning to protect shock-sensitive trial fits.
Mount via LB foot, FA flange, or TC trunnion (there is no SDB or back-cover option). The variable air cushion only decelerates the piston near stroke end—it is not a lock or brake. Because a plain cylinder drifts on air loss, install an external rod lock or pilot-operated check valve if you need to hold a vertical load safely in place.
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 MFCJ32X350-50S FAQ
This 32 mm bore cylinder features a 1/4" port and a 12 mm rod. It delivers 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum force of 82 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 50 mm (usable range 300-350 mm), and the variable air cushion decelerates the piston at both ends. The cushion is not a brake; the cylinder drifts on air loss, so use an external rod lock to hold a load. The -S suffix means it has a magnet for CMSG, DMSG, or EMSG sensors.
