Airtac MFCJ Adjustable Mini Cylinder MFCJ32X225-50S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X225-50S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 225mm 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 MFCJ32X225-50S
Dial in exact end positions and absorb high-speed shocks with the AirTAC MFCJ32X225-50S. This JIS-standard round-body mini cylinder features a 50 mm adjustable window, allowing you to shorten the extend stroke on-site from 225 mm down to 175 mm, while the retract remains full. Tuning the needle variable air cushion at both ends ensures quiet deceleration across its 30-800 mm/s operating speed.
Built with a SUS304 stainless steel barrel and riveted aluminium covers, the compact body is shorter than an ISO 6432 cylinder of the same bore and stroke, saving valuable mounting length. The 32 mm bore uses a 1/4" port and a 12 mm rod (M10x1.25 thread), delivering 402.2 N push force at 0.5 MPa. This yields a safe working load of roughly 241 N, lifting about 20.5 kg vertically with a 2:1 margin. The built-in magnet (-S) supports CMSG, DMSG, or EMSG sensors for position feedback.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X225-50S Is Used
Adjustable Tooling Stops
Fine-tune the 225 mm extend stroke down by 50 mm during machine changeovers, using the variable cushion to soften impacts on precision tooling at high speeds.
Dynamic Diverter Arms
Sort packages on a conveyor by adjusting the stroke endpoint on-site to accommodate varying product sizes without swapping the entire cylinder.
Shock-Sensitive Test Rigs
Use the 402.2 N push force and needle-set air cushion to safely decelerate test payloads, preventing damage to delicate components during high-speed trials.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X225-50S the Right Cylinder?
Choose the MFCJ32 over the MFCJ40 (628.3 N push at 0.5 MPa) when your application requires moderate force and high-speed changeovers where both the stroke endpoint and end-of-stroke shock need on-site tuning. The 32 mm bore provides 402.2 N of push force at 0.5 MPa, making it ideal for lighter trial fits and shock-sensitive assemblies.
Mount this cylinder using LB foot, FA flange, or TC trunnion brackets (no SDB or back-cover options exist for this adjustable build). The -S magnet enables CMSG, DMSG, and EMSG switches for electronic or reed feedback. Note that the air cushion and adjuster only decelerate and set the end position; they do not lock the piston. For load holding on air loss, install 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 MFCJ32X225-50S FAQ
This 32 mm bore cylinder features a 1/4" port and a 12 mm rod. At 0.5 MPa it provides 402.2 N push and 345.6 N pull force. At 0.7 MPa it provides 563 N push and 483.8 N pull. The theoretical maximum force is 82 kgf at 1.0 MPa.
The external adjuster shortens the extend stroke by up to 50 mm on-site (usable range 175-225 mm), while the retract stroke remains full. The needle variable air cushion at both ends decelerates the piston near the stroke ends to absorb high-speed shock. The -S suffix indicates a built-in magnet for CMSG, DMSG, or EMSG sensors.
