Airtac MFCJ Adjustable Mini Cylinder MFCJ32X75-20S
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X75-20S is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 75mm 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 MFCJ32X75-20S
Dial in exact extend lengths and tame high-speed shocks with the AirTAC MFCJ32X75-20S, a JIS-standard round-body mini cylinder. The external adjuster shortens the extend stroke by up to 20 mm on-site, giving a usable 55-75 mm window, while the needle-set variable air cushion at both ends soaks up end-of-stroke impact. A 32 mm bore delivers 402.2 N of push force at 0.5 MPa.
Built with a SUS304 stainless steel barrel and riveted aluminium covers, this double-acting unit resists mild corrosion and washdown. It is shorter than an ISO 6432 cylinder for the same bore and stroke, saving mounting length. The -S suffix provides a built-in magnet for CMSG, DMSG, or EMSG sensors. Based on the 402.2 N push figure, expect a safe working load of about 241 N, lifting roughly 20.5 kg vertically with a 2:1 margin. The 1/4" port and M10x1.25 male rod thread ensure solid pneumatic integration.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X75-20S Is Used
Changeover Trial Fits
Perfect for packaging lines needing rapid format changes, using the 20 mm adjuster to fine-tune the 55-75 mm extend position during high-speed product transfers.
Shock-Sensitive Diverting
Handles light item diverting at up to 800 mm/s, relying on the variable air cushion to bring the 402.2 N thrust to a smooth, quiet stop without slamming.
Vertical Lift Stops
Ideal for lifting 20.5 kg loads in pick-and-place modules, where the needle cushion absorbs the downward impact at the end of every retract stroke.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X75-20S the Right Cylinder?
When sizing this adjustable family, compare both real bores: the MFCJ32 delivers 402.2 N push at 0.5 MPa, while stepping up to the MFCJ40 yields 628.3 N. Choose the 32 mm bore for lighter, high-speed changeovers where you need to tune both the extend end position and the end-of-stroke shock. If your trial fit demands more thrust, the 40 mm bore is the next step.
Remember that the air cushion only decelerates the piston near the end of stroke; it is not a lock or brake. If air loss occurs, the piston will drift, so add an external rod lock or pilot check valve for suspended loads. Mounting options include LB foot, FA flange, and TC trunnion (no SDB). Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG switches for position sensing.
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 MFCJ32X75-20S FAQ
This 32 mm bore cylinder features a 1/4" port and a 12 mm rod with an M10x1.25 male thread. It generates 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 20 mm on-site, yielding a 55-75 mm usable window, while the retract remains full. The variable air cushion at both ends decelerates the piston near stroke end to reduce shock, but it is not a brake. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG sensors.
