Airtac MFCJ Adjustable Mini Cylinder MFCJ32X30-20
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X30-20 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 30mm 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 MFCJ32X30-20
Trimming the extend stroke by up to 20 mm on-site is effortless with this double-acting mini cylinder, which pairs an external adjuster with a needle variable air cushion at both ends to absorb high-speed shock. The JIS-standard riveted SUS304 stainless round body is shorter than an ISO 6432 cylinder for the same 32 mm bore and 30 mm stroke, saving mounting length while resisting mild washdown corrosion. A 1/4" port and M10x1.25 male rod thread feed the chamber.
Delivering 402.2 N of push force at 0.5 MPa, this unit yields a safe working load of roughly 241 N and lifts about 20.5 kg vertically with a 2:1 margin. The needle cushion decelerates the piston near stroke end for smooth, quiet motion but does not lock the load. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG sensors.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X30-20 Is Used
High-Speed Component Pressing
Dial in the exact 10-30 mm extend contact point on the fly while the variable air cushion softens the 402.2 N impact during rapid automated assembly.
Adjustable Transfer Diverter
Tune the stroke window during product changeovers to deflect varying package sizes, relying on the cushion to prevent end-cap slamming at high cycle rates.
Lab Test Fixture Actuation
Perfect for shock-sensitive trial setups where the 241 N safe working load meets the force requirement and the compact JIS body fits tight prototype frames.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X30-20 the Right Cylinder?
When sizing this adjustable family, compare both bores directly: the 32 mm bore provides 402.2 N push at 0.5 MPa, whereas the larger MFCJ40 delivers 628.3 N. If your changeover requires less force, the MFCJ25 offers 245.3 N. Choose this 32 mm model for high-speed trial fits where you must tune both the end position within the 20 mm window and the end-of-stroke shock simultaneously.
Select LB foot, FA flange or TC trunnion mounts, noting there is no SDB or back-cover option. Remember that the air cushion only decelerates the piston; it will not hold a load on air loss. For vertical or suspended loads that must resist drift, add an external rod lock or pilot-operated check valve. To add sensing later, switch to the -S magnet variant.
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 MFCJ32X30-20 FAQ
This 32 mm bore cylinder uses a 1/4" port and generates 402.2 N push / 345.6 N pull at 0.5 MPa, and 563 N push / 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa. It operates at speeds between 30 and 800 mm/s.
The external adjuster shortens the extend stroke by up to 20 mm, giving a usable 10-30 mm extend window while retract remains full. The needle variable air cushion decelerates the piston near the end but does not act as a brake. This specific SKU has no magnet (-S), so it cannot accept CMSG, DMSG or EMSG sensors.
