Airtac MFCJ Adjustable Mini Cylinder MFCJ32X300-30
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X300-30 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 MFCJ32X300-30
Tune both travel and end-of-stroke shock on site with this 32 mm bore, 300 mm stroke mini cylinder. The external adjuster shortens the extend stroke by up to 30 mm (usable range 270-300 mm), while the needle variable air cushion at both ends soaks up high-speed impact. It delivers 402.2 N push force at 0.5 MPa, making the safe working load roughly 241 N.
Built as a JIS-standard round-body unit with a SUS304 stainless barrel and riveted aluminium covers, it is shorter than an ISO 6432 cylinder for the same stroke, saving valuable mounting length. The 1/4" port and M10x1.25 male rod thread simplify integration. Note this SKU lacks a magnet, so it cannot take CMSG/DMSG/EMSG sensors; choose the -S variant for position sensing.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X300-30 Is Used
High-Speed Tooling Changeover
Dial in the 270-300 mm extend position during automated tooling swaps, using the 30 mm adjuster and air cushion to absorb the 402.2 N push impact smoothly.
Package Divert Stroke Tuning
Fine-tune the diverter arm reach on a packaging line, relying on the variable cushion to quietly stop the 241 N working load at high cycle rates.
Lab Automation Trial Fits
Perfect for test fixtures needing exact end-position tuning without changing cylinders, safely lifting 20.5 kg test samples while preventing end-of-stroke shock.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X300-30 the Right Cylinder?
Weighing MFCJ32 against MFCJ40 comes down to force: the 32 mm bore yields 402.2 N push at 0.5 MPa, while the 40 mm bore provides 628.3 N. If your changeover requires less than 245 N, a smaller bore might suffice, but this 32 mm model safely handles about 241 N and lifts around 20.5 kg vertically with a 2:1 margin. Use this adjustable-stroke, cushioned version when you need to dial in the exact extend position and decelerate high-speed masses during trial fits.
Mounting options include LB foot, FA flange, and TC trunnion (no SDB). Because this SKU has no magnet, you cannot mount reed or solid-state switches. Remember that the air cushion only decelerates the piston near the end of travel; it does not lock or hold the load. If air pressure drops, the rod will drift, so fit an external rod lock or pilot check valve for suspended loads.
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 MFCJ32X300-30 FAQ
This 32 mm bore cylinder features a 1/4" port and an M10x1.25 male rod thread. At 0.5 MPa it provides 402.2 N push and 345.6 N pull force. At 0.7 MPa it yields 563 N push and 483.8 N pull. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. The 30 mm adjustable stroke window and variable air cushion function independently of the sensor system.
