Airtac MFCJ Adjustable Mini Cylinder MFCJ32X250-50
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ32X250-50 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 250mm 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 MFCJ32X250-50
Dial in exact end positions and absorb high-speed shock with this JIS-standard round-body mini cylinder. The external adjuster shortens the extend stroke by up to 50 mm on site, while the needle-set variable air cushion at both ends ensures smooth deceleration. It features a SUS304 stainless barrel and riveted aluminium covers, offering a shorter mounting length than an ISO 6432 unit for the same 32 mm bore and 250 mm stroke.
Operating at 30-800 mm/s via a 1/4" port and 12 mm rod, it delivers 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. Note this SKU lacks the -S magnet, so it cannot accept CMSG/DMSG/EMSG sensors.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X250-50 Is Used
Sorter Diverter Tuning
Perfect for high-speed package routing where the 50 mm extend adjuster fine-tunes the pusher reach, and the air cushion absorbs the 402.2 N impact at stroke end.
Press Fit Commissioning
Ideal for trial assembly stations needing precise 200-250 mm extend positioning. The needle cushion prevents shock damage to delicate components during rapid cycles.
Pallet Stop Adjustment
Deploy on conveyors to halt pallets. The 241 N safe working load handles moderate weights, while the adjustable stroke accommodates varying pallet dimensions.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ32X250-50 the Right Cylinder?
Choose between the two available bores based on your force requirements: the MFCJ32 provides 402.2 N push at 0.5 MPa, while the larger MFCJ40 offers 628.3 N. This 32 mm bore is ideal for medium-duty tasks. The 50 mm adjustable window is perfect for changeovers where the exact 200-250 mm extend position and end-of-stroke shock both need on-site tuning.
Mount using LB foot, FA flange, or TC trunnion (no SDB or back-cover). Remember that the air cushion only decelerates the piston near stroke end; it does not act as a brake. If you need to hold a load vertically during air loss, add an external rod lock or pilot check valve. For position sensing, select the -S magnet variant instead of this base model.
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 MFCJ32X250-50 FAQ
This 32 mm bore cylinder features a 1/4" port and a 12 mm rod. 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 of 82 kgf at 1.0 MPa.
This specific SKU lacks the -S magnet, so it cannot accept CMSG/DMSG/EMSG switches. The external adjuster shortens the extend stroke by up to 50 mm on site, and the variable air cushion at both ends is needle-set to manage high-speed shock.
