Airtac MFCJ Adjustable Mini Cylinder MFCJ40X60-50
The AirTAC Airtac MFCJ Adjustable Mini Cylinder MFCJ40X60-50 is a genuine double acting, adjustable stroke + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 60mm 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 MFCJ40X60-50
Tune both the extend reach and end-of-stroke shock on site with this AirTAC MFCJ40X60-50 cylinder. An external adjuster shortens the extend stroke by up to 50 mm, while a needle variable air cushion at each end soaks up high-speed impact for quiet motion. It is a JIS-standard round-body mini built with a SUS304 stainless barrel and riveted aluminium covers, giving you a shorter mounting envelope than an ISO 6432 unit while resisting mild washdown.
Fitted with a 16 mm rod, an M14x1.5 male thread, and a 1/4" port, this double-acting 40 mm bore generates 628.3 N of push force at 0.5 MPa. That translates to a safe working load of roughly 377 N, or lifting about 32 kg vertically with a 2:1 margin. Note this specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X60-50 Is Used
Adjustable Press Fit
Dial in the exact 10 to 60 mm extend reach for pressing bearings, using the variable cushion to prevent harsh impact at high speed.
Changeover Diverter
Re-tune the extend endpoint on the fly during product line changeovers, absorbing the shock of high-speed diverting movements.
Light Milling Stop
Set a precise material stop on a machining table, leveraging the 628.3 N push force to position heavier workpieces reliably.
Is the Airtac MFCJ Adjustable Mini Cylinder MFCJ40X60-50 the Right Cylinder?
When sizing between the two available bores, the MFCJ40 delivers 628.3 N push at 0.5 MPa compared to 402.2 N on the MFCJ32, making the 40 mm bore the right call for heavier changeovers where you also need to dial in the exact extend position. The 50 mm adjustable window is ideal for trial fits where the final reach and end-of-stroke shock both need tuning. Mount via LB foot, FA flange, or TC trunnion (there is no SDB or back-cover option). Remember the air cushion only decelerates the piston near the end of travel; it is not a brake. If the load must stay put after air loss, add 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 MFCJ40X60-50 FAQ
This 40 mm bore double-acting cylinder uses a 1/4" port and a 16 mm rod. It delivers 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum of 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. The external adjuster only shortens the extend stroke; it does not lock the piston mid-stroke.
