Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X180CM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X180CM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 180mm 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 MFC Cushioned Stainless Steel Mini Cylinder MFC40X180CM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore mini cylinder is built for demanding high-speed tasks. The MFC40X180CM features a variable air cushion at both ends, letting you tune a needle valve to absorb end-of-stroke shock, protecting your payload while cutting noise. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown environments.
For the same bore and stroke, this JIS-standard round-body design is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length. It provides a safe working load of roughly 377 N, meaning it can lift about 32 kg vertically with a 2:1 safety margin. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG, or EMSG sensors without switching to an -S variant. The unit features a CM round-end rear cover and a 1/4" port.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X180CM Is Used
Package Diverting
Uses the 879.6 N push force at 0.7 MPa to positively divert heavy cartons on a high-speed sorting line, relying on the tuned air cushion to prevent impact damage at stroke end.
Vertical Material Lowering
Safely lowers 25 kg workpieces with a controlled descent, using the bottom air cushion to decelerate the load smoothly before it reaches the resting position.
Pallet Pressing
Applies consistent downward pressure to settle goods on a pallet, where the SUS304 stainless barrel withstands occasional washdown during facility cleaning.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X180CM the Right Cylinder?
If 628.3 N of push at 0.5 MPa is excessive for your payload, step down to the MFC32, which provides 402.2 N; since 40 mm is the largest available bore in this series, you would need to duplicate cylinders for higher force. The adjustable air cushion is essential when cycling heavy loads at high speeds, as it decelerates the piston smoothly near stroke ends. Remember that this cushion only slows the piston, it does not act as a brake. The cylinder will drift if air pressure drops or a valve is centered, so fit an external rod lock or pilot-operated check valve if you need to hold a suspended load. This non-magnet SKU cannot accept sensors, so choose an -S model if you require position feedback.
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 MFC Cushioned Stainless Steel Mini Cylinder MFC40X180CM FAQ
This 40 mm bore cylinder has a 1/4" port and a 16 mm rod with an M14x1.5 male thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, increasing to 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot host CMSG, DMSG, or EMSG switches. You must select an MFC40X180CM-S variant to enable magnetic sensing. The unit features a CM round-end back cover and uses a variable air cushion at both ends to absorb shock.
