Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X100CM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X100CM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 100mm 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 MFC40X100CM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting mini cylinder handles heavy-duty actuation with precision. The MFC40X100CM features a JIS-standard round-body construction with a SUS304 stainless barrel and riveted aluminium covers, offering excellent resistance to mild corrosion and washdown environments. For the same bore and stroke, this riveted body is notably shorter than an ISO 6432 cylinder, saving valuable mounting length without requiring a tie-rod or profile design.
A defining feature is the variable air cushion at both ends, which uses a needle valve to absorb end-of-stroke shock at high speeds, protecting the load and reducing noise. Operating at speeds of 30-800 mm/s with a 1/4" port and an M14x1.5 male rod thread, it provides a safe working load of roughly 377 N. This translates to lifting about 32 kg vertically with a 2:1 safety margin. The rear end uses a CM round cover, and because this specific SKU lacks the -S suffix, it cannot accept CMSG, DMSG, or EMSG magnetic switches.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X100CM Is Used
Heavy Package Diversion
Pushes heavy cartons at high cycle rates on a sorting line, using the variable air cushion to silently absorb the 628.3 N impact at stroke end.
Press Ejection System
Ejects dense machined parts from a fixture, relying on the SUS304 stainless barrel to resist mild coolant spray while handling the 32 kg load.
Pallet Stopper Gate
Acts as a high-speed stop gate for loaded pallets, where the compact JIS body saves mounting space and the needle-set cushion halts the rod smoothly.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X100CM the Right Cylinder?
When sizing this 40 mm bore, step down to the MFC32 if your application only requires 402.2 N of push force at 0.5 MPa, as no larger MFC bore exists for loads exceeding the 628.3 N provided here. The variable air cushion is essential when cycling heavy masses at high velocities, allowing you to tune the deceleration and prevent harsh impacts. Remember that the cushion only decelerates the piston near the stroke end; it does not function as a lock or brake. If the machine loses air pressure, the piston will drift, so you must fit an external rod lock or pilot-operated check valve to hold a suspended load safely.
For mounting flexibility, you can pair the CM round rear cover with LB foot brackets, FA flanges, SDB pivot blocks, or TC trunnion joints. Because this model has no internal magnet, position sensing is impossible; you must select an -S variant to use CMSG, DMSG, or EMSG switches.
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 MFC40X100CM FAQ
This 40 mm bore cylinder features a 1/4" port and an M14x1.5 male rod 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, because this SKU lacks the -S suffix, it has no internal magnet and cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for position sensing. Additionally, its variable air cushion only decelerates the piston near the stroke end and does not lock the load on air loss.
