Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X160SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X160SU is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 160mm 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 MFC40X160SU
Delivering 628.3 N of push force at 0.5 MPa, this double-acting MFC40X160SU mini cylinder handles heavy loads with precision. A needle-set variable air cushion at both ends absorbs end-of-stroke shock at high speeds, protecting your payload and reducing noise far better than a fixed bumper. The riveted SUS304 stainless barrel and aluminium covers resist mild corrosion and washdown environments.
For the same 40 mm bore and 160 mm stroke, the JIS-standard round-body design is physically shorter than an ISO 6432 cylinder, saving valuable mounting length. Equipped with a 1/4" port, a Ø16 mm piston rod, and a built-in magnet (-S), it supports CMSG, DMSG, and EMSG switches. The U flat-end rear cover simplifies direct mounting. Based on the 0.5 MPa push rating, it handles a safe working load of roughly 377 N, lifting about 32 kg vertically with a 2:1 margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X160SU Is Used
Heavy Package Diversion
Pushes heavy cartons at high speed onto a secondary line; the variable air cushion prevents harsh slams that could damage packaging or shift contents.
Clamp and Press Assembly
Provides 628.3 N of push force at 0.5 MPa to hold components firmly during machining or joining, decelerating smoothly to protect delicate tooling.
Vertical Pallet Lifting
Lifts loads of about 32 kg vertically with a 2:1 safety margin, using the U flat-end cover for stable mounting in compact material handling cells.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X160SU 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 speeds, allowing you to tune the deceleration to prevent end-cap damage.
Remember that the air cushion only decelerates the piston near the stroke end; it does not act as a lock or brake. If air pressure drops, the piston will drift, so install an external rod lock or pilot-operated check valve for secure load holding. This U flat-end model includes the -S magnet for position sensing and accepts LB foot, FA flange, SDB pivot, or TC trunnion mounts.
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 MFC40X160SU FAQ
This 40 mm bore cylinder features a 1/4" port and a Ø16 mm rod. It generates 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, the variable air cushion only decelerates the piston near the end of the stroke and is not a brake. If air pressure drops, the piston will drift. You must use an external rod lock or pilot check valve to hold loads safely. The -S magnet allows CMSG, DMSG, and EMSG sensors for position confirmation.
