Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X300SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X300SU is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 300mm stroke, 1/8" 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 MFC20X300SU
Tuned for high-speed strokes, the MFC20X300SU uses a needle-set variable air cushion at both ends to decelerate the piston smoothly, eliminating the harsh end-of-stroke bang typical of bumper mini cylinders. This JIS-standard round-body unit features a SUS304 stainless barrel and riveted aluminium covers, yielding a body notably shorter than an ISO 6432 cylinder for the same 20 mm bore and 300 mm stroke.
Delivering 157 N of push force at 0.5 MPa, it provides a safe working load of roughly 94 N and can vertically lift about 8 kg with a 2:1 safety margin. The -S suffix equips the piston with a magnet for CMSG, DMSG or EMSG switches, while the U flat-end back cover supports direct mounting. Air connects via a 1/8" port.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X300SU Is Used
Package Diverting
Ideal for swiftly routing small parcels on a 300 mm stroke; the needle-set air cushion halts the 8 kg load gently without jarring the conveyor frame.
Light Assembly Press
Drives a 94 N pressing action for snapping delicate plastic components together, where the SUS304 body resists shop-floor coolant mist.
Compact Tray Sorting
Fits into tight sorting stations thanks to a shorter body than ISO 6432 designs, using the U flat-end cover for flush rear mounting.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X300SU the Right Cylinder?
For lighter payloads, the MFC20X300SU offers a safe working load near 94 N (60% of its 157 N push at 0.5 MPa); if your application demands more thrust, stepping up to the MFC25 provides 245.3 N at 0.5 MPa. The variable air cushion is essential when cycling at high speeds or moving sensitive loads, as it absorbs kinetic energy without harsh impacts.
Because this is a double-acting cylinder, it will drift if air pressure drops or the valve is centred—the cushion only decelerates near stroke end and acts as neither a lock nor a brake. To hold a load securely, install an external rod lock or pilot-operated check valve. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets.
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 MFC20X300SU FAQ
This 20 mm bore cylinder features a 1/8" port and an 8 mm rod. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
Yes, the -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG sensors. However, it cannot hold a load on air loss; the variable air cushion only decelerates the piston near stroke end. Use a pilot check valve for vertical holding.
