Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X50CM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X50CM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 50mm 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 MFC20X50CM
Dialing in end-of-stroke deceleration is effortless with the needle-set variable air cushion on this double-acting mini cylinder. Built with a SUS304 stainless barrel and riveted aluminium covers, the JIS-standard round body resists mild corrosion and washdown environments while saving mounting length—it runs physically shorter than an ISO 6432 cylinder for the same 20 mm bore and 50 mm stroke.
Generating 157 N of push force at 0.5 MPa, this 20 mm bore unit handles light payloads smoothly; expect a safe working load around 94 N, or roughly 8 kg of vertical lift with a 2:1 margin. The 1/8" port feeds the 8 mm rod, and the CM round-end rear cover eases flush mounting. Note this SKU lacks the -S magnet, so it cannot accept CMSG, DMSG or EMSG sensors.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X50CM Is Used
Light-Part Ejection
Cushions the stop when kicking small plastic parts out of a press at speed, protecting fragile edges from impact shock.
Flap Folding
Provides the 157 N push needed to fold carton flaps while the needle-set air cushion prevents slamming at stroke end.
Small Package Diverting
Uses the CM round-end cover for tight pivot mounts when sorting lightweight boxes off a conveyor belt without jarring the load.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X50CM the Right Cylinder?
If 157 N at 0.5 MPa feels marginal, step up to the MFC25 (245.3 N); since 20 mm is the smallest MFC bore, there is no smaller option to drop down to. Choose this adjustable-cushion model over a fixed bumper when cycling at high speeds or moving sensitive masses that need shock absorption. Remember the cushion only decelerates near the stroke end—it is not a brake; if you need to hold a load on air loss, add an external rod lock or pilot check valve. For position feedback, select the -S magnet variant instead of this non-magnet SKU to enable switch mounting.
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 MFC20X50CM FAQ
This 20 mm bore cylinder has a 1/8" port and an 8 mm rod. It outputs 157 N push and 131.9 N pull at 0.5 MPa, or 219.8 N push and 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so CMSG, DMSG or EMSG switches cannot be used. You must order the -S variant to enable magnetic sensing. The variable air cushion and SUS304 stainless build remain identical.
