Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X50CA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X50CA 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 MFC20X50CA
Damping high-speed strokes in tight machinery, the AirTAC MFC20X50CA is a JIS-standard round-body mini cylinder built with a SUS304 stainless barrel and riveted aluminium covers. The double-acting piston uses a two-way oil-retaining seal and a fixed anti-impact pad at the front cover. A variable air cushion at both ends lets you turn a needle to soak up end-of-stroke shock, protecting the load and cutting noise versus a simple bumper mini. For the same 20 mm bore and 50 mm stroke, this riveted body is notably shorter than an ISO 6432 cylinder, saving valuable mounting length.
In the 20 mm class, this actuator generates 157 N of push and 131.9 N of pull at 0.5 MPa, peaking at a theoretical 32 kgf at 1.0 MPa. It ports via 1/8" threads and carries an M8x1.25 male rod thread on its 8 mm piston rod. Based on the 0.5 MPa push force, it handles a safe working load of roughly 94 N, meaning it lifts about 8 kg vertically with a 2:1 margin. The stainless build resists mild corrosion and washdown. Note this specific SKU lacks a magnet, so it cannot take a CMSG, DMSG, or EMSG sensor without upgrading to an -S variant.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X50CA Is Used
Small Parts Sorting
Ideal for rapidly deflecting light components on a conveyor; the dual variable air cushions absorb the impact when cycling at high speeds to prevent premature wear.
Carton Flap Folding
Provides the precise 157 N push needed to tuck flaps on small packaging lines, with the CA pivot allowing the rod to align naturally with the moving cardboard.
Light Clamping Jigs
Holds delicate workpieces securely during machining or gluing, using the 8 kg vertical lift capacity safely without crushing the component.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X50CA the Right Cylinder?
When sizing this 20 mm bore against the rest of the MFC family, step down if your load is very light, or move up to the MFC25 if you need more force—the MFC25 delivers 245.3 N of push at 0.5 MPa compared to the 157 N provided here. The variable air cushion is essential if you are running the cylinder near its 800 mm/s speed limit or moving a heavy mass, as it decelerates the piston smoothly. Keep in mind the cushion only slows the stroke end; it does not lock the rod. If your application must hold a vertical load on air loss, add an external rod lock or pilot-operated check valve.
This MFC20X50CA model features a CA rear pivot cover, making it suitable for clevis or trunnion-style mounting arrangements that accommodate rod side-play. Because this exact SKU is non-magnetic, you cannot mount position switches to it. If your sequencing requires end-of-stroke detection, select the -S magnet option to enable CMSG, DMSG, or EMSG sensors.
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 MFC20X50CA FAQ
This 20 mm bore cylinder features a 1/8" port and an M8x1.25 male rod thread. It outputs 157 N push and 131.9 N pull at 0.5 MPa, increasing to 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 it cannot support CMSG, DMSG, or EMSG switches. You must select an MFC model with the -S suffix to enable magnetic sensing. The variable air cushion and SUS304 stainless barrel are present, but the cushion only decelerates the load and does not brake or hold it.
