Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X80U
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X80U is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 80mm 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 MFC20X80U
Delivering 157 N of push force at 0.5 MPa, this double-acting mini cylinder relies on a needle-set variable air cushion at both ends to soak up high-speed end-of-stroke shock. The riveted aluminium covers and SUS304 stainless barrel resist mild corrosion and washdown, while the flat-end U rear cover provides a tidy, flush mount for tight spaces. For the same 20 mm bore and 80 mm stroke, the JIS-standard body is noticeably shorter than an ISO 6432 cylinder, saving valuable machine length without sacrificing the 1/8" port or M8x1.25 male rod thread.
Practically, the 0.5 MPa thrust yields a safe working load of roughly 94 N, meaning it lifts about 8 kg vertically with a 2:1 safety margin. Note this specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG position switches. If air pressure drops, the piston drifts—the cushion only decelerates near stroke end and acts purely as a shock absorber, never a lock.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X80U Is Used
Light-Part Ejection
Cushions the rapid ejection of small moulded parts at 0.5 MPa, using the needle valve to prevent end-of-stroke bounce that could scatter components.
Package Diverting
Ideal for swiftly pushing lightweight cartons off a belt; the flat U cover and compact JIS length fit neatly into tight transfer gaps.
Small Assembly Pressing
Provides the 94 N safe working load needed to seat delicate electronic clips or pins smoothly without crushing the housing.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X80U the Right Cylinder?
When sizing this 20 mm bore unit, step down if your load is light, but if you need more thrust, the next size up is the MFC25, which pushes 245.3 N at 0.5 MPa. Choose this MFC20X80U when operating speeds are high enough that the adjustable needle valve becomes essential for smoothing out the 80 mm travel and protecting the payload from jarring impacts. Because this is a non-magnet SKU, you must select an -S variant if your sequence control requires CMSG or DMSG sensors. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets to suit your frame geometry.
Remember that a standard double-acting cylinder cannot hold a load in place if air supply fails or a valve is centred—the rod will drift. The variable air cushion strictly manages deceleration near the stroke endpoints and provides no braking or locking function. To suspend a load safely during an outage, install an external rod lock or a pilot-operated check valve in the air line.
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 MFC20X80U FAQ
This 20 mm bore cylinder features a 1/8" port and an M8x1.25 male rod thread. 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.
No, this specific SKU does not include the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. The SUS304 stainless build and adjustable air cushion are standard, but the cushion only decelerates the load—it is not a brake.
