Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X20SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X20SCM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 20mm 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 MFC20X20SCM
High-speed strokes run smoother with the AirTAC MFC20X20SCM, a JIS-standard round-body mini cylinder built with a SUS304 stainless barrel and riveted aluminium covers. Its defining feature is the variable air cushion at both ends, letting you dial in a needle valve to absorb end-of-stroke shock and cut noise. For the same 20 mm bore and 20 mm stroke, this riveted body is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length.
Operating as a double-acting unit on a 1/8" port, it generates 157 N of push force at 0.5 MPa. This translates to a safe working load of roughly 94 N, or the ability to lift about 8 kg vertically with a 2:1 safety margin. The -S suffix adds a built-in piston magnet for position sensing, and the CM round-end rear cover supports compact direct mounting.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X20SCM Is Used
Light Part Ejection
Uses the 157 N push force to rapidly eject small plastic parts from a mold, relying on the adjustable air cushion to prevent end-of-stroke impact.
Package Diverting
Pushes lightweight boxes on a conveyor at high speed, where the 8 kg vertical lift capacity and shock absorption ensure smooth transfers.
Compact Sorting Gate
Fits into tight machinery spaces thanks to the shorter-than-ISO-6432 body, actuating a sorting gate with precise position detection via the -S magnet.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X20SCM the Right Cylinder?
If 157 N of push at 0.5 MPa is too much for a delicate task, you would need to step down outside the MFC family, as 20 mm is the smallest bore available. Stepping up to the MFC25 provides 245.3 N at 0.5 MPa if your load demands more thrust. The variable air cushion is essential here for the 30-800 mm/s speed range, decelerating heavy loads smoothly at stroke ends. Note that the cushion only slows the piston near the end of travel, it does not act as a brake or lock. If your application must hold a load vertically during air loss, install an external rod lock or pilot-operated check valve. The included -S magnet pairs directly with CMSG, DMSG, or EMSG switches, while mounting options include LB foot, FA flange, SDB pivot, and TC trunnion.
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 MFC20X20SCM FAQ
This 20 mm bore double-acting cylinder features a 1/8" port and an 8 mm rod. It delivers 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, the variable air cushion only decelerates the piston near the end of the stroke to reduce shock, it does not function as a lock or brake. The piston will drift on air loss, so you need an external rod lock or pilot check valve for load holding. The SUS304 stainless barrel provides mild corrosion resistance for washdown environments.
