Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X250SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X250SCM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 250mm 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 MFC20X250SCM
Delivering 157 N of push force at 0.5 MPa, this double-acting round-body 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 built-in piston magnet (-S) enables direct mounting of CMSG, DMSG or EMSG switches for position sensing.
For the same 20 mm bore and 250 mm stroke, the JIS-standard body is noticeably shorter than an ISO 6432 cylinder, saving valuable machine space. Driven by a 1/8 inch port and an 8 mm rod, it yields a safe working load of roughly 94 N (about 60 percent of the 0.5 MPa push force) and lifts approximately 8 kg vertically with a 2:1 safety margin. The CM round-end rear cover completes the compact assembly.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X250SCM Is Used
Light-Part Ejection
Uses the 157 N push force to eject small moulded components rapidly, relying on the adjustable air cushion to decelerate the rod softly and prevent marking the parts.
Package Diverting
Pushes lightweight cartons on a sorting line at high speed; the needle-set cushion absorbs the shock at the end of the 250 mm stroke to keep the mechanism quiet.
Lab Sample Handling
Moves delicate test tubes or trays where the SUS304 stainless barrel offers washdown resistance and the smooth cushioning protects fragile glassware from sudden stops.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X250SCM the Right Cylinder?
When sizing this 20 mm bore unit, step down if your load is very light, but if you need more thrust the next size up is the MFC25, which provides 245.3 N of push force at 0.5 MPa compared to this model's 157 N. The variable air cushion is essential if you are cycling at high speeds or moving sensitive masses, as it lets you dial in the exact deceleration to prevent impact damage.
Remember that the air cushion only decelerates the piston near the stroke end; it does not function as a brake or lock. If your application must hold a load vertically during a power or air loss event, fit an external rod lock or a pilot-operated check valve. This specific SKU includes the -S magnet for sensors and uses a CM back cover, so ensure your mounting bracket matches that rear style.
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 MFC20X250SCM FAQ
This 20 mm bore cylinder features a 1/8 inch port and an 8 mm rod. It generates 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.
Yes, the -S suffix indicates a built-in piston magnet for CMSG, DMSG or EMSG sensors. However, the variable air cushion only decelerates the piston near stroke end and does not lock the load; you must add an external rod lock or pilot check valve to hold position on air loss.
