Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X300SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X300SCM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 300mm 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 MFC20X300SCM
Delivering 157 N of push force at 0.5 MPa, this double-acting mini cylinder brings needle-adjustable variable air cushioning to high-speed actuation. The riveted SUS304 stainless barrel and aluminium covers resist mild corrosion and washdown, while the CM round-end rear cover supports straightforward mounting. A built-in magnet (-S) enables direct CMSG, DMSG or EMSG sensor tracking.
For the same 20 mm bore and 300 mm stroke, the JIS-standard round body is noticeably shorter than an ISO 6432 cylinder, saving valuable machine space. Tuning the cushion needle at both ends soaks up end-of-stroke shock, protecting the load and cutting noise. Based on the 0.5 MPa push rating, it handles a safe working load of roughly 94 N, lifting about 8 kg vertically with a 2:1 margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X300SCM Is Used
Package Diverting
Routes light parcels at high cycle speeds where the adjustable air cushion silently absorbs the end-of-stroke impact on the 300 mm travel.
Small Component Ejection
Pushes machined parts out of a fixture with a safe 94 N working load, relying on the SUS304 barrel for coolant splash resistance.
Compact Vertical Lift
Raises an 8 kg jig through 300 mm, using the -S magnet and a DMSG switch to confirm elevation without adding excessive length.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X300SCM the Right Cylinder?
When sizing this 20 mm bore unit, step down if your load is very light, or move up to the MFC25 which provides 245.3 N of push force at 0.5 MPa if you need extra thrust. The variable air cushion is essential when cycling at high speeds or moving sensitive masses, as it decelerates the piston smoothly at stroke end. Note that this cushion only slows the piston and does not lock the load; if air pressure drops, the rod will drift, so fit an external rod lock or pilot check valve for vertical holding. The 1/8" port and M8x1.25 male rod thread match standard mini-cylinder hardware.
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 MFC20X300SCM 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 force of 32 kgf at 1.0 MPa.
No, the variable air cushion only decelerates the piston near the stroke end and acts purely as a shock absorber, never as a brake. If air is lost, the rod will drift, so you must install an external rod lock or pilot-operated check valve to hold a vertical load safely.
