Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X75SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X75SCM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 75mm 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 MFC20X75SCM
Saving mounting length is a hallmark of this JIS-standard round-body mini cylinder, as its riveted SUS304 stainless steel barrel and aluminium covers make it shorter than an ISO 6432 unit for the same 20 mm bore and 75 mm stroke. The double-acting design generates 157 N of push force at 0.5 MPa, making it suitable for compact automation tasks.
A built-in piston magnet (-S) allows integration with CMSG, DMSG or EMSG switches for position sensing, while the CM round-end rear cover completes the assembly. The defining feature is the variable air cushion at both ends: a needle valve lets you dial in the deceleration to absorb high-speed end-of-stroke shock, reducing noise and load impact compared to a fixed bumper. Based on the 0.5 MPa push rating, this actuator 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 MFC20X75SCM Is Used
Light-Part Ejection
Uses the 157 N push force at 0.5 MPa to flick small moulded components out of a press, relying on the tuned air cushion to stop the rod smoothly without slamming.
Package Diverting
Pushes lightweight cartons on a sorting line where the 8 kg vertical lift capacity is plenty, and the CM round-end cover allows flexible rear pivoting.
Small-Part Clamping
Holds delicate electronic housings during an assembly process, using the variable cushion to decelerate gently and prevent cracking at the end of the 75 mm stroke.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X75SCM the Right Cylinder?
When sizing this 20 mm bore actuator, step up to the MFC25 if you need more thrust, as it provides 245.3 N at 0.5 MPa compared to the 157 N offered here; there is no smaller MFC bore, making this the baseline choice for light-force tasks. The adjustable air cushion is essential when cycling at high speeds or moving delicate payloads, letting you tune the end-of-stroke deceleration precisely via the needle.
Note that the cushion only slows the piston near the end of travel and does not function as a brake; if air pressure drops, the piston will drift, so fit an external rod lock or pilot check valve for suspended loads. The 1/8" port matches the bore size, and the included -S magnet means the cylinder is ready for CMSG, DMSG or EMSG sensors without further modification.
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 MFC20X75SCM FAQ
This 20 mm bore double-acting cylinder uses 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, not a brake. If air pressure drops, the piston will drift, so you must use an external rod lock or pilot-operated check valve to hold a suspended load safely.
