Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X75SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X75SCA 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 MFC20X75SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting 20 mm bore mini cylinder relies on a needle-set variable air cushion at both ends to soak up high-speed end-of-stroke shock. The riveted SUS304 stainless barrel and aluminium covers resist mild corrosion and washdown. For the same bore and stroke, the JIS-standard round body is shorter than an ISO 6432 cylinder, saving valuable mounting length.
Equipped with an internal magnet (-S) for CMSG, DMSG or EMSG switches, and a CA rear pivot cover, it handles a 75 mm stroke efficiently. The 1/8" port feeds the 8 mm rod, yielding a safe working load of roughly 94 N or a vertical lift of about 8 kg with a 2:1 margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X75SCA Is Used
Light Part Ejection
Uses the 94 N safe working load to push small plastic components out of a mould, relying on the adjustable air cushion to soften the end stroke.
Package Diverting
Sorts light cartons on a line where the 8 kg vertical lift capacity and 75 mm stroke provide just enough reach to nudge items onto a secondary track.
Small Part Pressing
Seats lightweight bearings or clips with a controlled 157 N force, using the needle cushion to prevent harsh impact on the assembly.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X75SCA the Right Cylinder?
If 94 N is insufficient, step up to the MFC25 which provides 245.3 N at 0.5 MPa; there is no smaller MFC bore, so this 20 mm model is the compact baseline. Dial in the variable air cushion when cycling at high speeds or moving delicate loads to prevent impact damage. Note that the cushion only decelerates the piston near stroke end and does not act as a lock; if you need to hold a vertical load against air loss, fit an external rod lock or pilot check valve. 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 MFC20X75SCA FAQ
This 20 mm bore cylinder features a 1/8" port and an 8 mm rod. 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, the variable air cushion only decelerates the piston near the stroke end and is not a brake. The piston will drift on air loss, so you need an external rod lock or pilot check valve to hold a suspended load. The -S magnet allows CMSG, DMSG or EMSG sensors for position feedback.
