Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X325SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X325SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 325mm 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 MFC20X325SCA
Tame high-speed end-of-stroke shock with the AirTAC MFC20X325SCA, a JIS-standard round-body mini cylinder built with a SUS304 stainless barrel and riveted aluminium covers. The integrated variable air cushion at both ends lets you dial in the deceleration needle to protect payloads, a major upgrade over fixed rubber bumpers. Delivering 157 N of push force at 0.5 MPa, it yields a safe working load of roughly 94 N and lifts about 8 kg vertically with a 2:1 margin.
For the same 20 mm bore and 325 mm stroke, this riveted construction is notably shorter than an ISO 6432 cylinder, saving valuable machine space without sacrificing the 325 mm travel. The -S suffix adds a piston magnet for CMSG, DMSG or EMSG switches, while the CA rear pivot cover simplifies angular mounting. Fluid ports are 1/8".

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X325SCA Is Used
Light-Part Ejection
Uses the 157 N push stroke to eject small plastic parts from a mould at high speed, relying on the tuned air cushion to prevent end-of-stroke banging.
Package Diverting
Swings a diverter arm along the 325 mm stroke to sort light boxes on a belt line, with the CA pivot absorbing side loads during transit.
Vertical Tray Lifting
Raises stacked trays weighing up to 8 kg using the 0.5 MPa thrust, using the needle cushion to soften the stop at the top of the 325 mm travel.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X325SCA the Right Cylinder?
If 157 N push at 0.5 MPa is too light, step up to the MFC25X325SCA which provides 245.3 N; since 20 mm is the smallest MFC bore, there is no smaller option. The adjustable cushion is essential when cycling at high speeds (up to 800 mm/s) with heavy loads, as it prevents harsh impacts. Remember the cushion only decelerates near the stroke end—it is not a brake. If you need to hold a vertical load during air loss, add an external rod lock or pilot check valve. The CA back cover suits pivot mounts, and the -S magnet enables position sensing.
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 MFC20X325SCA FAQ
This 20 mm bore cylinder has a 1/8" port and an 8 mm rod. It generates 157 N push and 131.9 N pull at 0.5 MPa, or 219.8 N push and 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, the piston will drift if air is lost. The variable air cushion at both ends only decelerates the piston near the stroke end to reduce shock; it does not act as a lock or brake. Use an external rod lock or pilot check valve for load holding.
