Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X15SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X15SCM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 15mm 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 MFC20X15SCM
Designed for high-speed actuation in tight spaces, this JIS-standard round-body mini cylinder uses a SUS304 stainless barrel and riveted aluminium covers to resist mild corrosion and washdown. The MFC20X15SCM features a 20mm bore and 15mm stroke, generating 157N of push force at 0.5MPa. Because the body is shorter than an ISO 6432 cylinder for the same bore and stroke, it saves valuable mounting length without sacrificing power.
A defining trait of the MFC series is the variable air cushion at both ends, which uses a needle valve to soak up end-of-stroke shock, protecting the load and cutting noise better than a fixed bumper. The -S suffix adds a built-in piston magnet for CMSG, DMSG or EMSG switches, while the CM round-end back cover supports specific rear-mounting orientations. For a safe working load, expect around 94N, or roughly 8kg of vertical lift with a 2:1 margin. Air connects via a 1/8" port.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X15SCM Is Used
Pick-and-Place Ejection
Uses the 15mm stroke to rapidly eject small parts, relying on the variable air cushion to prevent end-of-stroke impact at high cycling speeds.
Film Sealing Press
Applies a safe 94N working load to seal packaging film, where the shorter JIS body saves critical machine space over ISO 6432 equivalents.
Small Component Sorting
Lifts lightweight plastic components vertically, using the -S magnet and DMSG switches to confirm positioning in washdown-resistant SUS304 housing.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X15SCM the Right Cylinder?
If 157N of push at 0.5MPa is insufficient for your assembly, step up to the MFC25, which provides 245.3N at the same pressure; there is no smaller bore in the MFC family. The variable air cushion is essential when cycling at high speeds or moving sensitive loads, as it decelerates the piston near the stroke end to reduce impact. Remember that the cushion only slows the piston and does not lock the rod; if you need to hold a load vertically during air loss, install an external rod lock or pilot-operated check valve. This CM back-cover model with the -S magnet pairs perfectly with CMSG, DMSG or EMSG sensors for position feedback.
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 MFC20X15SCM FAQ
This 20mm bore cylinder features a 1/8" port and an 8mm rod with an M8x1.25 male thread. It delivers 157N push and 131.9N pull at 0.5MPa, 219.8N push and 184.7N pull at 0.7MPa, with a theoretical maximum of 32kgf at 1.0MPa.
Yes, the -S suffix indicates a built-in piston magnet for CMSG, DMSG or EMSG switches. However, the variable air cushion only decelerates the piston near stroke end and does not act as a brake; you must use an external rod lock or pilot check valve to hold a load on air loss.
