Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X500SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X500SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 500mm 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 MFC20X500SCA
Soaking up high-speed shock with a needle-set variable air cushion at both ends, this double-acting JIS-standard round-body mini cylinder is built for a 20 mm bore and 500 mm stroke. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the built-in magnet (-S) supports CMSG, DMSG and EMSG sensors. A CA pivot back cover handles rear mounting.
At 0.5 MPa it pushes 157 N and pulls 131.9 N, translating to a safe working load of roughly 94 N or a 2:1 vertical lift of about 8 kg. Fed by a 1/8" port with an 8 mm rod, it runs 30-800 mm/s. For the same bore and stroke, the MFC body is shorter than an ISO 6432 cylinder, saving valuable machine space.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X500SCA Is Used
Long-Stroke Diverting
Pushes light packages across a conveyor over the full 500 mm travel, relying on the variable air cushion to prevent end-of-stroke slamming at high speed.
Vertical Lowering
Lowers an 8 kg fixture smoothly using the 2:1 safety margin, where the adjustable cushion absorbs the downward kinetic energy just before the bottom.
Film Feed Roll
Actuates a packaging feed mechanism, using the SUS304 stainless construction to withstand routine washdowns in food or beverage environments.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X500SCA the Right Cylinder?
If 157 N of push at 0.5 MPa is insufficient, step up to the MFC25 which provides 245.3 N; there is no smaller bore in the MFC family. The variable air cushion is essential when moving loads at high speed over the 500 mm travel, as it decelerates the piston smoothly. Note that the cushion only softens end-of-stroke impact and does not lock the rod; if you need to hold a load vertically during air loss, add an external rod lock or pilot check valve.
The -S magnet enables CMSG, DMSG or EMSG switches for position sensing. Mounting options include LB foot, FA flange, SDB pivot and TC trunnion, with this specific CA back cover providing a rear pivot point.
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 MFC20X500SCA FAQ
This 20 mm bore cylinder uses a 1/8" port. It pushes 157 N and pulls 131.9 N at 0.5 MPa, pushes 219.8 N and pulls 184.7 N at 0.7 MPa, and has a theoretical maximum force of 32 kgf at 1.0 MPa.
No, the variable air cushion only decelerates the piston near the stroke end to reduce shock; it is not a brake or lock. The piston will drift on air loss, so use an external rod lock or pilot check valve for holding. The -S magnet allows CMSG, DMSG and EMSG sensors to track position.
