Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X85SCA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X85SCA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 85mm 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 MFC20X85SCA
Delivering 157 N of push force at 0.5 MPa, this double-acting 20 mm bore mini cylinder is built for fast, shock-sensitive tasks. The MFC20X85SCA features a variable air cushion at both ends, letting you dial in a needle valve to absorb end-of-stroke impact at high speeds, protecting your payload and cutting workshop noise. Its JIS-standard round-body construction uses a SUS304 stainless barrel with riveted aluminium covers to resist mild corrosion and washdown environments.
For the same bore and stroke, this riveted stainless body is notably shorter than an ISO 6432 cylinder, saving valuable mounting length. Equipped with a built-in piston magnet (-S), it supports CMSG, DMSG, and EMSG position switches. The rear CA pivot cover simplifies direct articulating mounts, while the 1/8" port and M8x1.25 male rod thread ensure straightforward integration. Based on the 0.5 MPa push rating, it handles a safe working load of roughly 94 N, lifting about 8 kg vertically with a 2:1 safety margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X85SCA Is Used
Light-Duty Pick & Place
Ideal for transferring small electronic components at high cycle rates, using the adjustable air cushion to prevent harsh impacts when shifting loads at speed.
Blister Pack Sorting
Provides a compact 85 mm stroke for indexing lightweight packaging films, while the SUS304 barrel withstands routine washdowns in food-adjacent lines.
Small Part Diverting
Mounts easily via the CA pivot to swing lightweight gates on a conveyor, relying on the 157 N push force to positively redirect small plastic parts.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X85SCA the Right Cylinder?
When sizing this 85 mm stroke unit, step down if speeds are low and loads are tiny, or step up to the MFC25 (245.3 N push at 0.5 MPa) if you need to move heavier jigs. The 20 mm bore delivers 131.9 N pull at 0.5 MPa, making it ideal for compact pick-and-place arms. Engage the variable air cushion primarily when operating near the 800 mm/s upper speed limit or driving a heavy load that would otherwise slam into the end cap.
Remember that the cushion needle only decelerates the piston near the stroke end; it does not function as a brake or lock. If your application must hold a vertical load during air loss or valve centering, the piston will drift, so you must add an external rod lock or pilot-operated check valve. The -S magnet allows seamless sensor mounting, and you can pair the CA back cover with LB foot, FA flange, or TC trunnion brackets for versatile machine framing.
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 MFC20X85SCA FAQ
This 20 mm bore cylinder has a 1/8" port and an M8x1.25 male rod thread. At 0.5 MPa it provides 157 N push and 131.9 N pull. At 0.7 MPa it provides 219.8 N push and 184.7 N pull. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, the variable air cushion only decelerates the piston near the end of the stroke and acts purely as a shock absorber, not a brake. If air pressure is lost, the piston will drift. For vertical load holding, you must install an external rod lock or a pilot-operated check valve.
