Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X15CM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X15CM 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 MFC20X15CM
Delivering 157 N of push force at 0.5 MPa, the AirTAC MFC20X15CM is a JIS-standard round-body mini cylinder built for high-speed actuation in tight spaces. A variable air cushion at both ends lets you dial in the needle valve to absorb end-of-stroke shock, protecting your payload far better than a fixed rubber bumper. The SUS304 stainless barrel and riveted aluminium covers shrug off mild corrosion and washdown environments.
For the same bore and stroke, this riveted stainless body is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length. Driven by a 1/8" port and an 8 mm rod, it yields a safe working load of roughly 94 N, lifting about 8 kg vertically with a 2:1 safety margin. Note this specific SKU lacks a magnet, so it cannot host CMSG, DMSG, or EMSG sensors.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X15CM Is Used
Micro-Clamp Actuation
Uses the 157 N push force to secure small electronic components during soldering, with the tuned air cushion preventing fragile parts from cracking at rapid cycle speeds.
Short-Stroke Diverting
Pivots lightweight guide rails in packaging lines over a 15 mm travel, where the compact JIS body length saves critical machine footprint compared to standard ISO cylinders.
Parts Ejection
Kicks small plastic mouldings out of a die cavity quickly, relying on the SUS304 stainless barrel to withstand occasional coolant spray and washdown.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X15CM the Right Cylinder?
When sizing this 20 mm bore, step down if your payload is extremely light, or move up to the MFC25, which provides 245.3 N of push force at 0.5 MPa if you need more muscle. The adjustable air cushion is essential here: because the 15 mm stroke is so brief, tuning the needle prevents harsh slamming at high operating speeds. Keep in mind the cushion only decelerates the piston near the end of travel; it does not function as a brake. If your application must hold a load vertically during an air loss event, install an external rod lock or pilot check valve.
Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets, alongside the standard CM round-end back cover. Since this base configuration has no internal magnet, position sensing is impossible on this unit—order the -S variant if you require CMSG, DMSG, or EMSG switches.
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 MFC20X15CM 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, increasing to 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, this specific SKU does not include an internal magnet, meaning it cannot support CMSG, DMSG, or EMSG position switches. You would need to order the -S variant for sensing capabilities. The unit retains its variable air cushion and SUS304 stainless construction regardless.
