Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X30CA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X30CA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 30mm 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 MFC20X30CA
Dial in end-of-stroke deceleration with the AirTAC MFC20X30CA, a JIS-standard round-body mini cylinder built for double-acting operation. A needle-set variable air cushion at both ends absorbs high-speed 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, and for the same 20 mm bore and 30 mm stroke, this body is noticeably shorter than an ISO 6432 cylinder.
Generating 157 N of push and 131.9 N of pull at 0.5 MPa, this 1/8" ported unit fits tight spaces. It yields a safe working load of roughly 94 N, meaning it lifts about 8 kg vertically with a 2:1 safety margin. The CA rear pivot cover simplifies angular mounting, though note this specific SKU lacks a magnet and cannot host CMSG, DMSG or EMSG sensors.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X30CA Is Used
Light Part Ejection
Cushions the rapid ejection of small plastic parts from a mould at high cycle rates, using the 157 N push force to clear the tool without slamming the end cap.
Package Diverting
Handles short 30 mm diverting strokes on a packaging line, where the adjustable air cushion silently stops the rod to prevent jolting lightweight cardboard boxes.
Small Component Pressing
Presses delicate electronic connectors into place with a safe working load of 94 N, decelerating smoothly at the stroke end to avoid crushing the component.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X30CA the Right Cylinder?
When sizing this 20 mm bore, step up to the MFC25 if you need more force, as it provides 245.3 N of push at 0.5 MPa; since 20 mm is the smallest available MFC bore, there is no smaller option. The variable air cushion is essential if you are driving heavy loads or running near the 800 mm/s maximum speed, letting you tune the deceleration to prevent end-cap banging.
Remember that the cushion only slows the piston near the stroke end and acts purely as a shock absorber, never as a lock or brake. If your application must hold position on air loss, install an external rod lock or pilot check valve. For position feedback, you must select the -S magnet variant, as this base SKU cannot accept a switch.
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 MFC20X30CA 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, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum of 32 kgf at 1.0 MPa.
This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG switches; you need the -S variant for sensing. The CA back cover provides a rear pivot point for clevis mounting, and the SUS304 stainless build resists mild corrosion.
