Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X25CA
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X25CA is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 25mm 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 MFC20X25CA
Taming end-of-stroke shock in tight spaces, the AirTAC MFC20X25CA relies on a needle-adjustable variable air cushion at both ends to decelerate high-speed payloads smoothly. This JIS-standard round-body mini cylinder pushes with 157 N and pulls with 131.9 N at 0.5 MPa. Built with a SUS304 stainless barrel and riveted aluminium covers, it naturally resists mild corrosion and washdown environments.
For the same 20 mm bore and 25 mm stroke, this riveted construction is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length. It provides a safe working load of about 94 N, or roughly 8 kg of vertical lift with a 2:1 margin. This specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG position switches.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X25CA Is Used
Small Part Ejection
Uses the 157 N push force to snap tiny molded components out of a die, relying on the adjustable air cushion to prevent bounce-back at high cycle rates.
Carton Flap Folding
Pivots via the CA rear mount to tuck packaging flaps rapidly, with the needle-set cushion absorbing the impact to protect delicate cardboard.
Light Clamping
Secures lightweight plastic housings for machining, using the 8 mm rod and M8x1.25 thread to hold parts firmly without crushing them.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC20X25CA the Right Cylinder?
When sizing this 20 mm bore unit against the broader MFC family, step down if your payload is extremely light, or move up to the MFC25 which delivers 245.3 N of push force at 0.5 MPa if you need more muscle. The variable air cushion here is essential if you are cycling near the 800 mm/s upper speed limit or moving a sensitive mass, allowing you to dial in the exact deceleration profile.
This CA back cover variant provides a rear pivot point for angular alignment. Remember that the air cushion only decelerates the piston near the stroke end; it does not function as a lock or brake. If your application must hold a load vertically during air loss, add an external rod lock or pilot-operated check valve. Furthermore, because this base model has no magnet, you cannot mount reed or solid-state sensors to it.
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 MFC20X25CA FAQ
This 20 mm bore cylinder features a 1/8" air 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 a magnet. You must purchase the -S variant to use CMSG, DMSG, or EMSG switches. Additionally, the SUS304 stainless build resists mild corrosion, and the variable air cushion only decelerates the load; it is not a brake.
