Airtac MF20-25 Stainless Steel Mini Cylinder MF20X130SCA
The AirTAC Airtac MF20-25 Stainless Steel Mini Cylinder MF20X130SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø20mm bore and 130mm 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 MF20-25 Stainless Steel Mini Cylinder MF20X130SCA
Generating 157 N of push force at 0.5 MPa, this double-acting AirTAC mini cylinder features a 20 mm bore and 130 mm stroke. Its JIS-standard round body is purposefully shorter than a comparable ISO 6432 unit, delivering a tangible packaging win for tight machine fixtures. The SUS304 stainless steel barrel and riveted rolling-packed aluminium covers resist mild corrosion and washdown environments.
Equipped with a built-in piston magnet (-S), it supports CMSG, DMSG, and EMSG sensors for position detection. The piston relies on a heterogeneous two-way seal that retains an oil film for long service life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts. Plan for roughly 94 N of actual work at 0.5 MPa, which translates to lifting about 8 kg vertically with a 2:1 safety margin.

Where the Airtac MF20-25 Stainless Steel Mini Cylinder MF20X130SCA Is Used
Small Part Ejection
Uses the 131.9 N pull force at 0.5 MPa to reliably strip small plastic moulded components from a die plate.
Package Diverting
Actuates a lightweight routing flap on a packaging line, taking advantage of the compact JIS body length.
Pivot Arm Actuation
Leverages the CA rear pivot mount to drive a short 130 mm stroke angular clamping arm in an assembly fixture.
Is the Airtac MF20-25 Stainless Steel Mini Cylinder MF20X130SCA the Right Cylinder?
When sizing this 20 mm bore unit, consider stepping up to the MF25 if your application requires more thrust, as the larger bore provides 245.3 N of push force at 0.5 MPa. Since 20 mm is the smallest available MF bore, dropping down a size is not an option. This specific SKU includes a CA rear pivot cover, making it ideal for clevis mounting, and its integrated magnet is fully compatible with CMSG, DMSG, and EMSG switches.
Remember that a standard double-acting cylinder will drift if air pressure is lost or the directional valve is centred; the bumpers only decelerate the stroke end and do not function as a braking lock. To suspend a load safely, install an external rod lock or a pilot-operated check valve. Additionally, at 130 mm, verify your mounting geometry to prevent excessive side loading on the 8 mm rod.
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 MF20-25 Stainless Steel Mini Cylinder MF20X130SCA FAQ
This 20 mm bore cylinder features a 1/8" port and an M8x1.25 male rod thread. 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 force of 32 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG, or EMSG switches directly onto the SUS304 stainless barrel for precise position detection.
