Airtac MF20-25 Stainless Steel Mini Cylinder MF20X125SCA
The AirTAC Airtac MF20-25 Stainless Steel Mini Cylinder MF20X125SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø20mm bore and 125mm 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 MF20X125SCA
Generating 157 N of push force at 0.5 MPa, this double-acting stainless steel mini cylinder packs reliable actuation into a compact JIS-standard round body. The SUS304 barrel and riveted aluminium covers resist mild corrosion and washdown, while the piston's two-way seal retains an oil film for long service life. Because the MF body is shorter than an ISO 6432 cylinder for the same 20 mm bore and 125 mm stroke, it saves valuable mounting length in tight fixtures.
This specific SKU includes a built-in piston magnet for position sensing and features a CA rear pivot cover. The fixed TPU bumper pads soften stroke-end impact without offering adjustable cushioning. For practical sizing, plan for about 94 N of real work at 0.5 MPa, which means it can safely lift an 8 kg part vertically with a 2:1 safety margin.

Where the Airtac MF20-25 Stainless Steel Mini Cylinder MF20X125SCA Is Used
PCB Depaneling Gate
Cycles a lightweight routing blade to singulate circuit boards, using the 125 mm stroke to clear the fixture during tool changes.
Bin Divert Arm
Pushes small plastic totes onto a secondary conveyor lane, relying on the SUS304 body to withstand occasional washdown.
Part Ejector
Kicks finished moulded components out of a press area, safely handling the 8 kg vertical lift capacity at 0.5 MPa.
Is the Airtac MF20-25 Stainless Steel Mini Cylinder MF20X125SCA the Right Cylinder?
When sizing this 20 mm bore actuator, evaluate your force needs carefully. If 157 N of push at 0.5 MPa is insufficient, stepping up to the MF25 provides 245.3 N; since 20 mm is the smallest available MF bore, there is no smaller option for lighter duties. The 1/8" port and M8x1.25 male rod thread are fixed by the bore size.
The -S magnet allows CMSG, DMSG, or EMSG switches to track piston position. With the 125 mm stroke, minimize side loads to prevent rod bending. Note that a standard cylinder drifts when air is lost or the valve is centred; the bumpers only decelerate the stroke end and do not act as a brake. Use an external rod lock or pilot check valve for held loads.
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 MF20X125SCA 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 of 32 kgf at 1.0 MPa.
No, the MF is a JIS-standard round-body cylinder that is physically shorter than an ISO 6432 unit, so it will not match ISO footprint hardware. It uses fixed TPU bumper pads for impact deceleration, not an adjustable air cushion. The CA back cover provides a pivot mount.
