Airtac MF20-25 Stainless Steel Mini Cylinder MF20X10UTC
The AirTAC Airtac MF20-25 Stainless Steel Mini Cylinder MF20X10UTC is a genuine double acting JIS-standard round-body mini air cylinder with a Ø20mm bore and 10mm 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 MF20X10UTC
Delivering 157 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder is built for exceptionally tight fixtures. Its SUS304 stainless-steel barrel and riveted rolling-packed aluminium covers resist mild corrosion and washdown, while the 10 mm stroke and 1/8" port keep the footprint minimal. For the same bore and stroke, the MF body is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length. The piston relies on a heterogeneous two-way seal that retains an oil film for long service life, and fixed TPU bumper pads absorb the end-of-stroke impact.
Because the 157 N rating is a theoretical maximum, plan for about 94 N of actual work at 0.5 MPa to account for friction and flow losses. In vertical lifting tasks, this translates to safely raising an 8 kg part with a 2:1 safety margin. The front cover integrates a fixed anti-impact pad alongside the bumpers to decelerate the stroke end, though these do not function as an adjustable air cushion. Note that this specific SKU lacks the internal magnet required for position sensing.

Where the Airtac MF20-25 Stainless Steel Mini Cylinder MF20X10UTC Is Used
Micro-Clamp Actuation
Provides 94 N of safe working force to secure small electronic PCBs inside an automated soldering station.
Short-Stroke Diverter
Uses the 10 mm stroke and TC trunnion mount to push lightweight parcels on a packaging line within a tight 1/8" port envelope.
Part Ejection
Ejects small moulded plastic components from a tooling die, utilising the compact JIS body to fit alongside existing machinery.
Is the Airtac MF20-25 Stainless Steel Mini Cylinder MF20X10UTC the Right Cylinder?
When sizing this 20 mm bore actuator, consider the next size up: the MF25 generates 245.3 N of push force at 0.5 MPa if your fixture demands more thrust. There is no smaller bore in the MF range, making this the most compact option for light-duty clamping. This model includes a U flat-end back cover and is paired with a TC trunnion mount, which accommodates minor misalignment on pivoting axes. Keep in mind that a plain cylinder drifts when air is lost or the valve is centred; the TPU bumpers only soften the stroke end and do not act as a brake. To hold a load securely, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit. Furthermore, because this SKU has no internal magnet, it cannot accept CMSG, DMSG, or EMSG switches—you must specify an -S variant for position feedback.
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 MF20X10UTC 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, this specific SKU does not have an internal magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. It features a SUS304 stainless build shorter than ISO 6432, a U flat-end back cover, and fixed TPU bumper pads rather than an adjustable cushion.
