Airtac MF20-25 Stainless Steel Mini Cylinder MF20X130CM
The AirTAC Airtac MF20-25 Stainless Steel Mini Cylinder MF20X130CM 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 MF20X130CM
Generating 157 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder is built around an SUS304 stainless-steel barrel with riveted aluminium covers. Because the MF body is physically shorter than an ISO 6432 cylinder for the same 20 mm bore and 130 mm stroke, it fits tighter fixtures and saves valuable mounting length. The CM round-end back cover simplifies rear pivot mounting.
The piston relies on a two-way oil-retaining seal for long life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impact. Note this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG or EMSG position switches. Plan for roughly 94 N of real 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 MF20X130CM Is Used
PCB Depaneling Gate
Pushes a routing gate open on an electronics assembly line, where the 8 kg vertical lift capacity easily handles lightweight aluminium jigs.
Carton Flap Folder
Folds minor corrugated flaps on a packaging conveyor, leveraging the short JIS body to fit between narrow side rails.
Lab Sample Divertor
Actuates a pivot arm to route sample vials into testing carousels, benefiting from the SUS304 barrel's washdown resistance.
Is the Airtac MF20-25 Stainless Steel Mini Cylinder MF20X130CM the Right Cylinder?
When sizing this 20 mm bore, stepping up to the MF25 increases your 0.5 MPa push force to 245.3 N, while no smaller AirTAC MF bore exists below 20 mm. The 1/8" port and M8x1.25 male rod thread are fixed by this bore size. If your fixture requires position feedback, select the -S magnet version instead, as this plain unit cannot host a sensor.
At 130 mm of stroke, mind the rod-bending risk from side loads. Furthermore, a standard MF does not hold its load if air pressure drops or the valve is centred; the piston will drift. For vertical or suspended loads, install an external rod lock or a pilot-operated check valve.
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 MF20X130CM 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.
No, this specific SKU lacks the internal magnet required for switches. You must choose the MF20X130CM-S variant to use CMSG, DMSG or EMSG sensors. The CM back cover provides a round-end for pivot mounting, and fixed TPU bumpers decelerate the stroke end.
