Airtac MF20-25 Stainless Steel Mini Cylinder MF20X10CMLB
The AirTAC Airtac MF20-25 Stainless Steel Mini Cylinder MF20X10CMLB 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 MF20X10CMLB
Generating 157 N of push force at 0.5 MPa, this double-acting 20 mm bore mini cylinder is built for tight fixtures where every millimetre counts. Because the JIS-standard round body is physically shorter than a comparable ISO 6432 unit for the same 10 mm stroke, it packages neatly into compact machinery. The SUS304 stainless barrel and riveted aluminium covers shrug off mild washdown, while the internal two-way seal retains an oil film for long service life.
Driven by a 1/8 inch port and an 8 mm rod with an M8x1.25 thread, it moves at 30-800 mm/s. Fixed TPU bumper pads and a front-cover anti-impact pad absorb the stroke-end shock. For practical sizing, plan for about 94 N of real work at 0.5 MPa, which means it can safely lift an 8 kg vertical load with a 2:1 safety margin.

Where the Airtac MF20-25 Stainless Steel Mini Cylinder MF20X10CMLB Is Used
Gripper Actuation
Drives small pneumatic grippers in electronics assembly, using the 10 mm stroke to open and close jaws on delicate components with precise 157 N force.
Carton Flap Folding
Folds lightweight cardboard flaps on compact packaging lines, where the short JIS body saves valuable mounting length along the conveyor.
Part Ejection
Ejects small moulded plastic parts from tight tooling cavities, relying on the SUS304 stainless barrel to withstand occasional coolant spray.
Is the Airtac MF20-25 Stainless Steel Mini Cylinder MF20X10CMLB the Right Cylinder?
If your task requires less push, stepping down is not an option as 20 mm is the smallest available MF bore. If you need more force, the MF25 bore provides 245.3 N at 0.5 MPa. This specific SKU includes a CM round-end rear cover and an LB foot mounting bracket for stable base fixation.
Because this configuration lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG position switches; you must physically verify stroke completion or select an -S variant. Remember that a standard cylinder drifts if air pressure drops or the valve is centred—the bumpers only decelerate the stroke end, so install an external pilot check valve if you need to arrest a falling load.
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 MF20X10CMLB FAQ
This 20 mm bore cylinder features a 1/8 inch port and an M8x1.25 male rod thread. At 0.5 MPa it pushes with 157 N and pulls with 131.9 N. At 0.7 MPa the push is 219.8 N and pull is 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG or EMSG switches. It mounts via an LB foot bracket and features a CM round-end rear cover. The fixed TPU bumpers decelerate the piston at the stroke end but do not function as an adjustable air cushion.
