Airtac MF20-25 Stainless Steel Mini Cylinder MF20X100CA
The AirTAC Airtac MF20-25 Stainless Steel Mini Cylinder MF20X100CA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø20mm bore and 100mm 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 MF20X100CA
Delivering 157 N of push force at 0.5 MPa, the AirTAC MF20X100CA is a JIS-standard round-body mini cylinder engineered for tight fixtures. Because its riveted rolling-packed structure is physically shorter than an equivalent ISO 6432 unit for the same 20 mm bore and 100 mm stroke, it saves valuable mounting length without sacrificing the 8 mm rod stroke. The SUS304 stainless barrel and aluminium covers resist mild corrosion and washdown, while the piston's two-way seal retains an oil film for long service life.
This double-acting actuator operates on a 1/8 inch port at speeds from 30 to 800 mm/s. Fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impact by decelerating the piston, though they do not provide adjustable cushioning. Plan for roughly 94 N of actual work at 0.5 MPa, which means it can comfortably lift about 8 kg vertically with a 2:1 safety margin. The rear CA pivot cover allows direct angular mounting.

Where the Airtac MF20-25 Stainless Steel Mini Cylinder MF20X100CA Is Used
Small Part Ejection
Uses the 157 N push force to eject small moulded plastic parts from a fixture, where the compact JIS body fits neatly inside the press frame.
Package Diverting
Employs the 100 mm stroke to push light cardboard cartons onto an adjacent conveyor line, relying on the SUS304 barrel to withstand occasional washdown.
Clamp Actuation
Actuates a secondary pneumatic clamp on an assembly jig, taking advantage of the CA pivot back cover to accommodate slight angular misalignment.
Is the Airtac MF20-25 Stainless Steel Mini Cylinder MF20X100CA the Right Cylinder?
When sizing this 20 mm bore actuator, verify your force requirements against the 131.9 N pull at 0.5 MPa; if your application needs more thrust, stepping up to the MF25 provides 245.3 N at the same pressure. Since 20 mm is the smallest available MF bore, there is no smaller option in this series. This specific SKU lacks the -S magnet, meaning it cannot accept CMSG, DMSG, or EMSG position switches; you must select an -S variant if sensing is required. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion, but this unit ships with a CA pivot back cover. For the 100 mm stroke, ensure the load is guided to prevent rod bending and premature seal wear. Note that a standard cylinder drifts when air is removed or a valve is centred, so install an external rod lock or pilot check valve if the load must be held in place.
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 MF20X100CA FAQ
This 20 mm bore double-acting cylinder has a 1/8 inch 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.
This specific SKU does not have the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. The CA back cover provides a rear pivot point for clevis mounting, and the fixed TPU bumper pads decelerate the stroke end but do not function as an adjustable air cushion.
