Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X150S
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X150S is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø20mm bore and 150mm 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 MFCD Double Rod Cushioned Mini Cylinder MFCD20X150S
Needle-set air cushions at both ends define this JIS-standard round-body mini cylinder, absorbing high-speed end-of-stroke shock while twin rods deliver equal force both ways. The AirTAC MFCD20X150S uses a SUS304 stainless barrel with riveted aluminium covers, offering a shorter mounting envelope than an ISO 6432 unit of the same bore and stroke. It provides 131.9 N of thrust at 0.5 MPa and 184.7 N at 0.7 MPa in each direction.
The 20 mm bore hosts an 8 mm rod at each end (M8x1.25 thread) and a 1/8" port. With a safe working load around 79 N, it handles roughly 6.7 kg vertically per direction with a 2:1 margin. The built-in magnet (-S) supports CMSG, DMSG or EMSG sensors. Note that the cushion only decelerates the load; use an external rod lock or pilot check valve to hold position on air loss.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X150S Is Used
Twin-Tool Transfer
Drives a 150 mm transfer stroke for light electronic components, using the second rod to mount a synchronous stopper while the air cushion absorbs high-speed impact.
Anti-Rotation Lift
Raises and lowers a 6 kg machining fixture against side-play, relying on the dual 8 mm rods to prevent twisting during vertical motion at 0.5 MPa.
Cushioned Clamping
Clamps delicate aluminium extrusions with equal push and pull force, where the needle-set cushion quietly decelerates the 131.9 N thrust to prevent workpiece denting.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD20X150S the Right Cylinder?
Choose the MFCD20 when your application needs roughly 79 N of safe working load, as it generates 131.9 N at 0.5 MPa both ways. If your payload is heavier, step up to the MFCD25, which outputs 206.1 N at 0.5 MPa. This 20 mm bore variant with a 150 mm stroke runs at 30-800 mm/s and uses a 1/8" port.
The twin rods prevent rotation and support a second tool, while the variable air cushion soaks up shock at high speeds. Mounting options include LB foot, FA flange, or TC trunnion (no SDB). Because this SKU includes the -S magnet, you can fit CMSG, DMSG or EMSG switches for position sensing.
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 MFCD Double Rod Cushioned Mini Cylinder MFCD20X150S FAQ
The double-acting, double-rod design outputs equal force both ways: 131.9 N at 0.5 MPa, 184.7 N at 0.7 MPa, and a theoretical maximum of 26.9 kgf at 1.0 MPa. It features a 20 mm bore, 8 mm rods, and a 1/8" port.
No, the variable air cushion at both ends only decelerates the piston near the stroke end to reduce shock; it is not a brake. For load holding on air loss, install an external rod lock or pilot check valve. The -S magnet allows CMSG/DMSG/EMSG sensors for position feedback.
