Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD32X450S
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD32X450S is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 450mm stroke, 1/4" 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 MFCD32X450S
Twin rods exiting both covers define the MFCD32X450S, giving equal 345.6 N force in both directions while steadying the load against rotation. This JIS-standard round-body mini cylinder 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. A needle-set variable air cushion at each end absorbs end-of-stroke shock for high-speed 30-800 mm/s operation.
The 450 mm stroke on this unit exceeds the 300 mm standard limit, making it a non-standard made-to-order part. It carries the -S magnet for CMSG, DMSG or EMSG switches. With a 1/4" port and M10x1.25 male rod threads, it yields a safe working load of about 207 N, or roughly 17.6 kg of vertical lift each way with a 2:1 margin.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD32X450S Is Used
Long-Stroke Transfer
Pushes and pulls a 17 kg workpiece carrier over 450 mm at high speed, relying on the 345.6 N equal both-ways force and twin rods to prevent yaw during transit.
Twin-Tool Machining
Mounts a machining head on the front rod and a sensor or stopper on the rear rod, using the variable air cushion to soften deceleration at cycle end.
Vertical Lowering
Lowers a 200 N fixture smoothly without side-play, where the 32 mm bore's 1/4" port provides ample flow and the double rods resist twist on the way down.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD32X450S the Right Cylinder?
Choose this 32 mm bore when you need more push than the MFCD25 (206.1 N at 0.5 MPa) but less bulk than the MFCD40 (527.8 N at 0.5 MPa). The double-rod layout is perfect for twin-tool setups or guiding heavy loads over the extended 450 mm travel, while the adjustable air cushion prevents harsh slamming at high speeds. Note that this 450 mm stroke is non-standard and made to order.
Remember the cushion only decelerates near the stroke end; it is not a brake. If air pressure drops, the piston will drift, so fit an external rod lock or pilot check valve for load holding. Mount using LB foot, FA flange or TC trunnion brackets (there is no SDB option because a rod exits the back cover). The -S magnet allows CMSG, DMSG and EMSG sensors to track position.
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 MFCD32X450S FAQ
It is a double-acting, double-rod cylinder with equal force both ways: 345.6 N at 0.5 MPa, 483.8 N at 0.7 MPa, and a theoretical max of 70.5 kgf at 1.0 MPa. The air port is 1/4" and the male rod thread is M10x1.25.
No, the variable air cushion only decelerates near the stroke end; it is not a lock or brake, so the piston drifts on air loss. Use an external rod lock for holding. The -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG switches.
