Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X150S
The AirTAC Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X150S is a genuine double acting, double rod + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 150mm 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 MFCD40X150S
Delivering equal 527.8 N force in both directions at 0.5 MPa, the AirTAC MFCD40X150S is a JIS-standard round-body mini cylinder built for high-speed anti-rotation tasks. A rod exits both aluminium covers, steadying the load and cutting side-play, while the SUS304 stainless barrel resists mild corrosion and washdown. For the same 40 mm bore and 150 mm stroke, this riveted body is notably shorter than an ISO 6432 cylinder, saving valuable mounting length without conforming to that standard.
Needle-set variable air cushions at both ends soak up end-of-stroke shock across the 30-800 mm/s speed range. Because the -S suffix provides a built-in piston magnet, you can directly mount CMSG, DMSG or EMSG sensors for position detection. The 1/4" port and M14x1.5 male rod threads handle robust flow, yielding a safe working load of about 317 N, or roughly 26.9 kg of vertical lift each way with a 2:1 margin.

Where the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X150S Is Used
Twin-Tool Machining Clamp
Uses the 527.8 N bidirectional force to grip parts securely from both sides, while the twin rods keep the clamping face perfectly aligned under high cycle speeds.
High-Speed Divert Gate
Leverages the variable air cushion to slam the divert gate smoothly at the end of travel, preventing impact damage while sorting loads up to 26.9 kg.
Vertical Lift Stopper
Employs the second rod as a back-side stopper or sensor mount, maintaining rigid anti-rotation control as it raises and lowers heavy pallets.
Is the Airtac MFCD Double Rod Cushioned Mini Cylinder MFCD40X150S the Right Cylinder?
When sizing this double-acting family, compare both bores with real figures: the 40 mm option hits 527.8 N at 0.5 MPa, whereas the smaller MFCD32 delivers 345.6 N. Choose the 40 mm bore when moving heavier jigs or absorbing high-speed shocks, as the twin rods prevent twist and the adjustable cushions decelerate smoothly. Remember that the cushion only reduces shock near stroke end—it is not a brake; if you need to hold a vertical load on air loss, add an external rod lock or pilot check valve.
Mounting options include LB foot, FA flange and TC trunnion brackets, with no SDB or back-cover code available because a rod exits both ends. This MFCD40X150S variant includes the -S magnet for electronic or reed switches, whereas a plain SKU without S cannot take a sensor.
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 MFCD40X150S FAQ
The 1/4" ported 40 mm bore generates 527.8 N at 0.5 MPa and 738.9 N at 0.7 MPa. Because it is a double-rod cylinder, this force is identical in both directions, with a theoretical max of 107.6 kgf at 1.0 MPa.
The -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG sensors. The variable air cushion only decelerates the piston near stroke end and does not act as a lock; you must use an external rod lock or pilot check valve to hold a load on air loss.
