Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X160U
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X160U is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 160mm 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 MFC Cushioned Stainless Steel Mini Cylinder MFC40X160U
Delivering 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore mini cylinder handles demanding actuation with precision. The MFC40X160U features a variable air cushion at both ends, allowing you to tune a needle valve to absorb end-of-stroke shock at high cycling speeds, protecting the payload and reducing noise. Its SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments.
Built to JIS standards, the riveted round-body design is notably shorter than an ISO 6432 cylinder for the same bore and stroke, saving valuable mounting length. Equipped with a flat U back cover, this specific SKU lacks a piston magnet and therefore cannot accept CMSG, DMSG, or EMSG sensors. For sizing context, its 628.3 N push force translates to a safe working load of roughly 377 N, or lifting about 32 kg vertically with a 2:1 safety margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X160U Is Used
High-Speed Carton Diversion
Leveraging the 628.3 N push force, this cylinder swiftly redirects heavy packaging on a conveyor belt, while the adjustable air cushion prevents harsh slamming during rapid 160 mm strokes.
Automated Press Ejection
Ejects dense metal or composite parts from a press bed, using the tuned end-cushions to decelerate the 40 mm piston smoothly and protect the machined surface from impact shock.
Vertical Load Lowering
Handles downward pressing tasks where the 527.8 N pull force manages the return stroke, ensuring the flat U cover mounts flush to the machine frame while the cushion softens the descent.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X160U the Right Cylinder?
When sizing this 40 mm bore unit, step down to the MFC32 if your application only requires 402.2 N of push force at 0.5 MPa, as no larger MFC bore exists for heavier loads. The variable air cushion is essential when driving high-speed strokes or moving heavy masses, as it decelerates the piston near the end caps to prevent impact damage. Keep in mind the cushion only slows the stroke; it does not function as a brake.
Because this specific configuration uses a flat U back cover and lacks the -S magnet option, it cannot host position sensors. If your workflow requires intermediate or end-stop detection, you must select an -S variant. Furthermore, since a standard cylinder drifts when air pressure drops or a valve is centred, you must integrate an external rod lock or pilot-operated check valve to suspend a vertical load safely.
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 MFC Cushioned Stainless Steel Mini Cylinder MFC40X160U FAQ
This 40 mm bore cylinder features a 1/4" port and a 16 mm piston rod. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, increasing to 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum force of 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include a piston magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing capabilities. The SUS304 stainless build and variable air cushion still provide excellent washdown resistance and shock absorption.
