Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X80U
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X80U is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 80mm 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 MFC40X80U
Delivering 628.3 N of push force at 0.5 MPa, the AirTAC MFC40X80U is a robust JIS-standard round-body mini cylinder built for demanding high-speed tasks. It features a SUS304 stainless steel barrel with riveted aluminium covers, resisting mild corrosion and washdown environments. This 40 mm bore, 80 mm stroke double-acting actuator uses a needle-set variable air cushion at both ends to soak up end-of-stroke shock, protecting the load and cutting noise. It also carries a fixed anti-impact pad on the front cover and a flat-end U rear cover.
For the same bore and stroke, this riveted construction is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length without sacrificing power. Operating at speeds of 30-800 mm/s via a 1/4" port, it yields a safe working load of about 377 N (60% of the 0.5 MPa push force) and lifts roughly 32 kg vertically with a 2:1 margin. Note that this specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X80U Is Used
Package Diverting
Handles heavy carton redirection on conveyors using its 628.3 N push force, while the variable air cushion absorbs the impact of sudden stops at high cycle rates.
Pallet Positioning
Lifts and positions loaded pallets up to 32 kg vertically, relying on the flat-end U cover and robust SUS304 barrel for reliable operation in busy logistics hubs.
Press Ejection
Ejects dense machined parts from a press bed, utilizing the needle-set cushion to prevent damage to both the workpiece and the machinery during rapid retraction.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X80U the Right Cylinder?
If 402.2 N from the MFC32 is insufficient for your payload, this 40 mm bore model provides the necessary step up in thrust. Since 40 mm is the largest available bore in the MFC family, moving beyond 879.6 N at 0.7 MPa requires a different cylinder series. The adjustable air cushion is essential when moving heavy loads at high velocities, as it decelerates the piston smoothly near stroke end. Remember that the cushion is not a brake; if air pressure drops, the piston will drift, so fit an external rod lock or pilot check valve for secure load holding. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion to suit your layout.
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 MFC40X80U FAQ
This double-acting cylinder has a 1/4" port and a 16 mm rod with an M14x1.5 male thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum of 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You must order the -S variant to enable sensing. The variable air cushion at both ends functions only to decelerate the piston near stroke end, not to hold the load.
