Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X200U
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X200U is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 200mm 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 MFC40X200U
Delivering 628.3 N of push force at 0.5 MPa, the AirTAC MFC40X200U is a JIS-standard round-body mini cylinder built for heavy-duty actuation. It features a 40 mm bore, a 200 mm stroke, and a U flat-end rear cover. The 1/4" port feeds the double-acting piston, which achieves a theoretical maximum output of 128.1 kgf at 1.0 MPa.
A defining trait of this MFC series is the variable air cushion at both ends: a needle valve lets you dial in deceleration to absorb high-speed shock, protecting the load and reducing noise. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown environments. For the same bore and stroke, this riveted body is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length. With a safe working load of roughly 377 N, it can vertically lift about 32 kg with a 2:1 safety margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X200U Is Used
Package Diversion
Handles robust 32 kg carton diverting on high-speed belts where the variable air cushion absorbs the energetic end-of-stroke shock without slamming.
Press Ejection
Ejects dense stamped parts from a press, using its 628.3 N push force at 0.5 MPa to reliably clear heavy tooling before the next cycle.
Pallet Lift Stops
Acts as a heavy-duty stopper for loaded pallets, relying on the needle-adjustable cushion to decelerate the mass smoothly and prevent mechanical bounce.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X200U the Right Cylinder?
When sizing this 40 mm bore unit, dropping down to the MFC32 provides 402.2 N of push force at 0.5 MPa, which is insufficient if you need the full 628.3 N capability of this model. Since 40 mm is the largest available bore in the MFC family, you cannot step up further within this series for heavier loads. The adjustable cushion is essential when cycling at high speeds or moving heavy masses, as it smooths the end-of-stroke impact. Note that this SKU lacks a magnet and cannot accept CMSG, DMSG, or EMSG sensors; you would need the -S variant for position detection. Furthermore, the air cushion only decelerates the piston near the stroke end and does not function as a lock—if you must prevent drift on air loss, install an external rod lock or pilot check valve. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets.
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 MFC40X200U FAQ
This 40 mm bore cylinder has a 1/4" air 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, and 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 specify the -S variant for sensing. The U flat-end rear cover and SUS304 stainless barrel offer flexible mounting and washdown resistance.
