Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X175U
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X175U is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 175mm 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 MFC40X175U
Delivering 628.3 N of push force at 0.5 MPa, the AirTAC MFC40X175U is a robust JIS-standard round-body mini cylinder built for demanding actuation. It features a SUS304 stainless steel barrel with riveted aluminium covers, resisting mild corrosion and washdown environments. A flat U rear cover provides a flush mounting interface for this 175 mm stroke unit. The 1/4" port feeds the 16 mm piston rod, and the body is notably shorter than an ISO 6432 cylinder of the same bore and stroke.
A defining trait of the MFC series is the variable air cushion at both ends, letting you dial in a needle valve to absorb end-of-stroke shock at high speeds rather than relying on a fixed bumper. This protects machinery and reduces noise during rapid cycling. For practical sizing, the 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. Note that this specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG position switches.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X175U Is Used
High-Speed Package Diverting
Uses the 628.3 N push force to deflect heavy cartons on a sorter line, with the needle-adjustable air cushion preventing harsh slamming at the 175 mm stroke end.
Vertical Load Lowering
Safely lowers a 30 kg fixture by leveraging the variable cushion to ease the descent, though an external pilot check valve is required to hold the load securely on air loss.
Washdown Gate Actuation
Operates a heavy access door in a humid processing area, relying on the SUS304 stainless barrel and riveted aluminium covers to resist mild corrosion.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X175U the Right Cylinder?
When sizing this 40 mm bore unit, verify if the force matches your load: if 628.3 N at 0.5 MPa is excessive, step down to the MFC32 which provides 402.2 N. Since 40 mm is the largest available bore in this series, moving up in force class requires an external rod lock or a different cylinder family entirely. The adjustable air cushion is essential if you are driving heavy loads at high velocities, as it decelerates the piston smoothly to prevent impact damage.
Keep in mind that the air cushion only slows the piston near the end of its travel; it does not function as a brake or lock. If your application must hold a vertical load when air pressure drops or the valve is centered, the piston will drift, requiring an external pilot-operated check valve or rod lock. Furthermore, without the -S magnet option, this model cannot support magnetic sensing—choose an -S variant if you need CMSG, DMSG, or EMSG switches.
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 MFC40X175U FAQ
This 40 mm bore cylinder features a 1/4" port and a 16 mm 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. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet, meaning it cannot support CMSG, DMSG, or EMSG switches. You would need the -S variant for position sensing. It also features a flat U back cover and a variable air cushion at both ends to decelerate loads, not to hold them.
