Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X75SCM
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X75SCM is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø40mm bore and 75mm 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 MFC40X75SCM
Delivering 628.3 N of push force at 0.5 MPa, this double-acting 40 mm bore mini cylinder handles heavy loads with precision. The defining feature of the MFC series is the variable air cushion at both ends; by turning a needle valve you tune the deceleration to absorb high-speed shock, protecting the machinery and reducing noise far better than a fixed bumper. The riveted SUS304 stainless steel barrel and aluminium covers resist mild corrosion and washdown environments.
Thanks to its JIS-standard round-body design, the overall envelope is shorter than an ISO 6432 cylinder for the same 75 mm stroke, saving valuable mounting length. This specific MFC40X75SCM variant includes a built-in piston magnet for position sensing and uses a CM round-end rear cover. Operating at speeds from 30 to 800 mm/s, it provides a safe working load of roughly 377 N, meaning it can lift about 32 kg vertically with a 2:1 safety margin. The fluid port is 1/4".

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X75SCM Is Used
Heavy Carton Diversion
Pushes heavy packaged goods at high speed across sorting lines; the adjustable air cushion absorbs the 628.3 N impact at stroke end to prevent load damage.
Clamping in CNC Fixtures
Provides robust 0.5 MPa clamping for metal parts; the SUS304 body handles coolant splashes while the CM rear cover allows flexible pivot mounting.
Vertical Pallet Stops
Acts as a high-speed stop for pallets; lifts about 32 kg vertically and uses the needle-set cushion to silently decelerate the shifting load.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC40X75SCM the Right Cylinder?
When sizing this 40 mm bore, 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 loads exceeding the 628.3 N provided here. The variable air cushion is essential if you are moving heavy payloads at high speeds, allowing you to dial in the exact end-of-stroke deceleration. Remember that the cushion only decelerates the piston; it does not act as a brake. Because a standard cylinder will drift and lose its position on air loss or when a valve is centered, you must add an external rod lock or pilot-operated check valve for secure load holding.
This SKU includes the -S magnet, enabling direct mounting of CMSG, DMSG, or EMSG reed and electronic switches for end-position feedback. It features an M14x1.5 male rod thread and a CM round-end back cover. You can mount it using LB foot brackets, FA flanges, SDB pivot blocks, or TC trunnions depending on your spatial constraints.
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 MFC40X75SCM FAQ
This 40 mm bore cylinder has a 1/4" port and an M14x1.5 male rod 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 force of 128.1 kgf at 1.0 MPa.
No, the variable air cushion only decelerates the piston near the stroke end and is not a locking brake. The piston will drift on air loss or when a valve is centered. For secure load holding, install an external rod lock or pilot check valve. The -S magnet supports CMSG/DMSG/EMSG sensors.
