Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X145SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X145SU is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 145mm 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 MFC32X145SU
Tuned for high-speed shock absorption, the AirTAC MFC32X145SU relies on a needle-set variable air cushion at both ends to decelerate heavy loads smoothly rather than slamming them into a fixed bumper. This JIS-standard round-body mini cylinder features a SUS304 stainless barrel and riveted aluminium covers, offering mild corrosion and washdown resistance while maintaining a shorter overall length than an ISO 6432 unit for the same 32 mm bore and 145 mm stroke.
Generating 402.2 N of push and 345.6 N of pull at 0.5 MPa, this double-acting actuator is built for substantial work. A practical safe working load sits around 241 N, and it can vertically lift about 20.5 kg with a 2:1 margin. The flat-end U back cover simplifies direct mounting, and because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG or EMSG position switches.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X145SU Is Used
Package Diverting
Pushes heavy cartons at high speed onto secondary lines where the variable air cushion prevents harsh slams that could damage packaging.
Vertical Load Lowering
Lowers approximately 20.5 kg payloads smoothly, using the adjustable needle to decelerate the mass before reaching the flat-end U cover.
Light Pressing Tasks
Applies up to 402.2 N of push at 0.5 MPa for seating small bearings or components, benefiting from the SUS304 barrel in mildly humid shops.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X145SU the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MFC25 drops the 0.5 MPa push force to 245.3 N, while stepping up to the MFC40 raises it to 628.3 N. Choose this model when moving heavier masses at high speeds where the adjustable end-of-stroke cushioning is essential to protect the machinery and reduce noise.
Keep in mind the variable cushion only decelerates the piston near the stroke end; it does not function as a lock or brake. If your application must hold a load vertically during air loss or valve centering, the piston will drift, so you must add an external rod lock or pilot-operated check valve. Alongside the U back cover, you can mount the body using LB foot, FA flange, SDB pivot or TC trunnion brackets, and the air connection is a 1/4 inch port.
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 MFC32X145SU FAQ
This double-acting cylinder has a 1/4 inch port and a 12 mm rod. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum of 82 kgf at 1.0 MPa.
No, the variable air cushion only decelerates the piston near the end of the stroke and is not a brake. If air loss occurs, the piston will drift, so you need an external rod lock or pilot check valve to hold a load. The built-in -S magnet supports CMSG, DMSG and EMSG sensors.
