Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X80SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X80SU is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø32mm 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 MFC32X80SU
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MFC32X80SU is a JIS-standard round-body mini cylinder built for demanding tasks. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments. For the same 32 mm bore and 80 mm stroke, this riveted body is noticeably shorter than a standard ISO 6432 cylinder, saving valuable mounting length.
A defining trait of the MFC series is the variable air cushion at both ends. By turning a needle, you tune the end-of-stroke deceleration to absorb high-speed shock, protecting the load and cutting noise. The built-in piston magnet (-S) supports CMSG, DMSG, and EMSG switches for position sensing, while the U flat-end rear cover simplifies direct mounting. Derived from its 0.5 MPa push rating, the safe working load is roughly 241 N, lifting about 20.5 kg vertically with a 2:1 margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X80SU Is Used
Package Diverting
Pushes medium-weight cartons at high speed onto secondary lines. The tuned air cushions absorb the 80 mm stroke impact, preventing load damage and reducing clatter.
Component Pressing
Applies up to 241 N of safe working force to seat bearings or pins. The riveted stainless build handles light splashing from machining fluids without corroding.
Vertical Lift Stops
Lifts roughly 20.5 kg of stock vertically. The needle-set deceleration cushions the load at the top of the stroke, preventing harsh bouncing during fast cycles.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X80SU the Right Cylinder?
When sizing this 32 mm bore, check both ends of the range: the smaller MFC25 provides 245.3 N at 0.5 MPa, while the larger MFC40 offers 628.3 N. Choose this MFC32 model when your application sits right in that middle force band and requires smooth stops at high cycling speeds. The 1/4" port and M10x1.25 male rod thread match standard pneumatic layouts.
Remember that the adjustable air cushion only decelerates the piston near the stroke end; it does not function as a lock or brake. If the machine loses air, the piston will drift, so fit an external rod lock or pilot-operated check valve for secure load holding. The -S magnet enables CMSG, DMSG, or EMSG sensors, and the U back cover gives you a flat mounting face.
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 MFC32X80SU FAQ
This double-acting cylinder has a 1/4" port and a 12 mm rod. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, or 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
It features a variable air cushion at both ends; you adjust a needle to decelerate the piston near stroke end, which reduces shock but is not a brake. Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG position switches.
