Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X135SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X135SU is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 135mm 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 MFC32X135SU
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder is built for demanding mid-weight tasks. The MFC32X135SU features a SUS304 stainless barrel with riveted aluminium covers, resisting mild corrosion and washdown environments. For the same bore and stroke, this riveted construction is notably shorter than an ISO 6432 cylinder, saving valuable mounting length.
A variable air cushion at both ends lets you turn a needle to soak up high-speed end-of-stroke shock, protecting the load and cutting noise versus a fixed bumper. The 135 mm stroke operates at 30-800 mm/s, and the 1/4" port feeds a 12 mm rod with an M10x1.25 male thread. Because the SKU includes the -S suffix, a built-in piston magnet enables CMSG, DMSG, or EMSG position switches. The U flat-end back cover provides a flush rear mounting face. Based on the 0.5 MPa push rating, expect a safe working load around 241 N, or roughly 20.5 kg of vertical lift with a 2:1 margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X135SU Is Used
Package Diverting
Pushes medium-weight cartons at high cycle rates. The variable air cushion absorbs the end-of-stroke impact, preventing damage to the 241 N safe working load.
Light Pressing
Applies 402.2 N of push force at 0.5 MPa to seat small bearings. The 1/4" port ensures adequate flow to maintain speed throughout the 135 mm stroke.
Vertical Lift Stops
Raises components up to 20.5 kg against gravity with a 2:1 safety margin. The U flat-end back cover mounts flush to machine frames for rigid support.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X135SU the Right Cylinder?
When sizing this 32 mm bore, compare it directly with adjacent options: step down to the MFC25 for 245.3 N @0.5 MPa if your load is lighter, or step up to the MFC40 for 628.3 N @0.5 MPa for heavier dynamics. The adjustable air cushion is essential when cycling at high speeds or moving substantial mass, allowing you to fine-tune the deceleration profile. Keep in mind the cushion only decelerates near the stroke end—it is not a lock or brake.
If air pressure drops or the valve is centered, the piston will drift because a plain cylinder does not hold its load; for suspended loads, install an external rod lock or a pilot-operated check valve. This U flat-end model accepts LB foot, FA flange, SDB pivot, and TC trunnion mounts, and the -S magnet ensures compatibility with CMSG, DMSG, and EMSG sensors.
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 MFC32X135SU FAQ
This 32 mm bore cylinder has a 1/4" air port and a 12 mm rod with an M10x1.25 male thread. 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 stroke end; it does not act as a brake or lock, so the piston will drift on air loss. For suspended loads, use an external rod lock or pilot check valve. The -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG position sensors.
