Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X15SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X15SU is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 15mm 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 MFC32X15SU
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore mini cylinder handles short 15 mm strokes with precision. The variable air cushion at both ends lets you dial in a needle valve to absorb end-of-stroke shock during high-speed cycles, protecting your machinery far better than a fixed bumper. Because the -S suffix denotes a built-in piston magnet, you can mount CMSG, DMSG, or EMSG reed and electronic switches directly for position sensing.
Built with a SUS304 stainless steel barrel and riveted aluminium covers, the JIS-standard round-body construction resists mild corrosion and washdown environments. For the same bore and stroke, this compact riveted body is physically shorter than an ISO 6432 cylinder, conserving valuable machine space. The flat-end U rear cover provides a straightforward flush mounting face. Based on the 0.5 MPa push rating, it handles a safe working load of roughly 241 N, meaning it can vertically lift about 20.5 kg with a 2:1 safety margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X15SU Is Used
Short-Stroke Clamping
Ideal for locking lightweight aluminium extrusions in place, using its 15 mm stroke and 241 N safe working load to secure parts rapidly before machining.
Package Diverting
Deploy the 402.2 N push force to snap a diverter arm into position on a high-speed packaging line, relying on the variable air cushion to prevent end-of-stroke slamming.
Vertical Lift Stops
Lift small tote bins up to 20.5 kg vertically, using the built-in magnet and CMSG switches to confirm the raised position before the conveyor advances.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X15SU the Right Cylinder?
When sizing this 32 mm bore, check both directions: if 402.2 N at 0.5 MPa is excessive, step down to the MFC25 which provides 245.3 N; if you need more muscle, the MFC40 pushes 628.3 N. The adjustable air cushion is essential when moving heavier payloads at high speeds, as it decelerates the piston smoothly right before the end of stroke. Note that this cushion only slows the load and does not act as a brake; the piston will drift if air pressure drops. To hold a load securely during air loss or valve centering, install an external rod lock or pilot-operated check valve. The 1/4 inch port and U flat-end back cover make integration straightforward.
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 MFC32X15SU FAQ
This 32 mm bore double-acting cylinder features a 1/4 inch air port and an M10x1.25 male rod 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 the end of stroke to reduce shock; it is not a brake. The piston will drift on air loss. For vertical loads, you must add an external rod lock or pilot check valve. The -S magnet allows CMSG/DMSG/EMSG sensors to track position.
