Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X45SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X45SU is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 45mm 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 MFC32X45SU
Delivering 402.2 N of push force at 0.5 MPa, this 32 mm bore double-acting mini cylinder relies on a needle-set variable air cushion at both ends to soak up high-speed end-of-stroke shock. The riveted SUS304 stainless barrel and aluminium covers resist mild corrosion and washdown, while the U flat-end rear cover streamlines tail mounting. Because the -S suffix equips the piston with a built-in magnet, the unit is ready for CMSG, DMSG or EMSG position switches.
For the same 32 mm bore and 45 mm stroke, the JIS-standard round body is noticeably shorter than an ISO 6432 cylinder, saving valuable machine space without sacrificing the 1/4" port or M10x1.25 male rod thread. It handles speeds of 30-800 mm/s across a 0.15-1.0 MPa pressure range. Based on the 0.5 MPa thrust, a safe working load is roughly 241 N, lifting about 20.5 kg vertically with a 2:1 safety margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X45SU Is Used
Light Press Assembly
Drives a 240 N insertion head rapidly downward, using the variable air cushion to decelerate the tooling gently before it bottoms out.
Package Diverting
Pushes 20 kg cartons off a high-speed belt, relying on the 402.2 N push force and end cushions to absorb the repetitive impact.
Vertical Lift Gates
Hoists lightweight access doors in humid washdown zones where the SUS304 barrel prevents mild corrosion and the U cover mounts flush.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X45SU the Right Cylinder?
If 245.3 N from the smaller MFC25 is insufficient, this 32 mm bore steps up the thrust to 402.2 N at 0.5 MPa; should your payload require even more force, the larger MFC40 provides 628.3 N. The adjustable air cushion is essential when moving heavy loads at high velocity, as it decelerates the piston smoothly to protect the workpiece. Note that the cushion only slows the rod near the end of travel and does not act as a brake; the piston will drift on air loss or when the valve is centred, so fit an external rod lock or pilot-operated check valve if you need to hold a suspended load. The -S magnet allows solid-state or reed sensor tracking, and the flat U back cover suits flush installations.
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 MFC32X45SU FAQ
This 32 mm bore cylinder features a 1/4" port and an M10x1.25 male rod thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, increasing to 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 stroke end and never acts as a lock or brake; the rod will drift if air is lost. For suspended loads, install an external rod lock or pilot check valve. The -S magnet supports CMSG, DMSG and EMSG sensors for position feedback.
