Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X40U
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X40U is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 40mm 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 MFC32X40U
Delivering 402.2 N of push force at 0.5 MPa, this 32 mm bore double-acting mini cylinder handles demanding cycles with precision. A needle-set variable air cushion at both ends absorbs end-of-stroke shock at high speeds, protecting your payload far better than a fixed bumper. The SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown environments.
For the same bore and stroke, the JIS-standard round-body design is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length. Driven by a 1/4 inch port and a 12 mm rod, it yields a safe working load of roughly 241 N, lifting about 20.5 kg vertically with a 2:1 margin. This specific U-flat-end rear cover variant lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X40U Is Used
Package Diverting
Uses the 402.2 N thrust to push parcels cleanly off a high-speed belt, relying on the variable air cushion to stop the 40 mm stroke without slamming.
Carton Sealing Press
Drives a sealing head down onto boxes, where the adjustable needle cushions the impact to protect flaps and adhesives from crushing.
Light Milling Clamp
Holds aluminium parts for machining, providing a stable 241 N safe working load while the compact JIS body fits tight machining cells.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X40U the Right Cylinder?
When sizing this 32 mm bore, step down to the MFC25 for 245.3 N @0.5 MPa if loads are lighter, or move up to the MFC40 for 628.3 N @0.5 MPa when you need 628.3 N of thrust. The adjustable air cushion is essential when operating at high speeds or moving heavy masses, letting you dial in the exact deceleration to prevent end-of-stroke banging.
Remember that the cushion only decelerates the piston near the stroke end; it is not a brake. If air pressure drops, the piston will drift, so fit an external rod lock or pilot-operated check valve for secure load holding. Since this SKU has no magnet, order an -S variant if you require position sensing.
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 MFC32X40U FAQ
This 32 mm bore cylinder uses a 1/4 inch port. 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. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, this specific SKU lacks a piston magnet and cannot accept CMSG, DMSG, or EMSG switches. You must order the -S variant for sensing. The SUS304 stainless build resists mild corrosion, and the U-type flat-end rear cover allows direct mounting.
