Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X125U
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X125U is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 125mm 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 MFC32X125U
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MFC32X125U is a JIS-standard round-body mini cylinder built for double-acting operation. It features a SUS304 stainless barrel with riveted aluminium covers, resisting mild corrosion and washdown environments. For the same bore and stroke, this riveted body is noticeably shorter than an ISO 6432 cylinder, saving valuable mounting length. This specific U-style configuration includes a flat-end rear cover for direct rear mounting.
The defining feature is the variable air cushion at both ends. By turning a needle valve, you tune the end-of-stroke deceleration to soak up high-speed shock, protecting the load and cutting noise versus a simple bumper. This base SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors; order the -S variant if position sensing is required. Based on the 0.5 MPa push rating, it handles a safe working load of about 241 N, lifting roughly 20.5 kg vertically with a 2:1 margin. The 1/4" port and M10x1.25 male rod thread match the 32 mm bore class.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X125U Is Used
Package Diverting
Handles 20.5 kg cartons at high cycle rates on a sorting line, using the tuned air cushions to silently absorb the 125 mm stroke impacts without jarring the conveyor frame.
Light Press Fit
Applies up to 402.2 N of push force at 0.5 MPa to seat small bearings, relying on the flat-end U cover for stable rear mounting against the machine bulkhead.
Vertical Lift Gate
Raises and lowers a 241 N access flap, requiring an external pilot check valve to prevent drifting down, as the cylinder cushions cannot lock the load in place.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X125U the Right Cylinder?
When sizing this 32 mm bore, compare it both ways: step down to an MFC25 for 245.3 N at 0.5 MPa if your load is lighter, or step up to an MFC40 for 628.3 N at 0.5 MPa if you need more thrust. The adjustable air cushion is essential when cycling at high speeds or moving heavy masses, preventing harsh end-of-stroke impacts. Remember that the cushion only decelerates the piston near the stroke end; it does not function as a brake. If the application must hold a load vertically during air loss or valve centering, the piston will drift, so you must fit an external rod lock or pilot-operated check valve. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion, while this U version provides a flat rear cover.
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 MFC32X125U FAQ
This 32 mm bore double-acting cylinder pushes 402.2 N and pulls 345.6 N at 0.5 MPa. At 0.7 MPa it pushes 563 N and pulls 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. It uses a 1/4" air port and a 12 mm rod with an M10x1.25 male thread.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You must select the -S variant for position sensing. Additionally, the SUS304 stainless build and variable air cushions handle high-speed washdown duty, but the cushions only decelerate the load, they do not hold it.
