Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X85SUTC
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X85SUTC is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 85mm 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 MFC32X85SUTC
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MFC32X85SUTC is a JIS-standard round-body mini cylinder built for double-acting service. It features a SUS304 stainless barrel with riveted aluminium covers, resisting mild corrosion and washdown environments. For the same 32 mm bore and 85 mm stroke, this riveted body is notably shorter than an ISO 6432 cylinder, saving valuable mounting length.
A defining trait of the MFC series is the variable air cushion at both ends. By turning the cushion needle, you tune the end-of-stroke deceleration to absorb high-speed shock, protecting the load and cutting noise. The -S suffix adds a piston magnet for CMSG, DMSG or EMSG sensors, while the U flat-end back cover and TC trunnion mount support pivoting layouts. Derived from 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 MFC32X85SUTC Is Used
Package Diverting
Uses the 241 N safe working load to push parcels smoothly onto side lanes, relying on the tuned air cushion to stop the rod gently at high cycle rates.
Light Press Fit
Applies the 402.2 N @0.5 MPa thrust to seat small bearings, with the TC trunnion absorbing slight misalignment during the pressing motion.
Vertical Lift Stops
Raises roughly 20.5 kg of stock using the 2:1 margin, where the U flat-end rear cover and variable cushion prevent harsh drops at the top of the 85 mm stroke.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X85SUTC the Right Cylinder?
When sizing this 32 mm bore, step down to the MFC25 for 245.3 N @0.5 MPa if your load is lighter, or move up to the MFC40 for 628.3 N @0.5 MPa when you need heavier thrust. The adjustable air cushion matters most when driving high-speed strokes or shifting inertial loads, letting you dial out end-of-stroke banging without adding external shock absorbers.
Remember that the cushion only decelerates the piston near the stroke end; it is not a brake. If air drops or the valve centres, the rod drifts, so fit an external rod lock or pilot check valve to hold a suspended load. The 1/4" port matches the bore size, and the integrated magnet (-S) works directly with CMSG, DMSG and EMSG switches.
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 MFC32X85SUTC FAQ
This 32 mm bore cylinder has 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, 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 the stroke; it is not a lock or brake. If air drops, the rod drifts. For vertical loads, install an external rod lock or pilot-operated check valve. The SUS304 barrel resists washdown, and the -S magnet supports CMSG, DMSG or EMSG sensors.
