Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X400SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X400SU is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 400mm 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 MFC32X400SU
Tame high-speed end-of-stroke shock with the AirTAC MFC32X400SU, a JIS-standard round-body mini cylinder featuring a needle-adjustable variable air cushion at both ends. Driven by a 32 mm bore over a 400 mm stroke, it generates 402.2 N of push force and 345.6 N of pull force at 0.5 MPa. The riveted aluminium covers and SUS304 stainless barrel resist mild corrosion and washdown environments. For the same bore and stroke, this compact body is notably shorter than an ISO 6432 cylinder, saving valuable machine space.
This double-acting actuator uses a two-way oil-retaining seal and a front-cover fixed anti-impact pad to sustain smooth cycling at speeds from 30 to 800 mm/s. Derived from its 0.5 MPa push rating, it handles a safe working load of roughly 241 N and lifts about 20.5 kg vertically with a 2:1 safety margin. The U flat-end rear cover simplifies direct mounting, while the 1/4" port and M10x1.25 male rod thread ensure robust pneumatic and mechanical connections.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X400SU Is Used
Package Diverting
Pushes medium-weight cartons at high cycle rates on a sorting line, using the variable air cushion to silently absorb the 400 mm stroke impact without jarring the conveyor frame.
Light Pressing
Applies a steady 402.2 N clamping force at 0.5 MPa to seat electronic components, relying on the SUS304 barrel for washdown compatibility in cleanroom assembly zones.
Pallet Stops
Acts as a high-speed physical stop for incoming pallets, safely decelerating the 241 N safe working load via the needle-set cushion before the U flat-end cover absorbs residual energy.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X400SU the Right Cylinder?
When sizing this 32 mm bore unit, compare its 402.2 N push force at 0.5 MPa against adjacent options: step down to an MFC25 for 245.3 N, or up to an MFC40 for 628.3 N. The variable air cushion is essential for heavy or fast-moving loads, as turning the needle valve lets you precisely tune deceleration and eliminate end-thud across the 400 mm travel. Remember the cushion only decelerates the piston; it is not a brake. If your application must hold position on air loss, add an external rod lock or pilot-operated check valve.
This MFC32X400SU configuration includes the -S piston magnet, allowing seamless integration with CMSG, DMSG, or EMSG reed and electronic switches for end-position sensing. Mounting flexibility is provided through standard LB foot, FA flange, SDB pivot, and TC trunnion brackets.
Quick checklist

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 MFC32X400SU FAQ
This 32 mm bore double-acting cylinder features a 1/4" air port and an M10x1.25 male rod thread. It delivers 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 force of 82 kgf at 1.0 MPa.
It uses a needle-adjustable variable air cushion at both ends to decelerate the piston near stroke end, cutting shock at speeds up to 800 mm/s. It is not a lock or brake; if air is lost, the piston will drift. For vertical loads, install an external rod lock or pilot check valve. The -S magnet enables CMSG/DMSG/EMSG sensors.
