Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X500SU
The AirTAC Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X500SU is a genuine double acting + cushion JIS-standard round-body mini air cylinder with a Ø32mm bore and 500mm 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 MFC32X500SU
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MFC32X500SU is a double-acting JIS-standard round-body mini cylinder built for long-reach tasks. It features a SUS304 stainless steel barrel with riveted aluminium covers, resisting mild corrosion and washdown environments. Because the MF body is shorter than an ISO 6432 cylinder for the same bore and stroke, it saves valuable mounting length on a 500 mm extension. The U flat-end rear cover provides a straightforward flush mounting face.
A defining trait of this MFC series is the variable air cushion at both ends. By turning a needle valve, you tune the deceleration to soak up high-speed shock at stroke completion, protecting the load and cutting noise versus a fixed bumper. This unit includes the -S piston magnet for CMSG, DMSG or EMSG switches, and uses a 1/4" port with an M10x1.25 male rod thread. For a practical guideline, its safe working load is about 241 N, or it lifts roughly 20.5 kg vertically with a 2:1 margin.

Where the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X500SU Is Used
Long-Stroke Diverting
Pushes packages across a wide conveyor belt over 500 mm, using the tuned air cushion to stop the 402.2 N thrust smoothly without slamming.
Vertical Lift Gates
Raises lightweight access gates up to 20.5 kg, relying on the SUS304 stainless barrel to withstand humid or washdown warehouse conditions.
Shock-Sensitive Indexing
Moves delicate tooling heads at speed, using the adjustable end cushions to decelerate the 12 mm rod gently before the U flat-end cover bottoms out.
Is the Airtac MFC Cushioned Stainless Steel Mini Cylinder MFC32X500SU the Right Cylinder?
When sizing this 32 mm bore, evaluate both directions: the MFC25 provides 245.3 N at 0.5 MPa if your load is lighter, while the MFC40 offers 628.3 N for heavier demands. The variable air cushion is essential when cycling at high speeds or moving substantial mass over the full 500 mm travel, as it prevents harsh end-of-stroke impacts. Remember that the cushion only decelerates the piston near the end of the stroke; it does not function as a lock or brake. If the application must hold a load vertically during air loss or when a valve is centered, add an external rod lock or a pilot-operated check valve to prevent drift. You can mount this unit via LB foot, FA flange, SDB pivot or TC trunnion hardware.
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 MFC32X500SU FAQ
This double-acting 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 force of 82 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the valve is centered. The variable air cushion only decelerates the rod near the stroke end and acts purely as a shock absorber, never as a lock or brake. You must use an external rod lock or pilot check valve to hold a suspended load.
