Airtac MF32-40 Stainless Steel Mini Cylinder MF32X200SU
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X200SU is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 200mm 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 MF32-40 Stainless Steel Mini Cylinder MF32X200SU
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder is engineered for tight machinery layouts. For the same 32 mm bore and 200 mm stroke, the MF body is noticeably shorter than a comparable ISO 6432 unit, providing a tangible packaging advantage in dense fixtures. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments.
It features a 1/4 inch port and a U flat-end back cover. Because the piston seal retains an oil film, friction stays low over long life. Plan for roughly 241 N of actual work at 0.5 MPa, which means you can safely lift about 20.5 kg vertically with a 2:1 safety margin. The built-in magnet (-S) supports CMSG, DMSG and EMSG switches, while fixed TPU bumper pads soften the stroke-end impact.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X200SU Is Used
Package Diverting
Actuates a routing gate on a packaging conveyor, using the 200 mm stroke to push cartons cleanly into secondary lanes.
Vertical Parts Lift
Raises lightweight tote bins weighing up to 20 kg in a compact goods-to-person station, saving mounting length over ISO 6432 units.
Clamp Actuation
Extends a holding clamp on an aluminium machining fixture, applying 402.2 N of push force to secure the part during milling.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X200SU the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MF25 yields 245.3 N of push force at 0.5 MPa, whereas stepping up to the MF40 provides 628.3 N. If your process requires the rod to hold a vertical load when air is removed or the valve is centred, this standard cylinder will drift; you must integrate an external rod lock or a pilot-operated check valve. The 200 mm stroke is well within the 500 mm standard limit, but at this length you should minimize side loading to prevent rod bending and premature seal wear. Mounting options include LB foot, FA flange, SDB pivot and TC trunnion to suit your frame.
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 MF32-40 Stainless Steel Mini Cylinder MF32X200SU FAQ
This 32 mm bore cylinder has a 1/4 inch 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.
The U suffix denotes a flat-end back cover. It uses fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion. The S suffix means it has a built-in magnet for CMSG, DMSG or EMSG switches; without the S, a sensor cannot be fitted.
