Airtac MF32-40 Stainless Steel Mini Cylinder MF40X200SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X200SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm 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 MF40X200SCA
Delivering 628.3 N of push force at 0.5 MPa, this 40 mm bore double-acting mini cylinder is built around a SUS304 stainless barrel with riveted aluminium covers. Because the JIS-standard body is physically shorter than an ISO 6432 cylinder of the same bore and stroke, it saves valuable mounting length in tight machinery. The 1/4" port and M14x1.5 male rod thread handle the air volume needed for high thrust.
The internal piston relies on a two-way oil-retaining seal to maintain lubrication for long service life, while fixed TPU bumper pads and a front-cover anti-impact pad absorb stroke-end shock. Plan for roughly 377 N of actual work at 0.5 MPa to keep a safe 60% capacity margin, which equates to lifting about 32 kg vertically with a 2:1 safety factor. The included -S magnet supports CMSG, DMSG, and EMSG position switches.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X200SCA Is Used
Pallet Diverter Gate
Swings heavy transfer gates on packaging lines using 628.3 N of push force, with the CA pivot absorbing lateral swing during 200 mm travel.
Stamping Press Feed
Pushes metal blanks into a forming press, relying on the SUS304 stainless barrel to withstand mild coolant washdown in the work area.
Carton Flap Folder
Folds heavy corrugated carton flaps during high-speed packing, using the integrated -S magnet to trigger CMSG sensors for precise timing.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X200SCA the Right Cylinder?
When sizing this 40 mm bore unit, step down to the MF32 if your task requires only 402.2 N of push force at 0.5 MPa, as 40 mm is the largest available bore in the MF family. For heavier payloads, splitting the load across two cylinders is required since no larger MF bore exists. The 200 mm stroke operates safely within the 500 mm standard limit, though long strokes demand careful guide alignment to prevent rod bending under side loads.
This SKU features a CA rear pivot cover for clevis mounting and an integrated -S magnet for electronic or reed sensors. Remember that standard double-acting operation means the rod will drift if air pressure drops or the valve centers; the TPU pads only decelerate the stroke end and do not function as a locking brake. To suspend a load safely mid-stroke, fit an external pilot check valve or a dedicated rod lock.
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 MF40X200SCA FAQ
This 40 mm bore cylinder uses a 1/4" port and delivers 628.3 N push and 527.8 N pull at 0.5 MPa, or 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
No, the MF is a JIS-standard round-body cylinder that is simply shorter than an ISO 6432 unit, so ISO hardware will not fit. It uses fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable air cushion; for variable cushioning, look at the MFC variant.
