Airtac MF32-40 Stainless Steel Mini Cylinder MF40X33SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X33SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 33mm 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 MF40X33SCA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting AirTAC MF40X33SCA handles heavy-duty positioning in tight machinery. The JIS-standard round-body construction is physically shorter than a comparable ISO 6432 cylinder for the same 33 mm stroke, yielding a measurable packaging advantage. Its SUS304 stainless steel barrel and riveted aluminium covers naturally resist mild corrosion and washdown environments.
The bore-fixed 1/4" port and M14x1.5 male rod thread accommodate robust pneumatic flow for rapid cycling. Plan for roughly 377 N of actual work at 0.5 MPa to maintain a safe margin, which translates to lifting about 32 kg vertically against gravity. Fixed TPU bumper pads and a front-cover anti-impact pad absorb the stroke-end shock, while the integrated -S magnet enables CMSG, DMSG, or EMSG switches for position sensing.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X33SCA Is Used
Press Pin Insertion
Drives dowel pins into heavy steel jigs using its 628.3 N thrust, relying on the compact JIS body to fit between dense tooling columns.
Pallet Diverter Arm
Actuates a heavy routing gate on a packaging line, where the CA pivot back cover absorbs lateral sway during high-speed product sorting.
Vertical Parts Lift
Raises 30 kg hardware totes vertically in an assembly cell, staying safely within the 32 kg calculated lift margin at 0.5 MPa.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X33SCA the Right Cylinder?
When sizing this 40 mm bore unit, compare its 628.3 N push force at 0.5 MPa against the smaller MF32, which provides 402.2 N. Since 40 mm is the largest available MF bore, moving beyond this capacity requires a different cylinder family entirely. The included CA pivot back cover is ideal for clevis mounting, and you can pair it with LB foot, FA flange, SDB pivot, or TC trunnion brackets depending on your frame.
Because this is a double-acting cylinder, air drives the piston in both directions, but it will drift if air pressure drops or the valve is centred. The fixed bumpers only decelerate the end of travel and do not function as a brake. For suspended loads that must remain stationary during air loss, install an external rod lock or a pilot-operated check valve.
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 MF40X33SCA FAQ
At 0.5 MPa it pushes with 628.3 N and pulls with 527.8 N. At 0.7 MPa the push is 879.6 N and pull is 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa. It uses a 1/4" air port and an M14x1.5 male piston rod thread.
The -S suffix means it has a built-in piston magnet, so you can mount CMSG, DMSG, or EMSG switches for precise position detection. However, it features fixed TPU bumper pads that decelerate the stroke end; it does not have an adjustable air cushion. For variable cushioning, look at the MFC variant.
