Airtac MF32-40 Stainless Steel Mini Cylinder MF40X40SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X40SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 40mm 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 MF40X40SCA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty tasks within tight fixtures. Because the MF body is shorter than a comparable ISO 6432 unit for the same 40 mm bore and 40 mm stroke, it saves valuable mounting length. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments.
The piston relies on a two-way oil-retaining seal to maintain lubrication, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts. Plan for roughly 377 N of actual work at 0.5 MPa, which means it can vertically lift about 32 kg with a 2:1 safety margin. This specific SKU includes a built-in magnet for position sensing and uses a 1/4 inch port.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X40SCA Is Used
Clamp Actuation
Secures heavy cast metal parts in CNC machining centres, utilizing the 628.3 N push force to hold workpieces firmly against the fixture stops.
Vertical Pressing
Pushes bearings or pins into housings on an automated assembly line, safely lifting or pressing up to 32 kg with a 2:1 safety margin.
Pallet Diverter
Extends a guide rail to redirect loaded pallets on a packaging conveyor, relying on the compact JIS body to fit within restrictive frame gaps.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X40SCA the Right Cylinder?
When sizing this 40 mm bore, moving down to the MF32 drops the 0.5 MPa push force to 402.2 N, while the 40 mm bore is the largest available in the MF series at 628.3 N. If your application loses air pressure or the valve is centred, the piston will drift and drop the load, as the TPU pads only decelerate the stroke end rather than locking the rod. To suspend a vertical load safely, install an external rod lock or a pilot-operated check valve.
This model features the CA rear pivot cover for clevis mounting, and the included -S magnet allows you to attach CMSG, DMSG, or EMSG switches for end-of-stroke detection. With a 40 mm stroke, keep side loading minimized to prevent rod bending and premature seal wear.
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 MF40X40SCA FAQ
This 40 mm bore cylinder features a 1/4 inch port and an M14x1.5 male rod thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum force of 128.1 kgf at 1.0 MPa.
It is a JIS-standard round-body cylinder that is physically shorter than an ISO 6432 cylinder for the same bore and stroke, but it does not conform to ISO 6432. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake, so the piston will drift if air is lost; use a pilot check valve for vertical holding.
