Airtac MF32-40 Stainless Steel Mini Cylinder MF32X85SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X85SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 85mm 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 MF32X85SCA
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore mini cylinder is built around a JIS-standard round body. Its SUS304 stainless steel barrel and riveted aluminium covers shrug off mild corrosion and washdown environments, while the internal two-way seal retains an oil film for long service life. Because the MF body is shorter than an ISO 6432 cylinder for the same 85 mm stroke, it saves valuable mounting length in tight fixtures.
The integrated piston magnet (-S) allows direct mounting of CMSG, DMSG, or EMSG reed and electronic switches for position sensing. Fixed TPU bumper pads at both ends soften the stroke-end impact, and the rear CA pivot mount simplifies angular alignment. Plan for a safe working load of roughly 241 N, which lets you lift about 20.5 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X85SCA Is Used
Package Diverting Gate
Swings a lightweight sorting gate on a packaging line, using the 85 mm stroke and CA pivot to redirect cartons smoothly without overextending into the lane.
Clamp Actuation
Secures aluminium extrusions in a CNC machining fixture, delivering 402.2 N of push force at 0.5 MPa to hold the part firmly against the stop block.
Vertical Parts Lift
Raises small component trays weighing up to 20.5 kg between conveyor tiers, relying on the integrated magnet to trigger lower-limit DMSG sensors.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X85SCA the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MF25 yields 245.3 N of push at 0.5 MPa, while stepping up to the MF40 provides 628.3 N. The 1/4" port matches the 32 mm bore specification, ensuring adequate flow for the 30-800 mm/s speed range. The CA rear pivot cover is ideal for applications requiring a pivoting rod-end trajectory.
If your process requires the load to remain suspended during a compressed air loss or valve centre state, note that this standard cylinder will drift. The fixed bumpers only decelerate the end-of-stroke impact and do not act as a brake; for secure load holding, incorporate an external pilot-operated 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 MF32X85SCA FAQ
This 32 mm bore double-acting cylinder features a 1/4" air port and an M10x1.25 male rod thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, increasing to 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, the MF is a JIS-standard round-body cylinder, not an ISO 6432 unit, though its shorter body is a packaging advantage. It uses fixed TPU bumper pads for deceleration rather than an adjustable air cushion. Mounting options include LB foot, FA flange, and TC trunnion, with this specific CA rear cover providing a pivot point.
