Airtac MF32-40 Stainless Steel Mini Cylinder MF32X375SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X375SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 375mm 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 MF32X375SCM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore AirTAC mini cylinder tackles demanding positioning tasks. Because the JIS-standard round body is physically shorter than a comparable ISO 6432 unit, it saves valuable mounting length in tight machinery. The SUS304 stainless barrel and riveted aluminium covers shrug off mild corrosion, while the two-way piston seal retains an oil film for extended mechanical life.
Equipped with a built-in magnet for CMSG, DMSG or EMSG sensors, this unit also features a CM round-end rear cover for pivot mounting. 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. The 1/4 inch port feeds the 12 mm rod, and fixed TPU bumper pads absorb the impact at stroke extremes without acting as an adjustable cushion.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X375SCM Is Used
Pallet Diverting Gate
Actuates a routing flap on a packaging line, using the 402.2 N push force to nudge heavy cartons onto a secondary track at high cycling speeds.
Vertical Parts Lift
Raises lightweight component trays between conveyor tiers, safely lifting payloads up to 20.5 kg with a 2:1 safety margin during transfer operations.
Clamp Actuation
Secures aluminium extrusions in a machining fixture, relying on the compact JIS body length to fit within a dense multi-tool CNC envelope.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X375SCM the Right Cylinder?
If your fixture requires less push, the MF25 provides 245.3 N at 0.5 MPa; stepping up to the MF40 yields 628.3 N for heavier payloads. At a 375 mm stroke, minimizing side loading is critical to prevent rod bending, so guide the load externally rather than relying on the piston rod. This SKU includes the -S magnet for position sensing and the CM round-end back cover. Remember that air pressure alone will not hold a load if supply drops or the valve centres, as the piston will drift; integrate a pilot check valve or external rod lock for secure positioning.
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 MF32X375SCM FAQ
This 32 mm bore cylinder features a 1/4 inch port and a 12 mm rod. 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.
No, the base MF uses fixed TPU bumper pads to decelerate at the stroke end, not an adjustable air cushion; for variable damping look at the MFC variant. Additionally, it will not hold a load if air is lost, so you need an external rod lock or pilot check valve for position holding.
