Airtac MF32-40 Stainless Steel Mini Cylinder MF32X25SUTC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X25SUTC is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 25mm 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 MF32X25SUTC
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MF32X25SUTC is a JIS-standard round-body mini cylinder built for tight machinery. Its SUS304 stainless steel barrel and riveted aluminium covers shrug off mild washdown environments. Because the MF body is shorter than a comparable ISO 6432 unit for the same 32 mm bore and 25 mm stroke, it trims valuable mounting length from your fixtures.
This double-acting actuator breathes through a 1/4" port and relies on fixed TPU bumper pads to soften stroke-end impacts. The piston employs a two-way oil-retaining seal for long service life. Plan for a safe working load of roughly 241 N, which means you can vertically lift about 20.5 kg with a 2:1 safety margin. The built-in magnet supports CMSG, DMSG, and EMSG position switches.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X25SUTC Is Used
Short-Stroke Clamping
Ideal for locking aluminium extrusions in CNC machining fixtures where the 402.2 N push force and 25 mm travel secure parts without consuming valuable Z-axis height.
Package Diverting
Snaps a 20.5 kg carton laterally across a packaging line; the compact JIS body fits neatly between conveyor rollers while the U flat-end cover handles rear impacts.
Component Insertion
Presses small bearings into housings on an automated assembly table, using the integrated magnet and a DMSG sensor to confirm the 25 mm insertion depth instantly.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X25SUTC the Right Cylinder?
When sizing this 32 mm bore, stepping down to an MF25 yields 245.3 N at 0.5 MPa, while stepping up to an MF40 provides 628.3 N. This model includes a U-style flat-end back cover and a TC trunnion mount for pivoting frameworks. If your process loses air or the valve centres, the piston will drift; these bumper pads only decelerate the end of travel and do not function as a brake. To suspend a load securely, install an external rod lock or a pilot-operated check valve.
With a brief 25 mm stroke, side-load stress on the 12 mm rod is minimal, but always verify that your TC trunnion mounting points align squarely to prevent 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 MF32X25SUTC FAQ
This 32 mm bore cylinder features a 1/4" port and an M10x1.25 male rod thread. At 0.5 MPa it pushes with 402.2 N and pulls with 345.6 N. At 0.7 MPa the push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
The JIS-standard MF body is physically shorter than an ISO 6432 cylinder for the same bore and stroke, saving mounting space. It uses fixed TPU bumper pads to decelerate at the stroke end rather than an adjustable air cushion. The SUS304 stainless barrel resists mild corrosion, and the included -S magnet allows CMSG, DMSG, or EMSG sensors to track position.
