Airtac MF32-40 Stainless Steel Mini Cylinder MF32X70SUTC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X70SUTC is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 70mm 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 MF32X70SUTC
Delivering 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore pneumatic 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. For the same 70 mm stroke, the MF envelope is physically shorter than an ISO 6432 cylinder, delivering a tangible packaging win for tight machine fixtures.
The piston relies on a heterogeneous two-way seal that retains an oil film for long service life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts. Because the code includes an S, the cylinder has a built-in piston magnet ready for CMSG, DMSG or EMSG position switches. Plan for roughly 241 N of actual work at 0.5 MPa, which translates to lifting about 20.5 kg vertically with a 2:1 safety margin. Air connects via a 1/4 inch port, and the rod features an M10x1.25 male thread.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X70SUTC Is Used
Component Clamping
Secures aluminium machining blanks inside CNC fixturing, utilising the 402.2 N push force to lock parts firmly against a hard stop before milling operations begin.
Package Diverting
Actuates a routing gate on a packaging line to sort cartons, where the shorter JIS body length prevents the cylinder from intruding into adjacent walkways.
Vertical Lift Stops
Raises a lightweight pallet stopper blade weighing under 20 kg, safely managed within the 20.5 kg vertical lift capacity calculated at a 2:1 safety margin.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X70SUTC the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MF25 drops the 0.5 MPa push force to 245.3 N, whereas stepping up to the MF40 raises it to 628.3 N. This model carries a U flat-end back cover and pairs with a TC trunnion mount, giving you a pivot option that accommodates slight misalignment. The integrated magnet (-S) enables solid-state or reed sensor tracking along the SUS304 barrel.
Remember that a standard cylinder drifts if air pressure drops or the valve is centred; the TPU bumpers only decelerate the stroke end and act purely as impact absorbers, never as a braking mechanism. If your fixture must absolutely hold a vertical load during an air loss event, install an external rod lock or a pilot-operated check valve. At a 70 mm stroke, side-load stress on the 12 mm rod is minimal, but always verify that your mounting geometry prevents lateral binding.
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 MF32X70SUTC FAQ
This 32 mm bore cylinder uses a 1/4 inch air port and an M10x1.25 male rod thread. At 0.5 MPa it generates 402.2 N of push force and 345.6 N of pull force. At 0.7 MPa the push increases to 563 N and the pull to 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
It features a JIS-standard round body that is physically shorter than an ISO 6432 cylinder for the same 32 mm bore and 70 mm stroke, saving valuable mounting length. Stroke deceleration is handled by fixed TPU bumper pads rather than an adjustable air cushion. The included U flat-end back cover and TC trunnion mounting provide flexible installation options.
