Airtac MF32-40 Stainless Steel Mini Cylinder MF32X550SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X550SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 550mm 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 MF32X550SCM
Generating 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder features a 32 mm bore and a 550 mm stroke. Because 550 mm exceeds the 500 mm standard maximum, this specific unit is supplied as a non-standard, made-to-order configuration. The SUS304 stainless-steel barrel is joined to aluminium covers via a riveted rolling-packed structure, resisting mild corrosion and washdown environments while keeping the overall body shorter than a comparable ISO 6432 cylinder. The piston relies on a two-way oil-retaining seal for long life, and fixed TPU bumper pads soften the stroke-end impact. The rear of this model features a CM round-end cover, and the integrated -S piston magnet enables position sensing.
For practical sizing, plan for roughly 241 N of real work at 0.5 MPa, which safely accounts for friction and dynamic loads. This translates to lifting a 20.5 kg mass vertically with a 2:1 safety margin. Air connects via a 1/4" port, driving the 12 mm rod at speeds between 30 and 800 mm/s. Keep in mind the fixed bumpers only decelerate the end of travel; they do not function as an adjustable air cushion.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X550SCM Is Used
Extended-Reach Diverting
Pushes packages across a wide sorting conveyor using the full 550 mm travel, applying 402.2 N of thrust to redirect heavier cartons at 0.5 MPa.
Vertical Tier Elevation
Lifts components weighing up to 20.5 kg between storage shelves, utilizing the built-in -S magnet to trigger CMSG sensors at the upper transfer height.
Long-Stroke Clamping
Secures oversized automotive castings inside a machining cell, taking advantage of the SUS304 barrel to withstand occasional coolant washdown.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X550SCM the Right Cylinder?
When sizing this 32 mm bore unit, stepping down to the MF25 reduces the 0.5 MPa push force to 245.3 N, while moving up to the MF40 increases it to 628.3 N. This 550 mm configuration is a non-standard made-to-order stroke, so verify extended rod deflection and side-load limits to prevent premature seal wear over the long travel distance. The included -S magnet allows direct mounting of CMSG, DMSG, or EMSG reed and electronic sensors for end-position confirmation. For mounting flexibility, the body accepts LB foot, FA flange, SDB pivot, and TC trunnion brackets alongside the installed CM round-end rear cover.
If your process requires the rod to stay put after a valve centres or air pressure drops, this cylinder will drift. The TPU bumpers only absorb end-of-stroke kinetic energy, acting as neither a brake nor a lock. To suspend a load safely mid-stroke, incorporate an external pilot-operated check valve or a dedicated rod lock mechanism into your pneumatic circuit.
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 MF32X550SCM FAQ
At 0.5 MPa this 32 mm bore cylinder pushes with 402.2 N and pulls with 345.6 N. 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. Air is supplied through a 1/4" port, and the 12 mm piston rod features an M10x1.25 male thread.
No, the base MF uses fixed TPU bumper pads that merely decelerate the stroke end; it lacks the adjustable air cushion found in the MFC variant. Additionally, the cylinder cannot hold a load if air is lost, as the piston will drift. You must add an external rod lock or pilot check valve for position holding. The CM round-end rear cover and JIS round-body design also make the unit shorter than an ISO 6432 cylinder of the same bore and stroke.
