Airtac MF32-40 Stainless Steel Mini Cylinder MF32X680SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X680SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 680mm 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 MF32X680SCM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles substantial work despite its compact footprint. The 680 mm stroke exceeds the 500 mm standard limit, making this specific unit a non-standard, made-to-order configuration. Because the SUS304 stainless-steel barrel and riveted aluminium covers yield a body shorter than an equivalent ISO 6432 cylinder, you reclaim valuable mounting length in tight machine envelopes.
The riveted rolling-packed structure shrugs off mild corrosion and washdown environments, while the piston's heterogeneous two-way seal retains an oil film for extended mechanical life. Fixed TPU bumper pads and a front-cover anti-impact pad soften the stroke-end impact. For practical sizing, plan your payload around 241 N of real work at 0.5 MPa, which translates to lifting roughly 20.5 kg vertically with a 2:1 safety margin. The 1/4" port and M10x1.25 male rod thread accommodate robust airflow, and the built-in -S magnet supports CMSG, DMSG, or EMSG position switches.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X680SCM Is Used
Long-Reach Vertical Pressing
Deploys the 680 mm stroke to press components deep into a machining fixture, using the 402.2 N push force at 0.5 MPa to seat parts securely.
Extended Transfer Routing
Pushes workpieces across wide conveyor gaps in packaging lines, where the shorter JIS body prevents interference with adjacent moving machinery.
High-Bay Ejection
Ejects packed cartons from elevated sorting chutes, relying on the SUS304 stainless barrel to withstand dusty, mildly humid warehouse conditions.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X680SCM the Right Cylinder?
When sizing this 32 mm bore, compare it directly against its neighbours: the MF25 provides 245.3 N of push at 0.5 MPa for lighter duties, while stepping up to the MF40 yields 628.3 N for heavier payloads. Because this 680 mm unit is a non-standard made-to-order stroke that significantly exceeds the 500 mm standard maximum, pay close attention to rod-bending moments and side loads—ensure external guidance supports the extended rod to prevent premature seal wear. The CM round-end back cover suits rear pivot mounting arrangements.
Remember that fixed TPU bumpers only decelerate the end of travel; they do not function as a lock. If air pressure drops or the valve centres, the piston will drift, so integrate an external rod lock or a pilot-operated check valve whenever you need to suspend a load safely. Operating speed ranges from 30-800 mm/s across a 0.15-1.0 MPa pressure range.
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 MF32X680SCM FAQ
This 32 mm bore double-acting cylinder delivers 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. It uses a 1/4" air port and an M10x1.25 male piston rod thread.
The CM designation indicates a round-end rear cover ideal for pivot mounting. The fixed TPU bumper pads only decelerate the stroke end and do not act as a brake; if air is lost, the piston will drift. You must use an external rod lock or pilot check valve to hold a vertical load safely.
