Airtac MF32-40 Stainless Steel Mini Cylinder MF32X620SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X620SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 620mm 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 MF32X620SCA
Generating 402.2 N of push force at 0.5 MPa, this double-acting 32 mm bore mini cylinder handles demanding positioning tasks. The 620 mm travel length exceeds the 500 mm standard catalog limit, making this specific unit a made-to-order configuration. Because the MF series follows JIS dimensions, the overall body is noticeably shorter than a comparable ISO 6432 cylinder, saving valuable mounting space in tight machinery.
The SUS304 stainless steel barrel and riveted rolling-packed aluminium covers resist mild corrosion and washdown environments. Fixed TPU bumper pads and a front-cover anti-impact pad soften the end-of-stroke impact, though they decelerate rather than provide adjustable cushioning. The piston relies on a two-way oil-retaining seal for long service life. For practical sizing, plan for roughly 241 N of actual work at 0.5 MPa, which safely lifts about 20.5 kg vertically with a 2:1 margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X620SCA Is Used
Carton Pusher Diversion
Uses the 402.2 N push force to deflect heavy packaged goods across a transfer belt at 0.5 MPa operating pressure.
Vertical Pallet Lift
Raises lightweight pallet bases using the 620 mm travel, relying on the CA pivot to accommodate frame misalignment.
Textile Beam Indexing
Shifts large textile beams along a production line where the shorter JIS body prevents interference with moving frames.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X620SCA the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MF25 yields 245.3 N at 0.5 MPa, while moving up to the MF40 provides 628.3 N. The built-in magnet (-S) supports CMSG, DMSG, and EMSG position switches. This unit features a CA rear pivot cover, ideal for angular load alignment. Because the 620 mm stroke is exceptionally long, carefully manage side loads to prevent rod bending and premature seal wear.
Air pressure alone will not maintain this cylinder's position if supply drops or the valve centres; the piston will drift. The fixed bumpers only soften the stroke end and do not act as a braking mechanism. To suspend a load safely, install an external rod lock or a pilot-operated check valve.
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 MF32X620SCA FAQ
This 32 mm bore double-acting cylinder pushes at 402.2 N and pulls at 345.6 N at 0.5 MPa. At 0.7 MPa, push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. It uses a 1/4" air port and an M10x1.25 male rod thread.
No. The CA pivot allows angular movement, and the fixed TPU bumper pads only decelerate the piston near the stroke end. They do not function as a lock. If air is lost, the piston drifts. You must add an external rod lock or pilot check valve to hold a load vertically.
