Airtac MF32-40 Stainless Steel Mini Cylinder MF40X45CA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X45CA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 45mm 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 MF40X45CA
Delivering 628.3 N of push force at 0.5 MPa, this 40 mm bore double-acting mini cylinder handles heavy-duty positioning in tight spaces. The JIS-standard round body is physically shorter than an ISO 6432 cylinder of the same bore and stroke, delivering a noticeable packaging advantage. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown environments. Plan for around 377 N of actual work at 0.5 MPa, which means you can vertically lift roughly 32 kg safely with a 2:1 margin.
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. This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG reed switches. The 1/4" port and M14x1.5 male rod thread accommodate robust pneumatic supply and mechanical coupling. It features a CA pivot back cover for articulated rear mounting.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X45CA Is Used
Stamping Press Ejection
Uses the 527.8 N pull force at 0.5 MPa to swiftly extract heavy metal blanks from a stamping die before the next cycle begins.
Pallet Diverting Arm
Leverages the CA pivot back cover to swing a heavy lane deflector, routing loaded pallets on a high-speed packaging line.
Heavy Carton Lid Press
Applies brief, high downward pressure to secure oversized shipping carton flaps before adhesive setting.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X45CA the Right Cylinder?
When sizing this 40 mm bore unit, verify your force requirements carefully. If 628.3 N at 0.5 MPa is excessive, step down to the MF32, which provides 402.2 N; since 40 mm is the largest available MF bore, exceeding this capacity requires a different cylinder family entirely. The short 45 mm stroke minimizes rod-bending side loads, making it highly stable for brief, powerful clamping actions.
Because this is a base double-acting cylinder, the piston will drift if air pressure drops or the valve is centred—the fixed bumpers only decelerate the stroke end and do not function as a locking brake. To suspend a load safely during an air loss event, install an external rod lock or a pilot-operated check valve. Note that without the -S magnet option, position sensing is not possible on this unit.
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 MF40X45CA FAQ
This 40 mm bore cylinder features a 1/4" port and an M14x1.5 male rod thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum of 128.1 kgf at 1.0 MPa.
The CA back cover provides a pivot mount for articulated rod-end loads. Fixed TPU bumper pads decelerate the piston at stroke ends but do not act as an adjustable air cushion (see the MFC variant for that). The SUS304 stainless build is shorter than an ISO 6432 cylinder, saving mounting length.
