Airtac MF32-40 Stainless Steel Mini Cylinder MF40X160SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X160SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 160mm 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 MF40X160SCA
Delivering 628.3 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles heavy-duty positioning tasks. The SUS304 stainless steel barrel and riveted aluminium covers resist mild corrosion and washdown environments. Because the MF body is shorter than a comparable ISO 6432 unit for the same 40 mm bore and 160 mm stroke, it saves valuable mounting length in tight machinery. The piston relies on a two-way oil-retaining seal for long life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts.
Featuring a built-in piston magnet, this unit supports CMSG, DMSG, and EMSG switches for position sensing. Plan for roughly 377 N of actual work at 0.5 MPa, which translates to lifting about 32 kg vertically with a 2:1 safety margin. The 1/4" port and M14x1.5 male rod thread accommodate robust pneumatic flow and sturdy mechanical attachments. This configuration includes a CA pivot back cover for articulated rear mounting.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X160SCA Is Used
Press Fit Subassemblies
Drives small bushings or bearings into housings on an automated machining line, utilizing the 628.3 N push force to seat parts reliably.
Heavy Package Diverting
Actuates a pivoting gate arm to redirect dense cartons on a logistics sorting conveyor, where the CA pivot mount absorbs structural shock.
Pallet Lift Gates
Raises and lowers an ergonomic access gate on a packaging workstation, lifting roughly 32 kg of aluminum framing with a safe 2:1 margin.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X160SCA the Right Cylinder?
When sizing this 40 mm bore, compare it directly against the smaller MF32, which provides 402.2 N of push at 0.5 MPa. Since 40 mm is the largest available bore in the MF series, moving beyond 628.3 N requires a different cylinder family. For this 160 mm stroke, ensure your front mounting resists rod-bending side loads, as longer strokes amplify lateral forces. The CA pivot back cover pairs well with trunnion or clevis mounts to absorb misalignment.
Remember that a standard double-acting cylinder drifts when air is lost or the valve is centred; the TPU bumpers only decelerate the stroke end and do not function as a brake. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve into your 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 MF40X160SCA FAQ
At 0.5 MPa it pushes 628.3 N and pulls 527.8 N. At 0.7 MPa it pushes 879.6 N and pulls 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa. This 40 mm bore cylinder uses a 1/4" air port.
Yes, the -S suffix denotes a built-in piston magnet compatible with CMSG, DMSG, and EMSG switches. The CA back cover provides a rear pivot point, allowing the cylinder to articulate smoothly on a clevis pin, which is ideal for mechanisms with slight angular movement.
