Airtac MF32-40 Stainless Steel Mini Cylinder MF32X450CA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X450CA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 450mm 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 MF32X450CA
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder handles substantial work within a compact footprint. For the same 32 mm bore and 450 mm stroke, the riveted SUS304 stainless steel barrel and aluminium covers create a body noticeably shorter than an ISO 6432 unit, tightening fixture layouts. The 1/4" port feeds a two-way oil-retaining piston seal, while fixed TPU pads soften stroke-end impacts.
Plan for roughly 241 N of actual work at 0.5 MPa to maintain a safe margin, which translates to lifting about 20.5 kg vertically against gravity. Because this specific SKU lacks the -S magnet, it cannot host CMSG, DMSG, or EMSG reed switches for position sensing. The rear CA pivot cover directly accommodates articulated rod-end loads, and the front cover integrates an anti-impact pad to shield the piston from mechanical shock.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X450CA Is Used
Pallet Divertor Arm
Uses the 450 mm stroke and 402.2 N push force to swing heavy pallets onto secondary packaging lines, relying on the CA pivot to absorb angular misalignment.
Vertical Parts Elevator
Lifts approximately 20.5 kg fixtures between conveyor tiers, taking advantage of the shorter JIS body to fit within tight vertical transfer machine enclosures.
Automated Gate Actuator
Extends heavy access doors on CNC machining centres, where the fixed TPU bumper pads reliably absorb the impact at the end of the 450 mm travel.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X450CA the Right Cylinder?
When sizing this 32 mm bore unit against the family, dropping down to the MF25 reduces the 0.5 MPa push capacity to 245.3 N, whereas stepping up to the MF40 increases it to 628.3 N. At a 450 mm extension, the Ø12 mm rod is highly susceptible to bending forces if subjected to lateral loads, so ensure the load moves along a strictly linear guide. The CA rear pivot mount is ideal for applications requiring angular alignment compensation during the 450 mm travel.
Note that standard double-acting operation will not hold a load in place if air pressure drops or the directional valve centres; the piston will drift, as the fixed TPU bumpers only decelerate the stroke end rather than locking it. To suspend a vertical load safely, incorporate an external pilot-operated check valve or a dedicated rod lock. Furthermore, because this configuration omits the -S magnet, adding position feedback requires switching to a magnet-equipped variant to accept CMSG or DMSG switches.
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 MF32X450CA FAQ
This 32 mm bore cylinder features a 1/4" air port and an M10x1.25 male rod thread. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum force of 82 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing; additionally, its JIS-standard riveted body is shorter than an ISO 6432 cylinder, and the CA rear cover provides a pivot mount.
