Airtac MF32-40 Stainless Steel Mini Cylinder MF32X90CA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X90CA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 90mm 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 MF32X90CA
Delivering 402.2 N of push force at 0.5 MPa, this double-acting JIS-standard round-body mini cylinder is built around a SUS304 stainless barrel with riveted aluminium covers. The riveted rolling-packed structure shrinks the body profile, making it physically shorter than an ISO 6432 cylinder of the identical bore and stroke. Inside, a heterogeneous two-way seal retains an oil film for extended lifespan, while fixed TPU bumper pads and a front-cover anti-impact pad absorb stroke-end shock.
For practical actuation tasks, plan your mechanism around a safe working load of roughly 241 N, which represents about sixty percent of the 0.5 MPa push rating. If you are lifting a mass vertically, this translates to hoisting around 20.5 kg safely with a two-to-one margin. The 1/4 inch port supplies ample airflow to drive the 12 mm piston rod, and the included CA back cover provides a rear pivot point for angular movement.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X90CA Is Used
Articulated Gripper Arms
Uses the CA pivot back cover to actuate a swinging robotic gripper, moving workpieces with a reliable 402.2 N push force at 0.5 MPa.
Package Diverter Gates
Leverages the 90 mm stroke to push sorting flaps on a packaging line, where the shorter JIS body preserves valuable conveyor clearance.
Vertical Material Lifts
Hoists small pallets or bins weighing up to 20.5 kg, relying on the SUS304 stainless barrel to withstand mildly humid or washdown environments.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X90CA the Right Cylinder?
When sizing this 32 mm bore against neighbouring options, the MF25 provides 245.3 N at 0.5 MPa if your load is lighter, while stepping up to the MF40 yields 628.3 N for heavier demands. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches; you must select an -S variant if your application requires electronic stroke sensing. The built-in CA rear pivot mount suits articulated linkages, and you can adapt the front end using LB foot, FA flange, or TC trunnion hardware.
Remember that the fixed TPU bumpers only decelerate the piston near the stroke end; they do not function as a braking mechanism. If air pressure drops or the control valve is centred, the rod will drift and drop the load. To prevent unintended descent, integrate an external pilot-operated check valve or a dedicated rod lock into your pneumatic 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 MF32X90CA FAQ
This 32 mm bore cylinder features a 1/4 inch air port and an M10x1.25 male rod thread. The double-acting thrust outputs are 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.
No, this specific SKU does not include a piston magnet, so it cannot accept CMSG, DMSG, or EMSG magnetic switches. You would need the MF32X90CA-S variant for electronic position sensing. The unit uses fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable air cushion.
