Airtac MF32-40 Stainless Steel Mini Cylinder MF32X50CM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X50CM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 50mm 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 MF32X50CM
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MF32X50CM is a JIS-standard round-body mini cylinder built for tight machinery layouts. Its SUS304 stainless barrel and riveted aluminium covers resist mild corrosion and washdown, while the internal two-way seal retains an oil film for extended mechanical life. Because this 32 mm bore uses a 1/4" port and a compact riveted structure, the overall body length is physically shorter than a comparable ISO 6432 cylinder, giving you a tangible packaging advantage in dense fixtures.
This double-acting actuator uses fixed TPU bumper pads and a front-cover anti-impact pad to soften stroke-end impacts, operating at speeds from 30 to 800 mm/s. For practical sizing, plan for a safe working load of roughly 241 N, which translates to lifting a 20.5 kg mass vertically with a 2:1 safety margin. Note that this specific SKU lacks a magnet, so it cannot host CMSG, DMSG, or EMSG position switches without upgrading to the -S variant.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X50CM Is Used
Package Diverting Arm
Extends a 50 mm stroke to push small totes at a sorting junction, utilising the 402.2 N push force to overcome carton friction without stalling.
Clamp Actuation
Secures mild steel plates in a machining cell, where the SUS304 barrel withstands occasional cutting fluid splash during automated milling.
Pallet Stopper Gate
Deploys a rigid stop block to halt incoming pallets on a gravity roller track, relying on the fixed TPU pads to absorb the kinetic impact.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X50CM the Right Cylinder?
When sizing this 32 mm bore, compare your actual load against the 402.2 N push force at 0.5 MPa. If your application is lighter, stepping down to the MF25 yields 245.3 N and saves physical space; if you need more thrust, the MF40 provides 628.3 N. This model features a CM round-end back cover, so ensure your mounting clevis accommodates that profile, or explore alternative LB foot, FA flange, or TC trunnion brackets. For high-cycle automation requiring precise end-position feedback, remember this non-magnetic version cannot accept sensors.
With a 50 mm stroke, side-load risks are minimal, but always align the rod to prevent premature seal wear. Furthermore, standard double-acting cylinders drift when air supply is lost or the valve is centred—the fixed bumpers only decelerate the stroke end and act as no brake. If your process demands strict position holding under load, integrate an external pilot check valve or a dedicated rod lock.
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 MF32X50CM FAQ
This 32 mm bore double-acting cylinder features a 1/4" 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 of 82 kgf at 1.0 MPa.
No, this specific SKU does not include a piston magnet, so CMSG, DMSG, or EMSG switches cannot be used. You would need the -S variant for sensing. It features a CM round-end back cover and is shorter than an ISO 6432 cylinder for the same stroke.
