Airtac MF32-40 Stainless Steel Mini Cylinder MF32X50SUTC
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X50SUTC 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 MF32X50SUTC
Delivering 402.2 N of push force at 0.5 MPa, the AirTAC MF32X50SUTC is a JIS-standard round-body mini cylinder built for tight machinery layouts. Its SUS304 stainless barrel and riveted aluminium covers shrug off mild washdown, while the internal two-way seal retains an oil film for long service life. Because this 32 mm bore body is physically shorter than a comparable ISO 6432 cylinder, it saves valuable mounting length without sacrificing the 50 mm stroke.
This double-acting actuator uses fixed TPU bumper pads and a front-cover anti-impact pad to soften stroke-end impact rather than relying on an adjustable cushion. The built-in piston magnet (-S) supports CMSG, DMSG, and EMSG position switches. For real-world sizing, plan for a safe working load of roughly 241 N, which translates to lifting about 20.5 kg vertically with a 2:1 safety margin. Air connects via a 1/4" port, and the rear features a U flat-end cover paired with a TC trunnion mount.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X50SUTC Is Used
Component Clamping
Secures aluminium machining blanks inside CNC fixtures, using the 402.2 N push force to hold parts rigidly against the spindle cutting forces.
Package Diverting
Actuates a routing gate on a packaging line, where the compact JIS body length leaves room for adjacent drive rollers and the TC trunnion absorbs pivot stress.
Vertical Part Lifting
Raises lightweight plastic tote bins between conveyor tiers, safely lifting loads around 20.5 kg when applying a 2:1 vertical lift safety margin.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X50SUTC the Right Cylinder?
When sizing this 32 mm bore, compare it directly with its neighbours: the MF25 provides 245.3 N of push at 0.5 MPa, while the MF40 steps up to 628.3 N. If your fixture demands exact position holding on air loss, remember that a standard cylinder drifts when the valve centres—the TPU pads only decelerate the end of travel and act as neither a brake nor a lock. You must add an external rod lock or a pilot-operated check valve to secure a suspended load. The included TC trunnion mount pairs with the U flat-end back cover to handle pivoting articulation smoothly.
With a 50 mm stroke, side-load risks are minimal, but always align the rod to prevent premature seal wear. If your cycle speed pushes the 30-800 mm/s limit and the fixed bumpers cannot absorb the kinetic energy, consider the MFC variant for its adjustable air cushion.
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 MF32X50SUTC FAQ
This 32 mm bore cylinder features a 1/4" air port and an M10x1.25 male rod thread. At 0.5 MPa it pushes with 402.2 N and pulls with 345.6 N. At 0.7 MPa the push increases to 563 N and the pull to 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
The JIS-standard round-body design is physically shorter than an ISO 6432 cylinder for the same 32 mm bore and 50 mm stroke, saving mounting length. It uses a SUS304 stainless barrel with riveted aluminium covers. This specific configuration includes a U flat-end back cover and a TC trunnion mount, and the -S magnet allows CMSG, DMSG, or EMSG sensors to track position.
