Airtac MF32-40 Stainless Steel Mini Cylinder MF32X250SCMLB
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X250SCMLB is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 250mm 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 MF32X250SCMLB
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 1/4" port feeds a two-way oil-retaining piston seal, and fixed TPU bumper pads absorb the stroke-end impact alongside a front-cover anti-impact pad. Because the MF body is shorter than an ISO 6432 cylinder for the same 32 mm bore and 250 mm stroke, it trims valuable mounting length from tight machine layouts.
For practical sizing, plan for about 241 N of real work at 0.5 MPa, which lets you lift a 20.5 kg part vertically with a safe 2:1 margin. The -S suffix equips the piston with a magnet for CMSG, DMSG, or EMSG switches, while the CM round-end back cover and LB foot bracket expand your mounting options.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X250SCMLB Is Used
Carton Diverter Arm
Swings a routing gate on a packaging line using 402.2 N of push force to redirect heavy corrugated boxes at high speed.
Vertical Parts Lift
Raises 20.5 kg fixtures between conveyor tiers with a safe 2:1 margin, capitalizing on the 250 mm stroke and compact JIS body.
Clamp Actuation
Secures aluminium extrusions in a machining cell, using the built-in magnet to confirm clamp position via a DMSG sensor.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X250SCMLB the Right Cylinder?
When sizing this 32 mm bore, stepping down to the MF25 drops the 0.5 MPa push force to 245.3 N, whereas moving up to the MF40 raises it to 628.3 N. The 250 mm stroke is well within the 500 mm standard limit, but at this extension you must carefully manage side loads to prevent rod bending and premature seal wear.
The LB foot bracket fixes the body, while the CM round-end back cover accommodates rear pivot mounting. Remember that a plain double-acting cylinder drifts if air pressure drops or the valve centres; the TPU bumpers only soften the end of stroke rather than locking the load. Use an external rod lock or pilot check valve if you need to hold a vertical position securely.
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 MF32X250SCMLB FAQ
This 32 mm bore 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.
It is a JIS-standard round-body cylinder with a SUS304 stainless barrel and riveted rolling-packed covers, making the overall body shorter than an ISO 6432 unit for the same stroke. It includes a CM round-end back cover, an LB foot bracket, and fixed TPU bumper pads that decelerate the piston rather than providing adjustable air cushioning.
