Airtac MF32-40 Stainless Steel Mini Cylinder MF40X30SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X30SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm bore and 30mm 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 MF40X30SCM
Generating 628.3 N of push force at 0.5 MPa, the AirTAC MF40X30SCM is a robust 40 mm bore double-acting mini cylinder. Its JIS-standard round-body construction pairs a SUS304 stainless steel barrel with riveted aluminium covers, giving you a footprint that is physically shorter than an ISO 6432 cylinder for the same 30 mm stroke. This compact profile helps engineers squeeze actuators into densely packed machinery. The built-in piston magnet (-S) supports CMSG, DMSG and EMSG switches for position sensing.
The riveted rolling-packed structure shrugs off mild corrosion and washdown environments. Inside, a two-way oil-retaining seal keeps the piston lubricated for a long service life, while fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impacts. For practical sizing, plan for roughly 377 N of real work at 0.5 MPa, which translates to lifting about 32 kg vertically with a 2:1 safety margin. The 1/4" port and M14x1.5 male rod thread handle the necessary air volume for high-force cycles.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X30SCM Is Used
Short-Stroke Stamping
Ideal for driving small press dies or marking assemblies in metal fabrication, utilising the 628.3 N push force across a rapid 30 mm travel.
Heavy Diverter Gate
Actuates robust routing flaps on packaging lines, where the 40 mm bore provides enough thrust to shift heavy cartons without stalling.
Pallet Stopper Block
Functions as a high-strength physical stop for loaded pallets on roller conveyors, safely absorbing impact with its built-in TPU bumper pads.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X30SCM the Right Cylinder?
When sizing this 40 mm bore, compare your actual load against the 628.3 N push force at 0.5 MPa. If your application is lighter, stepping down to the 32 mm bore drops the output to 402.2 N, saving air and space; since 40 mm is the largest available MF bore, heavier loads require a different cylinder family. The CM round-end back cover on this unit provides a specific pivot mounting interface, so ensure your clevis matches accordingly. You can also utilise LB foot, FA flange, SDB pivot or TC trunnion brackets. Because this is a short 30 mm stroke, side-load and rod-bending risks are minimal, but always guide the load rigidly. Remember that a standard cylinder drifts when air is lost or a valve is centred, so install an external rod lock or pilot check valve if you need to hold a suspended weight. The fixed TPU bumpers only decelerate the stroke end and cannot act as a mechanical brake.
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 MF40X30SCM FAQ
This 40 mm bore double-acting cylinder uses a 1/4" air port and an M14x1.5 male rod thread. At 0.5 MPa it pushes with 628.3 N and pulls with 527.8 N. At 0.7 MPa the push increases to 879.6 N and the pull to 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
Yes, the -S suffix denotes a built-in piston magnet, allowing you to mount CMSG, DMSG or EMSG reed and electronic switches directly onto the barrel. The CM designation indicates a round-end back cover, designed for pivot or clevis mounting to accommodate angular movement during the stroke.
