Airtac MF32-40 Stainless Steel Mini Cylinder MF32X40SCM
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF32X40SCM is a genuine double acting JIS-standard round-body mini air cylinder with a Ø32mm bore and 40mm 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 MF32X40SCM
Delivering 402.2 N of push force at 0.5 MPa, this double-acting AirTAC MF32X40SCM is a JIS-standard round-body mini cylinder built for tight machinery. Because its riveted rolling-packed structure is physically shorter than a comparable ISO 6432 unit of the same 32 mm bore and 40 mm stroke, it saves valuable mounting length in compact fixtures. The SUS304 stainless steel barrel and aluminium covers resist mild corrosion and washdown, while the piston's two-way seal retains an oil film for long service life.
Fitted with a 1/4 inch port and an M10x1.25 male rod thread, the unit uses fixed TPU bumper pads alongside a front-cover anti-impact pad to soften stroke-end impact. The -S suffix denotes a built-in piston magnet for CMSG, DMSG, or EMSG switches, and the CM suffix specifies a round-end rear cover. Plan for roughly 241 N of actual work at 0.5 MPa, which means it can safely lift about 20.5 kg vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X40SCM Is Used
Clamp Actuation
Drives 241 N of gripping force on a CNC machining fixture, securely holding aluminium housings during milling.
Package Diverting
Extends a 40 mm stroke to push cardboard cartons weighing up to 20.5 kg onto a secondary packaging line.
Component Insertion
Presses small bearings into housings on an automated assembly carousel using its 402.2 N thrust rating.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF32X40SCM the Right Cylinder?
When sizing this 32 mm bore, the smaller MF25 yields 245.3 N and the larger MF40 yields 628.3 N at 0.5 MPa, giving clear stepping stones for adjusting your force budget. For this specific 40 mm stroke, side-load and rod-bending stress are minimal, but always align the load to prevent premature seal wear. The included magnet allows seamless position detection.
Remember that a standard cylinder drifts if air pressure drops or the valve is centred; the TPU pads only decelerate the stroke end and act as neither a brake nor a lock. To suspend a load safely mid-stroke, integrate an external pilot-operated check valve or a dedicated rod lock. You can mount this unit using LB foot brackets, FA flanges, SDB pivot blocks, or TC trunnions.
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 MF32X40SCM FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N. At 0.7 MPa it pushes 563 N and pulls 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. This 32 mm bore model uses a 1/4 inch air port and an M10x1.25 male rod thread.
Yes, the -S suffix means a magnet is built into the piston, allowing you to mount CMSG, DMSG, or EMSG reed or electronic switches directly onto the SUS304 stainless barrel. The CM designation indicates a round-end rear cover, which is compatible with SDB pivot-block mounting for angular movement.
