Airtac MF32-40 Stainless Steel Mini Cylinder MF40X50SCA
The AirTAC Airtac MF32-40 Stainless Steel Mini Cylinder MF40X50SCA is a genuine double acting JIS-standard round-body mini air cylinder with a Ø40mm 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 MF40X50SCA
Delivering 628.3 N of push force at 0.5 MPa, the AirTAC MF40X50SCA is a 40 mm bore double-acting JIS-standard round-body mini cylinder. Because its riveted rolling-packed structure is physically shorter than an ISO 6432 cylinder of the same bore and stroke, it saves valuable mounting length in tight machinery. 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.
This specific SKU includes a built-in magnet for position sensing and a CA rear pivot cover. Fixed TPU bumper pads and a front-cover anti-impact pad soften stroke-end impact by decelerating the motion. For practical sizing, plan for about 377 N of real work at 0.5 MPa, which means it can safely lift a 32 kg part vertically with a 2:1 safety margin.

Where the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X50SCA Is Used
Clamp Actuation
Provides 628.3 N of push force at 0.5 MPa to secure heavy cast metal parts during CNC milling operations.
Pneumatic Pressing
Drives a short 50 mm stroke to press bearings into housings, utilizing the fixed TPU bumpers to absorb end-of-stroke impact.
Diverter Gate
Uses the CA rear pivot mount to swing a heavy routing gate on a packaging line, handling loads up to 32 kg safely.
Is the Airtac MF32-40 Stainless Steel Mini Cylinder MF40X50SCA the Right Cylinder?
When sizing this 40 mm bore, stepping down to the MF32 yields 402.2 N of push force at 0.5 MPa, while the MF40 is the largest available option in the series at 628.3 N. Choose the 40 mm bore when your load demands that extra thrust. The included CA pivot mount is ideal for articulating loads, and you can pair this -S magnet version directly with CMSG, DMSG, or EMSG switches for end-of-stroke confirmation.
Remember that a standard double-acting cylinder drifts if air pressure drops or the valve is centred; the TPU bumpers only soften the end of travel and do not function as a braking lock. To suspend a load safely mid-stroke, integrate an external pilot-operated check valve or a dedicated rod lock. Furthermore, on this 50 mm stroke, keep the load guided to prevent side-loading and premature rod seal wear.
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 MF40X50SCA FAQ
This 40 mm bore double-acting cylinder features a 1/4" air port and an M14x1.5 male rod thread. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum force of 128.1 kgf at 1.0 MPa.
No, the MF is a JIS-standard round-body cylinder, not an ISO 6432 unit, though its riveted stainless steel body is deliberately shorter than an ISO equivalent to save space. Because this SKU includes the -S magnet, you can mount CMSG, DMSG, or EMSG switches directly to the groove for position detection.
