Airtac MTF Mini Cylinder MTF40X75SCM
The AirTAC Airtac MTF Mini Cylinder MTF40X75SCM is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø40mm bore and 75mm 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 MTF Mini Cylinder MTF40X75SCM
Delivering a robust 434.8 N of pull force at 0.5 MPa, this AirTAC MTF40X75SCM mini cylinder is engineered for single-acting tension and fail-safe-open tasks. The internal spring actively holds the rod extended, while applying air to the 1/4 inch port retracts it. Because the spring constantly pushes outward, any loss of pneumatic pressure automatically drives the rod back out to its extended rest state. The quoted pull figures are already net of the spring resistance, meaning the full force is available for your workload.
Built as a JIS-standard round-body unit, the SUS304 stainless steel barrel and riveted aluminium covers provide excellent resistance to mild corrosion and washdown environments. For the same 40 mm bore and 75 mm stroke, this riveted construction is noticeably shorter than a comparable ISO 6432 cylinder, saving valuable machine space without conforming to ISO dimensions. This specific SKU includes a built-in piston magnet for position sensing and features a CM round-end back cover. End-of-stroke deceleration is handled by fixed TPU bumper pads rather than an adjustable air cushion. Factoring a 2:1 safety margin against the 0.5 MPa rating, you can reliably lift or hold approximately 22.2 kg vertically.

Where the Airtac MTF Mini Cylinder MTF40X75SCM Is Used
Heavy-Duty Tensioning
Pulls and maintains strong cable or web tension with 434.8 N of force at 0.5 MPa, releasing the load instantly when air is applied to the 1/4 inch port.
Fail-Safe Door Opening
Keeps heavy access doors sprung open during pneumatic loss, using compressed air only to pull the 16 mm rod and close the barrier securely.
Vertical Load Retraction
Lifts and holds roughly 22.2 kg against gravity using a 2:1 safety margin, relying on the spring to push the payload back out when air pressure drops.
Is the Airtac MTF Mini Cylinder MTF40X75SCM the Right Cylinder?
Choose this 40 mm bore if your mechanism requires a spring-open, air-close action with substantial pulling power. It yields 434.8 N of pull at 0.5 MPa and 645.8 N at 0.7 MPa. If your load is lighter, step down to the MTF32 bore, which provides 266.8 N at 0.5 MPa; as 40 mm is the largest bore in the MTF family, you cannot size up further within this series. Ensure your air supply provides at least the 0.2 MPa floor required to overcome the internal spring before any retraction occurs.
The -S suffix on this model means a magnet is installed, allowing you to mount CMSG, DMSG, or EMSG electronic or reed switches directly onto the stainless barrel for end-of-stroke confirmation. Mounting flexibility is extensive: pair the CM back cover with LB foot brackets, FA flanges, SDB pivot blocks, or TC trunnions to suit your frame layout.
Quick checklist

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.2 – 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 MTF Mini Cylinder MTF40X75SCM FAQ
This 40 mm bore cylinder generates 434.8 N of pull force at 0.5 MPa and 645.8 N at 0.7 MPa. These figures are net of the internal spring. It requires a minimum operating pressure of 0.2 MPa to overcome the spring and retract the rod, with a maximum pressure limit of 1.0 MPa and a proof pressure of 1.5 MPa.
The spring constantly extends the 16 mm rod, and air retracts it. On air loss, it fails safely to the extended position; it cannot hold an arbitrary mid-stroke load. For mid-stroke holding, use a double-acting MF cylinder with an external rod lock. This unit also features a SUS304 stainless barrel, fixed TPU bumpers, and a magnet for CMSG/DMSG/EMSG sensors.
