Airtac MTF Mini Cylinder MTF25X15SCM
The AirTAC Airtac MTF Mini Cylinder MTF25X15SCM is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 15mm stroke, 1/8" 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 MTF25X15SCM
Delivering a net pull of 153.6 N at 0.5 MPa, this JIS-standard round-body mini cylinder uses a single-acting pull mechanism where an internal spring holds the rod extended and air retracts it. The SUS304 stainless steel barrel and riveted aluminium covers form a compact assembly that is physically shorter than an equivalent ISO 6432 unit, saving valuable mounting length while resisting mild washdown corrosion. Equipped with a CM round-end rear cover, it breathes freely while cycling.
The bore is 25 mm with a 10 mm rod, a male M10x1.25 thread, and a 1/8" port. Because the spring constantly pushes outward, the cylinder fails safely to the extended position on air loss, making it ideal for spring-open and air-close tasks. The quoted pull force is already net of the spring, yielding a safe working load of about 92 N or a vertical lift capacity of roughly 7.8 kg with a 2:1 margin. This specific SKU includes the -S magnet for position sensing and uses fixed TPU bumper pads for end-of-stroke deceleration.

Where the Airtac MTF Mini Cylinder MTF25X15SCM Is Used
Tensioning Mechanisms
Uses the 153.6 N pull force to maintain strap or wire tension, releasing the load only when compressed air retracts the rod.
Fail-Safe-Open Valves
Holds a valve open via spring pressure; air retracts the rod to close it, ensuring the system defaults to open on air loss.
Clamp Release
Pulls back a holding pin or clamp to free parts, relying on the spring to re-engage the clamp when air is removed.
Is the Airtac MTF Mini Cylinder MTF25X15SCM the Right Cylinder?
When sizing this unit, compare it both ways: the smaller MTF20 bore provides 93.4 N of pull at 0.5 MPa, while the larger MTF32 offers 266.8 N. This 25 mm bore fits neatly in the middle for applications needing roughly 153.6 N of retraction force at 0.5 MPa. A minimum operating pressure of 0.2 MPa is required to overcome the internal spring and pull the rod inward.
The single-acting pull design is optimal for tensioning, clamping releases, or fail-safe-open mechanisms where the load must return to the extended position if air pressure drops. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion brackets. Because this model carries the -S suffix, it accepts CMSG, DMSG, or EMSG sensors for precise position feedback.
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 0.2 – 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 MTF25X15SCM FAQ
This single-acting cylinder provides a net pull force of 153.6 N at 0.5 MPa and 236 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the return spring, with a maximum pressure of 1.0 MPa and a proof pressure of 1.5 MPa.
The internal spring constantly extends the rod, meaning air is only used to retract it and the cylinder fails to the extended position on air loss. This model includes the -S magnet for use with CMSG, DMSG, or EMSG sensors, and features a CM round-end rear cover.
