Airtac MTF Mini Cylinder MTF25X25SCM
The AirTAC Airtac MTF Mini Cylinder MTF25X25SCM is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 25mm 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 MTF25X25SCM
Designed for spring-open, air-close tasks, this JIS-standard round-body mini cylinder relies on an internal spring to push the 10 mm rod out, using compressed air through its 1/8" port to retract the load. The SUS304 stainless barrel and riveted aluminium covers yield a shorter envelope than an ISO 6432 unit, saving valuable machine space while resisting mild washdown. As a single-acting pull type, it safely fails to the extended position if air pressure drops.
Delivering a net pull of 153.6 N at 0.5 MPa (236 N at 0.7 MPa) after overcoming the spring, it fits light tensioning and retraction jobs perfectly. For a stable vertical lift, expect a safe working load of about 92 N, or roughly 7.8 kg with a 2:1 margin. The included -S magnet supports CMSG, DMSG, and EMSG position sensing, while the CM round-end back cover and fixed TPU bumper pads complete the assembly.

Where the Airtac MTF Mini Cylinder MTF25X25SCM Is Used
Tensioning Systems
Maintains steady pulling tension on web materials or belts, using the 153.6 N retraction force to pull slack, while the spring ensures the line stays tensioned if air is removed.
Fail-Safe Gate Opening
Holds a guard door open with air pressure and relies on the internal spring to snap the rod back out, ensuring the barrier physically extends into the safe state upon pneumatic failure.
Vertical Load Retraction
Pulls light fixtures or tooling up and out of the way, safely handling vertical loads around 7.8 kg with a 2:1 margin before dropping them to the extended rest position on shutdown.
Is the Airtac MTF Mini Cylinder MTF25X25SCM the Right Cylinder?
When sizing this 25 mm bore, verify if the 153.6 N pull at 0.5 MPa meets your retract requirement; if the load is lighter, step down to the MTF20 which provides 93.4 N, or if more force is needed, move up to the MTF32 rated at 266.8 N. Remember that a minimum of 0.2 MPa operating pressure is required to overcome the internal spring. The built-in -S magnet allows seamless integration with CMSG, DMSG, or EMSG switches for end-of-stroke confirmation.
This single-acting pull configuration is optimal for mechanisms that must return to an extended, fail-safe state during a power or air loss event. You can mount it using LB foot, FA flange, SDB pivot, or TC trunnion brackets to suit your frame. Note that it relies on fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable air cushion.
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 MTF25X25SCM 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 limit of 1.0 MPa.
The internal spring constantly extends the rod, meaning the cylinder fails to the extended position if air pressure is lost; it cannot hold a mid-stroke load. Because this model includes the -S magnet, it fully supports CMSG, DMSG, and EMSG electronic or reed switches for position detection.
