Airtac MTF Mini Cylinder MTF25X100CM
The AirTAC Airtac MTF Mini Cylinder MTF25X100CM is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 100mm 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 MTF25X100CM
Delivering a net pull force of 153.6 N at 0.5 MPa, this JIS-standard round-body mini cylinder is built for single-acting pull operations. The MTF25X100CM uses an internal spring to push the 10 mm rod out to its extended rest position, while supplying air to the 1/8 inch port retracts it. If air pressure drops, the spring automatically drives the rod back out, creating a fail-safe-to-extended action ideal for closing or tensioning tasks.
The SUS304 stainless steel barrel and riveted aluminium covers provide reliable resistance to mild corrosion and washdown environments. Because this specific SKU lacks the -S magnet option, it cannot host CMSG, DMSG, or EMSG sensors. For sizing reference, the 153.6 N pull at 0.5 MPa translates to a safe working load of roughly 92 N, or a vertical lift capacity of about 7.8 kg when applying a 2:1 safety margin.

Where the Airtac MTF Mini Cylinder MTF25X100CM Is Used
Spring-Return Tensioning
Uses the 153.6 N pull force to draw back a tensioned strap or cable, relying on the spring to maintain the extended rest position when air is removed.
Fail-Safe Door Opening
Air retracts the rod to pull a door closed, but upon air loss the internal spring forces the rod out, automatically opening the door for safety egress.
Lightweight Clamping Release
Holds a 7.8 kg load against a stop using air pressure, releasing the clamp instantly when the 1/8 inch port is vented to let the spring extend.
Is the Airtac MTF Mini Cylinder MTF25X100CM the Right Cylinder?
When sizing this 25 mm bore model, compare its 153.6 N pull at 0.5 MPa against the smaller MTF20, which yields 93.4 N, or the larger MTF32, which provides 266.8 N. This cylinder requires a minimum of 0.2 MPa operating pressure to overcome the internal spring, with a maximum limit of 1.0 MPa. It features fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable air cushion.
This configuration includes a CM round-end rear cover and supports LB foot, FA flange, SDB pivot, and TC trunnion mounting. Keep in mind that without the -S magnet, position sensing is not possible. The JIS-standard round-body design is also notably shorter than a comparable ISO 6432 cylinder, saving valuable mounting length.
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 MTF25X100CM FAQ
This single-acting pull 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.
No, this specific SKU does not include a magnet, so it cannot support CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. Additionally, the spring always extends the rod to its rest position on air loss and will not hold a mid-stroke load.
