The AirTAC Airtac MTF Mini Cylinder MTF25X10SCM is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø25mm bore and 10mm 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.
Generating 153.6 N of pull at 0.5 MPa, this AirTAC MTF25X10SCM mini cylinder is built for single-acting tension and fail-safe-open tasks. It features a JIS-standard round body with a SUS304 stainless barrel and riveted aluminium covers, giving you a shorter mounting envelope than an ISO 6432 unit of the same footprint. The internal spring holds the rod extended at rest, while applying air to the 1/8 inch port retracts it.
Because the spring constantly pushes outward, the quoted pull force is already net of that spring resistance, and a minimum of 0.2 MPa is required to overcome it. For sizing, this yields a safe working load of about 92 N, or roughly 7.8 kg of vertical lift with a 2:1 margin. The 10 mm stroke is capped by fixed TPU bumper pads, and the built-in magnet (-S) supports CMSG, DMSG or EMSG sensors, while the CM round-end back cover suits compact pivot or surface mounting.

Single-acting pull: the spring extends the rod; air retracts it. Forces already net the spring; minimum working pressure is 0.2 MPa.

MF-family variants: MF / MFC (double acting ±cushion), MSF / MTF (single acting push / pull), MFD / MFCD (double rod ±cushion), MFJ / MFCJ (adjustable stroke ±cushion). Back covers CA / U / CM. Mounting LB / FA / SDB / TC.
Uses the 153.6 N pull force to draw back a tension belt or cable against a constant spring release.
Holds a guard open via air; the spring automatically drives the rod out to secure the opening upon pressure loss.
Pulls a 10 mm stroke pin out of the way, allowing the internal spring to mechanically extend and clear the part.
If 93.4 N from the MTF20 is too light, this bore steps up to 153.6 N at 0.5 MPa; should you need substantially more clamping power, the MTF32 provides 266.8 N. Choose this single-acting pull type when a mechanism must spring-open and air-close, such as a tensioning jaw that must mechanically fail to the extended position on air loss. Ensure your supply meets the 0.2 MPa floor to retract the rod. The -S magnet enables position sensing, and the CM back cover provides a neat rear mounting face for tight fixtures.
Quick checklist
It delivers a net pull force of 153.6 N at 0.5 MPa and 236 N at 0.7 MPa. A minimum of 0.2 MPa is required to overcome the internal spring and retract the rod.
The spring extends the rod to its resting position, so on air loss it fails to the extended state. The -S option includes a piston magnet for CMSG, DMSG or EMSG sensors, and the CM round-end back cover aids compact rear mounting.
