The AirTAC Airtac MTF Mini Cylinder MTF32X60SCM is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø32mm bore and 60mm 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.
Generating 266.8 N of pull at 0.5 MPa, this 32 mm bore AirTAC MTF32X60SCM is a JIS-standard round-body mini cylinder built for single-acting tension applications. The internal spring constantly pushes the rod out, while supplying air to the 1/4 inch port retracts it. Because the spring holds the piston extended, any loss of air pressure automatically drives the rod back out, providing a fail-safe open mechanism for gates, vents, and clamps.
The SUS304 stainless steel barrel shrugs off mild corrosion and washdown environments, and the riveted aluminium covers yield a shorter overall body than an equivalent ISO 6432 unit. For sizing, the quoted force is already net of the spring, requiring at least 0.2 MPa to overcome it. Factoring a 2:1 safety margin, this bore pulls or holds roughly 13.6 kg vertically, with a safe working load around 160 N. The CM round-end back cover and included -S magnet for CMSG/DMSG/EMSG switches round out the build.

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 spring to hold a ventilation louver open, using the 266.8 N pull to snap it shut only when pressurized air is applied.
Maintains steady belt or web tension via the extended spring, retracting to release the load with its 13.6 kg effective pull capacity.
Locks a diverter or isolation gate in the extended rest position, pulling it closed pneumatically while surviving washdown via the SUS304 barrel.
When sizing this 32 mm bore, compare it directly against the adjacent bores: a smaller MTF25 yields 153.6 N at 0.5 MPa, while stepping up to the MTF40 provides 434.8 N. This MTF32X60SCM fits squarely in the middle, offering 266.8 N at 0.5 MPa (405 N at 0.7 MPa). Choose this single-acting pull configuration when a mechanism must fail to the extended position, such as spring-open/air-close doors or tensioning systems. Ensure your air supply stays between 0.2 and 1.0 MPa, as 0.2 MPa is the minimum floor required to beat the spring. The CM rear cover and standard mounting options like LB foot or TC trunnion simplify installation.
Quick checklist
The 32 mm bore generates 266.8 N of pull at 0.5 MPa and 405 N at 0.7 MPa. These figures are net of the spring. It requires an operating pressure between 0.2 and 1.0 MPa, with 0.2 MPa being the minimum floor needed to overcome the return spring and retract the rod via the 1/4 inch port.
The spring constantly extends the rod, meaning the cylinder fails to the extended position on air loss rather than holding a mid-stroke load. The -S option includes a piston magnet for CMSG, DMSG, or EMSG position sensing. It uses fixed TPU bumper pads for end-of-stroke deceleration, not an adjustable air cushion.
