Airtac MTF Mini Cylinder MTF32X150SCM
The AirTAC Airtac MTF Mini Cylinder MTF32X150SCM is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø32mm bore and 150mm 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.

About the Airtac MTF Mini Cylinder MTF32X150SCM
Delivering 266.8 N of pull force at 0.5 MPa (405 N at 0.7 MPa), this JIS-standard round-body mini cylinder is built for single-acting pull operation. The internal spring actively extends the 12 mm rod to its rest state, while supplying air to the 1/4" port retracts it. Because the spring constantly pushes outward, the unit fails to the extended position upon air loss, making it perfectly suited for spring-open and air-close mechanisms.
The SUS304 stainless steel barrel and riveted aluminium covers yield a shorter overall envelope than an equivalent ISO 6432 unit while resisting mild washdown corrosion. End-of-stroke impact is managed by fixed TPU bumper pads rather than an adjustable cushion. For a 2:1 safety margin, the effective vertical lift capacity is roughly 13.6 kg, and the base SKU lacks a piston magnet, so position sensing is unavailable on this specific configuration.

Where the Airtac MTF Mini Cylinder MTF32X150SCM Is Used
Tensioning Mechanisms
Uses the 266.8 N pull force to draw back and maintain tension on belts or web materials, releasing the load safely to the extended position if air pressure drops.
Fail-Safe Open Valves
Holds a valve open via spring pressure and pulls it closed on air command, ensuring the pipeline defaults to an open state during a pneumatic power loss.
Retracting Conveyor Stops
Pulls a physical stop gate out of the product flow path when actuated, allowing the internal spring to push the gate back into place to halt items when air is removed.
Is the Airtac MTF Mini Cylinder MTF32X150SCM the Right Cylinder?
When sizing this 32 mm bore, compare its 266.8 N @0.5 MPa pull force against the adjacent options: step down to an MTF25 for 153.6 N, or step up to an MTF40 for 434.8 N. You must supply at least 0.2 MPa of air pressure to overcome the internal spring and successfully retract the rod. This model features the CM round-end rear cover and a 150 mm stroke, utilizing fixed TPU bumpers for end-of-stroke deceleration across its 50-800 mm/s speed range. To mount the cylinder, select from LB foot, FA flange, SDB pivot-block, or TC trunnion hardware. Note that because this configuration lacks the -S magnet suffix, it cannot support CMSG, DMSG, or EMSG sensors.
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 MTF32X150SCM FAQ
This 32 mm bore cylinder provides a net pull force of 266.8 N at 0.5 MPa and 405 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the return spring and retract the rod.
The spring constantly extends the rod, meaning the cylinder fails to the extended position on air loss and cannot hold a mid-stroke load. It features a CM round-end rear cover, fixed TPU bumper pads, and because this specific SKU lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG sensors.
