Airtac MTF Mini Cylinder MTF32X20CM
The AirTAC Airtac MTF Mini Cylinder MTF32X20CM is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø32mm bore and 20mm 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 MTF32X20CM
Delivering 266.8 N of net pull at 0.5 MPa, this 32 mm bore mini cylinder is engineered for single-acting tension and fail-safe-open tasks. The internal spring constantly pushes the rod out to its extended rest position, while supplying air to the 1/4 inch port retracts it. Because the spring provides the extension force, the cylinder automatically drives to the extended position if air pressure drops below the 0.2 MPa floor or is lost entirely.
Built as a JIS-standard round-body unit, the SUS304 stainless steel barrel and riveted aluminium covers yield a shorter mounting envelope than an equivalent ISO 6432 cylinder while resisting mild washdown corrosion. This specific SKU lacks a magnet and cannot host position sensors; adding the -S option enables CMSG, DMSG, or EMSG switches. End-of-stroke deceleration is handled by fixed TPU bumper pads, and the rear features a CM round-end cover. For sizing reference, the net pull yields a safe working load of roughly 160 N, or about 13.6 kg of vertical lift with a 2:1 safety margin.

Where the Airtac MTF Mini Cylinder MTF32X20CM Is Used
Tensioning Mechanism
Uses the 266.8 N air retraction to pull and hold a belt or cable taut, automatically releasing the tension by springing out to the extended position when air is removed.
Fail-Safe Open Valve
Keeps a process line open by default via the internal spring, using the 1/4 inch air port to pull the linkage closed only when the system is actively pressurized.
Clamp Release
Holds a packaging fixture open at rest with its 20 mm stroke, pulling back to allow part insertion when actuated, ensuring the clamp opens if pneumatic power fails.
Is the Airtac MTF Mini Cylinder MTF32X20CM the Right Cylinder?
When sizing this 32 mm bore, compare its 266.8 N pull at 0.5 MPa against the smaller MTF25, which provides 153.6 N, or the larger MTF40, which delivers 434.8 N. Choose this model when a mechanism must fail to the extended position on air loss, such as a spring-open, air-close gate or a tensioning rig that releases tension upon venting. Ensure your air supply can reliably exceed the 0.2 MPa minimum required to overcome the spring force during retraction.
Mounting flexibility is provided through LB foot, FA flange, SDB pivot, and TC trunnion brackets. Because this base configuration has no internal magnet, it cannot accept CMSG, DMSG, or EMSG sensors; select the -S variant if position feedback is required for your automation sequence.
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 MTF32X20CM FAQ
The net pull force is 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 internal return spring and retract the 12 mm rod.
No, this base SKU does not include a magnet and cannot accept CMSG, DMSG, or EMSG switches. You must select the -S magnet option for position sensing. The spring always returns the rod to the extended position on air loss and will not hold a mid-stroke load.
