Airtac MTF Mini Cylinder MTF40X10CM
The AirTAC Airtac MTF Mini Cylinder MTF40X10CM is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø40mm bore and 10mm 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 MTF40X10CM
Delivering 645.8 N of pull at 0.7 MPa, this 40 mm bore unit is built for heavy-duty tensioning and retraction. The AirTAC MTF40X10CM is a JIS-standard round-body mini cylinder featuring a SUS304 stainless barrel and riveted aluminium covers. It operates as a single-acting pull type: an internal spring holds the rod extended, while supplying air to the 1/4" port retracts it. This fail-safe-to-extended design is perfect for spring-open, air-close operations.
Because the spring constantly pushes outward, the quoted 434.8 N pull at 0.5 MPa is already net of that spring force. For sizing, this yields a safe working load of roughly 261 N, or about 22.2 kg of vertical lift with a 2:1 margin. The riveted construction is shorter than an ISO 6432 cylinder for the same envelope, saving space. This specific SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors without upgrading to an -S variant. It relies on fixed TPU bumper pads for end-of-stroke deceleration across its 50-800 mm/s speed range.
When sizing this 40 mm bore, step down to an MTF32 if your task requires only 266.8 N of pull at 0.5 MPa, as no larger MTF bore exists for heavier loads. Single-acting pull mechanics fit applications needing a return-to-extended fail-safe, such as tensioning or holding gates open. Remember the 0.2 MPa pressure floor required to overcome the spring. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion, and this model includes a CM round-end back cover. Because this SKU has no -S magnet, position sensing is unavailable.

Where the Airtac MTF Mini Cylinder MTF40X10CM Is Used
Heavy-Duty Tensioning
Pulls with 434.8 N at 0.5 MPa to maintain high cable or web tension, releasing the load only when air is applied.
Fail-Safe Gate Opening
Holds a 40 mm bore access door extended during air loss; air retracts the 16 mm rod to permit passage.
Spring-Return Clamping
Keeps a workpiece clamped by spring force, using air to retract the M14x1.5 rod for quick part loading.

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 MTF40X10CM FAQ
It generates 434.8 N of pull at 0.5 MPa and 645.8 N at 0.7 MPa. Operating pressure is 0.2-1.0 MPa, with a 0.2 MPa floor required to overcome the internal spring.
The spring drives the rod to the extended position at rest and on air loss, failing safe open. It cannot hold a mid-stroke load; use a double-acting MF with an external rod lock for that.
