Airtac MTF Mini Cylinder MTF40X50CA
The AirTAC Airtac MTF Mini Cylinder MTF40X50CA is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø40mm bore and 50mm 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 MTF40X50CA
Delivering a robust 434.8 N pull force at 0.5 MPa (645.8 N at 0.7 MPa), this 40 mm bore JIS-standard round-body mini cylinder is built for demanding tensioning tasks. The MTF40X50CA utilizes a SUS304 stainless barrel with riveted aluminium covers, resisting mild corrosion and washdown environments. It features a 1/4" port and a 16 mm rod with an M14x1.5 male thread.
Because it is a single-acting pull type, an internal spring holds the rod extended at rest, while compressed air retracts it. This means the cylinder fails safely to the extended position upon air loss, making it perfect for spring-open applications. For sizing, its safe working load is roughly 261 N, and it can vertically lift about 22.2 kg with a 2:1 margin. This base SKU lacks a magnet, so it cannot accept position sensors; adding the -S option enables CMSG, DMSG, or EMSG switches.

Where the Airtac MTF Mini Cylinder MTF40X50CA Is Used
Heavy Cable Tensioning
Pulls and maintains tension on heavy cabling or wire bundles, using its 434.8 N pull force to retract and secure the load against constant drag.
Fail-Safe Gate Closure
Holds a heavy access gate open with air pressure, then automatically springs back to the extended position to lock the gate closed if the air supply drops.
Retracting Heavy Pallets
Draws back a loaded pallet stopper or diverter arm, safely handling materials up to 22.2 kg vertically with a 2:1 safety margin.
Is the Airtac MTF Mini Cylinder MTF40X50CA the Right Cylinder?
When sizing this 40 mm bore unit, compare it directly against the smaller MTF32, which provides 266.8 N of pull at 0.5 MPa. If your application requires less force, the MTF32 is more compact, but for heavier loads needing that 434.8 N pull, this is the largest bore available in the MTF family. A minimum operating pressure of 0.2 MPa is required to overcome the internal spring.
This specific configuration includes a CA rear pivot cover, ideal for clevis mounting. It uses fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable air cushion. For applications needing mid-stroke load holding, pair a double-acting MF cylinder with an external rod lock, as this spring-return unit only drives to the extended rest position on air loss.
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 MTF40X50CA FAQ
This single-acting pull cylinder generates 434.8 N of pull force at 0.5 MPa and 645.8 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the return spring, with a maximum pressure of 1.0 MPa and a proof pressure of 1.5 MPa.
No, this specific SKU does not include a magnet and cannot accept CMSG, DMSG, or EMSG switches. You must select the -S variant for position sensing. Additionally, it features a CA pivot cover and fixed TPU bumper pads instead of an adjustable cushion.
