Airtac MTF Mini Cylinder MTF40X60U
The AirTAC Airtac MTF Mini Cylinder MTF40X60U is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø40mm 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.

About the Airtac MTF Mini Cylinder MTF40X60U
Delivering a substantial 434.8 N of net pull force at 0.5 MPa, this AirTAC MTF40X60U is a JIS-standard round-body mini cylinder built for single-acting pull operation. An internal spring normally holds the 16 mm rod extended, while supplying air to the 1/4 inch port retracts it. Because air only pulls, the unit fails safely to the extended position upon air loss, making it ideal for spring-open tasks. The SUS304 stainless barrel and riveted aluminium covers yield a shorter mounting envelope than an ISO 6432 cylinder of identical bore and stroke.
This 40 mm bore, 60 mm stroke configuration uses fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable cushion. As this specific SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG position switches. For sizing tension applications, the effective working load is roughly 261 N (about 60 percent of the 0.5 MPa rating), which translates to lifting or holding approximately 22.2 kg with a 2:1 safety margin.

Where the Airtac MTF Mini Cylinder MTF40X60U Is Used
Heavy Tensioning
Pulls and secures heavy straps or cables with a safe working load near 261 N, releasing tension automatically when air pressure drops.
Fail-Safe Gates
Holds a 40 mm bore mechanism open via spring force; air retracts the latch to close, ensuring the gate springs open during an air loss event.
Vertical Retraction
Lifts or counter-holds loads up to 22.2 kg against gravity using pneumatic pull, relying on the spring to lower the mass safely.
Is the Airtac MTF Mini Cylinder MTF40X60U the Right Cylinder?
When sizing this 40 mm bore model, compare its 434.8 N pull at 0.5 MPa against the next size down: the MTF32 provides 266.8 N. Since 40 mm is the largest available MTF bore, exceeding this capacity requires a different approach. Choose this single-acting pull cylinder when a mechanism must fail-safe to the extended position, such as a normally-closed gate or a tensioning rig that releases on air loss. Operation requires at least 0.2 MPa to overcome the return spring.
The U flat-end back cover on this unit suits direct rear mounting, while accessory options include LB foot, FA flange, SDB pivot, and TC trunnion brackets. If your sequence requires end-of-stroke confirmation, select the -S magnet variant to enable CMSG, DMSG, or EMSG sensors, as this base SKU cannot support them.
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 MTF40X60U FAQ
The net pull force is 434.8 N 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 internal return spring, with a maximum pressure limit of 1.0 MPa.
The spring constantly extends the rod, and air pressure pulls it back. On air loss, the spring drives the rod to the fully extended position; it cannot hold a load at an arbitrary mid-stroke point. The SUS304 stainless build resists mild corrosion.
