Airtac MTF Mini Cylinder MTF40X100CM
The AirTAC Airtac MTF Mini Cylinder MTF40X100CM is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø40mm bore and 100mm 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 MTF40X100CM
Delivering a robust 434.8 N of net pull force at 0.5 MPa, this JIS-standard round-body mini cylinder is engineered for single-acting tension and fail-safe-open tasks. The internal spring constantly pushes the 16 mm rod out to its extended rest, while supplying 1/4" port air retracts it. Because the spring holds the rod out, any loss of air pressure automatically drives the mechanism back to the extended position. The SUS304 stainless barrel and riveted aluminium covers shrug off mild washdowns, and the riveted rolling-packed construction yields a shorter envelope than an ISO 6432 unit of identical bore and stroke.
This specific SKU lacks the -S magnet option, so it cannot host CMSG, DMSG, or EMSG position switches. For sizing context, the 40 mm bore pulls 645.8 N at 0.7 MPa. A practical buyer insight: with a conservative 2:1 safety margin, this bore yields an effective vertical lift capacity of about 22.2 kg (safe working load roughly 261 N) based strictly on the 0.5 MPa figure. End-of-stroke deceleration relies on fixed TPU bumper pads rather than an adjustable cushion.

Where the Airtac MTF Mini Cylinder MTF40X100CM Is Used
Fail-Safe Gate Closing
Uses the 434.8 N pull to pneumatically draw a guard gate shut, while the spring automatically pushes it back open if the air supply drops.
Constant Tensioning
Maintains steady pulling tension on wiring or web materials during processing, relying on the spring to keep the load taut at rest.
Spring-Return Lifting
Pulls a light 20 kg fixture upward via air, then safely lowers the load by allowing the spring to ease the rod back out to its extended state.
Is the Airtac MTF Mini Cylinder MTF40X100CM the Right Cylinder?
When sizing this 40 mm bore, look both directions: step down to an MTF32 if 266.8 N of pull at 0.5 MPa is sufficient, as 40 mm is the largest available MTF bore. Choose this single-acting pull type for spring-open / air-close routines, constant tensioning, or return-to-extended fail-safe logic. Remember the system requires at least 0.2 MPa of air pressure to overcome the internal spring before retraction begins. The round CM back cover suits compact pivot arrangements, and you can pair the body with LB foot, FA flange, SDB pivot, or TC trunnion mounts. Because this exact configuration ships without a magnet, order an -S variant if your sequence demands CMSG, DMSG, or EMSG sensor feedback.
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 MTF40X100CM FAQ
This 40 mm bore cylinder provides a net pull force of 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 spring and begin retracting the rod.
No, this specific SKU does not include a magnet. You must select an -S variant to use CMSG, DMSG, or EMSG magnetic switches. Additionally, the spring constantly extends the rod, so it fails to the extended position on air loss rather than holding a mid-stroke load.
