The AirTAC Airtac MTBL Single Acting Aluminum Alloy Mini Cylinder MTBL40X60SCA is a genuine single acting, pull (spring extend) aluminum-barrel mini round cylinder with a Ø40mm bore and 60mm stroke, G1/4 air ports and a fixed rubber bumper. Air drives the pull (work) stroke and the spring returns the rod — it rests extended on air loss.
The AirTAC MTBL40X60SCA is a compact single-acting pull-type mini cylinder with a 40mm bore and 60mm stroke. Air retracts the Ø16mm hard-chrome carbon-steel rod, while an internal spring extends it. It yields a usable pull force of 339.1 N at 0.5 MPa and 550.1 N at 0.7 MPa. The riveted rolling-packed aluminum barrel keeps weight low while housing a grease-retaining two-way piston seal. Overall length follows A + 2 x stroke, making it longer than a double-acting counterpart.
This SKU features a built-in magnet (-S) for CMSG reed or DMSG/EMSG electronic position sensing, plus a CA pivot/clevis back cover that swings on a pin to absorb arcing loads. It uses a G1/4 port. A fixed rubber bumper absorbs end-of-stroke impact, as single-acting designs lack adjustable air cushions. The fail-safe home position is fully extended, returning there safely upon air loss.

Single-acting minimum working pressure is 0.2 MPa (the air must overcome the return spring). Do not apply an external load during the spring return stroke. Thread options: PT / G / NPT.
| Pressure | Pull force (net of spring) |
|---|---|
| 0.5 MPa | 339.1 N |
| 0.7 MPa | 550.1 N |
These are the usable single-acting forces after the return spring — lower than a same-bore double-acting MBL. Size with a margin.

Pulls a stamped metal blank inward out of a die with 339.1 N at 0.5 MPa, relying on the spring to safely push the ejector pin back out when air is cut.
Draws a sliding machinery drawer closed against tension, with the CA pivot bracket absorbing slight misalignment during the 60mm pull stroke.
Holds a safety guard open by pulling a pin back; the spring-extend fail-safe home automatically releases the guard to the open position on air loss.
Step down to the 32mm bore if your load is lighter, which provides 224.8 N at 0.5 MPa, or step up if you need more force—though 40mm is the largest single-acting pull option in this series. Choose this MTBL pull type over the MSBL push type when your mechanism requires a fail-safe extended rest position rather than a retracted one. The internal spring opposes the air stroke, so a minimum 0.2 MPa operating pressure is required to overcome it. Operating range is 0.2-1.0 MPa with speeds of 50-800 mm/s. Never apply external load to the spring (extend) return stroke. To replace this unit, match the 40mm bore, 60mm stroke, G1/4 port, PT thread, CA back cover, and -S magnet.
Quick checklist
This 40mm bore cylinder provides a usable pull force of 339.1 N at 0.5 MPa and 550.1 N at 0.7 MPa. It requires a minimum operating pressure of 0.2 MPa to overcome the return spring, with a maximum operating pressure of 1.0 MPa.
The CA back cover acts as a pivot clevis that swings on a pin to accommodate arcing or angular loads. The -S code indicates a built-in magnet for use with CMSG reed or DMSG/EMSG electronic sensor switches to detect rod position. On air loss, the spring drives the rod to its fail-safe extended home.
