The AirTAC AirTAC MBL40X80SCA Mini Cylinder | 40mm Bore 80mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø40mm bore and 80mm stroke, G1/4 air ports and a fixed rubber bumper. Its compact riveted body suits push, hold and clamp motion in tight machine spaces.
The AirTAC MBL40X80SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. At 0.5 MPa it generates 628 N of push force and 528 N of pull force, making this 80 mm stroke unit ideal for mid-range actuation. The body utilizes a riveted rolling-packed barrel where the covers are crimped to the tube, ensuring a lightweight footprint, though it is not designed to be disassembled like a tie-rod cylinder.
This SKU includes a CA pivot (clevis) back cover that swings on a pin to accommodate arcing and angular loads. It also features a built-in magnet (-S) for compatibility with AirTAC CMSG reed and DMSG/EMSG electronic sensor switches. The carbon-steel piston rod has a 20 um hard-chrome plating for wear resistance, paired with a heterogeneous two-way piston seal that retains grease for extended operational life.

Swings a diverting arm on a packaging line using its 628 N push force, with the CA clevis back cover allowing the mechanism to pivot smoothly during the arcing motion.
Regulates yarn tension on a textile loom across the 80 mm stroke, relying on the DMSG electronic sensor switch to confirm rod position for process control.
Actuates a sorting gate on a high-speed bottling line, where the 528 N pull force reliably retracts the 16 mm chrome-plated rod against spring-loaded resistance.
If you need less force, step down to the 32 mm bore (402 N push at 0.5 MPa); if your application requires more power, step up to the 50 mm bore (981 N push at 0.5 MPa). Because this is an 80 mm stroke under 300 mm, side-load bending is less severe, but the small 16 mm rod still has low side-load tolerance—use an external guide for heavy radial loads. The base MBL uses a fixed rubber bumper to soften end-of-stroke impact; for adjustable air cushioning, select the MBLC variant.
Keep in mind that a plain double-acting cylinder does not hold its load when air pressure is lost or the valve is centered; the rod will drift or drop. If your machine requires position holding without live pressure, add an external rod lock or a pilot-operated check valve. This specific configuration includes a CA pivot back cover, a built-in magnet, a G1/4 port, and a default PT thread.
Quick checklist
At 0.5 MPa, this 40 mm bore cylinder provides 628 N of push force and 528 N of pull force. At 0.7 MPa, the push force increases to 880 N. The maximum theoretical force is 128 kgf at 1.0 MPa.
No, the base MBL uses a fixed rubber bumper to absorb end-of-stroke impact, not an adjustable air cushion. If your application requires adjustable cushioning for heavier or faster moving loads, you should select the MBLC variant.
