The AirTAC AirTAC MBL50X25SCA Mini Cylinder | 50mm Bore 25mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 25mm 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 MBL50X25SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. At 50mm bore, it generates 981N push and 881N pull force at 0.5MPa, making it a robust choice for high-force clamping over its 25mm stroke. The riveted rolling-packed barrel permanently crimps the covers to the tube, delivering a lightweight body that cannot be disassembled like a standard tie-rod cylinder.
This specific SKU includes a built-in magnet (-S) for position sensing with CMSG reed or DMSG/EMSG electronic switches. It is fitted with a CA pivot back cover, allowing the cylinder body to swing on a pin to accommodate arcing or angular loads. The carbon-steel piston rod features 20um hard-chrome plating for wear resistance, and the heterogeneous two-way piston seal retains grease for extended operational life.

Related variants: MBLC (adjustable cushion), MBLD (double rod), MBLJ (adjustable stroke), MSBL/MTBL (single acting).
Drives short 25mm stroke pressing tasks in small-part assembly lines, utilizing the 981N push force at 0.5MPa to seat bearings or pins securely.
Powers a swinging diverter arm on a packaging conveyor, where the CA pivot back cover handles the angular arc of the routing mechanism perfectly.
Folds corrugated carton flaps in tight end-of-line packaging machinery, using the built-in magnet to confirm fold completion via a DMSG sensor.
If you need slightly less force, step down to the 40mm bore which provides 628N push at 0.5MPa. If your application requires even heavier thrust, the 63mm bore offers 1558N push at 0.5MPa. The CA pivot mount on this unit is ideal for accommodating lateral movement, but remember that a plain MBL does not hold its load if air pressure drops; use an external pilot-operated check valve for drop prevention. The port size is G1/4 with a PT thread form, and the rod end uses an M14x1.5 thread. Because the stroke is only 25mm, side-load bending is minimal, but the fixed rubber bumper means you must upgrade to the MBLC variant if you need adjustable end-of-stroke cushioning for heavier impacts.
Quick checklist
At 0.5MPa, this 50mm bore cylinder provides 981N push and 881N pull force. At 0.7MPa, the push force increases to 1374N. The maximum theoretical force is 200kgf when operated at the 1.0MPa pressure limit.
No, the base MBL50X25SCA uses a fixed rubber bumper to soften end-of-stroke impact and cannot be adjusted. If your application requires adjustable end-of-stroke deceleration for heavier loads, you must select the MBLC variant which features an adjustable air cushion.
