The AirTAC AirTAC MBL50X150SCA Mini Cylinder | 50mm Bore 150mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 150mm 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 MBL50X150SCA is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It delivers a robust 981 N push force at 0.5 MPa across its 150 mm stroke, making it ideal for moving heavier jigs or small platens. The riveted rolling-packed barrel keeps the body light and compact, though it is not designed to be disassembled like a tie-rod cylinder. Inside, a heterogeneous two-way piston seal retains grease for long service life, while the carbon-steel rod features 20 μm hard-chrome plating for wear and corrosion resistance.
This specific SKU includes a built-in magnet (-S) for compatibility with AirTAC CMSG reed and DMSG/EMSG electronic sensor switches to detect rod position. It also features a CA pivot (clevis) back cover, allowing the cylinder to swing on a pin to accommodate arcing or angular loads. The end-of-stroke deceleration relies on a fixed rubber bumper, not an adjustable air cushion.

Actuates a pusher arm to index bar stock into the lathe collet, where the 981 N force securely drives heavy material past the guide bushing.
Swings a diverter gate on a packaging conveyor, using the CA pivot back cover to absorb angular stress during high-speed lane routing.
Ejects small plastic parts from tight mold cavities, using the 150 mm stroke to fully clear the tooling before the robot extracts the parts.
At 0.5 MPa, this 50 mm bore generates 981 N of push force. If your application requires less force, the next size down is the 40 mm bore, which provides 628 N of push force. For heavier payloads, the 63 mm bore offers 1558 N. Because this is a 150 mm stroke, the 16 mm rod has a moderate unsupported length; for longer strokes, use an external guide or consider the MBLD double-rod type to prevent rod bending under side load.
If you need adjustable end-speed control, select the MBLC variant instead of the fixed rubber bumper. Remember that a standard MBL does not hold its load when air pressure is lost or the valve is centered; the rod will drift. Use an external rod lock or pilot-operated check valve for fail-safe position holding. This SKU's exact replacement attributes are: 50 mm bore, 150 mm stroke, G1/4 port, PT thread, CA pivot back cover, and a built-in magnet.
Quick checklist
At 0.5 MPa, this 50 mm bore cylinder provides 981 N push and 881 N pull force. At 0.7 MPa, the push force is 1374 N, with a maximum theoretical force of 200 kgf at 1.0 MPa. It uses a G1/4 port and features an M14x1.5 rod-end thread on a 16 mm rod.
No, the base MBL features a fixed rubber bumper to soften 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 instead.
