The AirTAC AirTAC MBL50X40SCA Mini Cylinder | 50mm Bore 40mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 40mm 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 MBL50X40SCA 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, making this 40 mm stroke variant ideal for short, high-impact linear motions. The riveted rolling-packed barrel crimps the front and rear covers directly to the tube, yielding a lightweight body that is not designed to be disassembled like a traditional tie-rod cylinder.
This specific SKU includes a CA pivot (clevis) back cover, allowing the cylinder body to swing on a pin to accommodate arcing or angular loads. It is factory-fitted with a built-in magnet (-S) for use with AirTAC CMSG, DMSG, and EMSG sensor switches to detect rod position. The carbon-steel piston rod features a 20 um hard-chrome plating for high wear and corrosion resistance, while a heterogeneous two-way piston seal retains grease for extended operational life.

Drives a short-stroke swinging diverter gate on a packaging conveyor, utilizing the 981 N push force to reliably redirect heavy cardboard cartons at high speed.
Ejects small metal stamped parts from a progressive die mold, where the CA pivot back cover absorbs angular misalignment and the compact 40 mm stroke fits a tight press bed.
Acts as a pneumatic stop gate for heavy pallets on a roller track, using the 881 N pull force to retract the barrier and release the palletized load.
Stepping down in bore size, the adjacent 40 mm variant provides 628 N push force at 0.5 MPa, suitable if your application requires less thrust. Stepping up, the 63 mm bore offers 1558 N push force at 0.5 MPa for heavier loads. The base MBL uses a fixed rubber bumper to soften end-of-stroke impact; for adjustable air cushioning to handle faster cycling or heavier moving masses, select the MBLC variant instead.
Because the standard MBL lacks a physical lock, the rod will drift or drop if air pressure is lost or the valve is centered; use an external rod lock or pilot-operated check valve if the load must be held safely without live pressure. This SKU features a 50 mm bore, 40 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 of push force and 881 N of pull force. At 0.7 MPa, the push force increases to 1374 N, with a maximum theoretical force of 200 kgf at 1.0 MPa. It uses a Ø16 mm carbon steel rod with an M14x1.5 rod-end thread.
The base MBL has a fixed rubber bumper and does not feature an adjustable air cushion; if you need adjustable cushioning for heavier loads, choose the MBLC variant. This specific SKU includes a built-in magnet (-S), allowing you to mount CMSG, DMSG, or EMSG sensor switches for rod position detection.
