The AirTAC AirTAC MBL50X75U Mini Cylinder | 50mm Bore 75mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 75mm 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 MBL50X75U is a double-acting aluminum mini round cylinder engineered for tight machine spaces where traditional profile bodies cannot fit. It delivers a robust 981 N push force at 0.5 MPa (1374 N at 0.7 MPa) across its 75 mm stroke, making it well-suited for heavier mid-cycle positioning tasks. The U suffix denotes a rigid flat-end rear cover for secure fixed mounting.
Unlike tie-rod cylinders, this unit features a riveted rolling-packed barrel that permanently crimps the front and rear covers to the tube, minimizing weight and footprint. Inside, a heterogeneous two-way piston seal retains grease for long service life, while the Ø16 mm carbon-steel piston rod features 20 µm hard-chrome plating to resist wear and corrosion. Because this specific SKU lacks the -S suffix, it has no built-in magnet and cannot support a CMSG, DMSG, or EMSG position sensor.

Gates and diverts filled PET bottles on a high-speed packaging conveyor using 981 N of push force at 0.5 MPa within a narrow 75 mm stroke envelope.
Ejects small plastic injection-molded parts from a tight tooling cavity where the compact 50 mm aluminum barrel footprint prevents fixture clashes.
Pushes lightweight cardboard cases off a roller palletizer lane, relying on the rigid U flat-end back cover to withstand repeated axial impact loads.
If your application requires less force, step down to the Ø32 bore (402 N push @0.5 MPa); if you need more power, the Ø63 bore provides 1558 N. This base MBL model uses a fixed rubber bumper to soften end-of-stroke impact rather than an adjustable air cushion—choose the MBLC variant if you need screw-adjustable shock absorption for heavier moving loads. Additionally, the fixed rubber bumper is not a locking mechanism; the rod will drift if air pressure is lost, so fit an external pilot-operated check valve if the load must be held in place during an air drop.
Quick checklist
The Ø50 mm bore generates 981 N push and 881 N pull at 0.5 MPa, 1374 N push at 0.7 MPa, and a maximum theoretical force of 200 kgf at 1.0 MPa. It uses a G1/4 port, a Ø16 mm rod with an M14x1.5 rod-end thread, and operates at speeds of 30-800 mm/s.
This specific SKU lacks the -S magnet suffix, so a CMSG, DMSG, or EMSG sensor switch cannot be fitted. End-of-stroke cushioning relies on a fixed rubber bumper; for adjustable air cushioning, you must specify the MBLC variant.
