The AirTAC AirTAC MBL50X350SU Mini Cylinder | 50mm Bore 350mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 350mm 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 MBL50X350SU 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 50 mm bore, 350 mm stroke variant ideal for driving heavier slides or lifts in restricted envelopes. The riveted rolling-packed barrel keeps the overall body light and small, though it is not designed to be disassembled and rebuilt like a traditional tie-rod cylinder. This SKU includes a built-in magnet (-S) for non-contact rod position sensing using AirTAC CMSG (reed) or DMSG / EMSG (solid-state) switches.
The U flat-end back cover provides a rigid, fixed rear mounting face to resist play during high-force strokes. A heterogeneous two-way piston seal retains grease for long service life, while the carbon-steel piston rod features 20 µm hard-chrome plating for wear and corrosion resistance. The base MBL relies on a fixed rubber bumper to soften end-of-stroke impact rather than an adjustable air cushion.

Raises and lowers an angled conveyor section in a PCB assembly line. The 981 N push force at 0.5 MPa easily lifts the gate mechanism, while the 350 mm stroke provides the vertical travel needed for tall component clearance.
Pushes corrugated cardboard dividers into a palletizing cassette. The U flat-end back cover mounts rigidly to the machine frame, and the 350 mm stroke accommodates the full width of the packaging module.
Actuates a sliding shuttle stage in a semiconductor testing fixture. The built-in -S magnet pairs with a DMSG solid-state switch to confirm stroke endpoints without adding bulky external sensors to the compact chamber.
This 50 mm bore pushes 981 N and pulls 881 N at 0.5 MPa. If your payload is lighter, step down to the 40 mm bore (628 N push) to save space; if you need more thrust, the 63 mm bore offers 1558 N. For applications requiring end-of-stroke velocity tuning, choose the MBLC variant with its adjustable air cushion instead of the fixed rubber bumper. The -S magnet on this unit enables CMSG or DMSG sensor feedback for cycle validation.
At 350 mm of stroke, the Ø16 mm piston rod is highly susceptible to bending under side loads. Use an external guide rail to support the load, or pivot the cylinder using a CA back cover with an SDB bracket to absorb angular misalignment. The MBLD double-rod type is another option to prevent rod deflection and rotation. A plain MBL cannot hold a load if air pressure drops—the rod will drift. Add an external pilot-operated check valve or rod lock for fail-safe positioning.
Quick checklist
At 0.5 MPa it pushes 981 N and pulls 881 N. At 0.7 MPa the push force is 1374 N, with a theoretical maximum of 200 kgf at 1.0 MPa. The double-acting speed range is 30-800 mm/s.
No, the base MBL uses a fixed rubber bumper to soften end-of-stroke impact, not an adjustable cushion screw. If your 350 mm stroke moves a heavy mass at high speed and requires deceleration tuning, select the MBLC variant which features an adjustable air cushion.
