The AirTAC AirTAC MBL50X350U 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 MBL50X350U is a double-acting aluminum mini round cylinder engineered for compact spaces. It delivers a robust 981 N push force at 0.5 MPa, making this 350 mm stroke variant ideal for reaching deep into machinery where standard profile bodies cannot fit.
This SKU features a rigid U flat-end rear cover for fixed foot mounting. The riveted rolling-packed barrel permanently crimps the covers to the tube, creating a lightweight, sealed unit that is not designed to be disassembled. The carbon steel piston rod has a 20 um hard-chrome plating to resist wear, paired with a heterogeneous two-way piston seal that retains grease for a long service life. Because this specific model lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor.

Related variants: MBLC (adjustable cushion), MBLD (double rod), MBLJ (adjustable stroke), MSBL/MTBL (single acting).
Pushes corrugated cardboard flaps on a packaging line using 981 N of thrust, fitting neatly into the narrow side frame of the conveyor.
Drives a flying probe over a 350 mm travel distance to contact test pads on large server motherboards without requiring a bulky ISO cylinder.
Ejects small finished parts from a machining cell into a tote, utilizing the rigid U flat-end mount to anchor firmly to the machine bed.
Stepping down, the 40 mm bore offers 628 N push at 0.5 MPa, while stepping up to the 63 mm bore yields 1558 N. The base MBL uses a fixed rubber bumper to soften end-of-stroke impacts; for heavier 350 mm moves requiring adjustable air cushioning, select the MBLC variant. Note that a plain MBL does not hold its position if air pressure is lost—the rod will drift—so use an external rod lock for safety-critical loads.
With a 350 mm stroke, the Ø16 mm rod is highly susceptible to bending under side loads. To prevent premature seal wear and rod bearing failure, guide the load externally or pivot the cylinder using an SDB bracket. For strict anti-rotation requirements, consider the MBLD double-rod type. Replacement match: 50 mm bore, 350 mm stroke, G1/4 port, PT thread, U back cover, no magnet.
Quick checklist
At 0.5 MPa it provides 981 N push and 881 N pull. At 0.7 MPa, push increases to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa, and it operates at speeds of 30-800 mm/s.
No. The base MBL uses a fixed rubber bumper, not an adjustable air cushion (you would need the MBLC variant for that). Additionally, because this SKU lacks the -S magnet suffix, it cannot accept CMSG, DMSG, or EMSG electronic or reed sensor switches.
