The AirTAC AirTAC MBL50X15SU Mini Cylinder | 50mm Bore 15mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 15mm 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 MBL50X15SU is a double-acting aluminum mini round cylinder engineered for compact spaces requiring high force. Operating at 0.5 MPa, it yields 981 N of push force and 881 N of pull force, making this 15 mm stroke unit ideal for short, heavy pressing or clamping tasks. The U flat-end back cover provides a rigid rear mounting face for straightforward fixed attachment.
Unlike tie-rod cylinders, this unit features a riveted rolling-packed barrel that crimps the covers to the tube, ensuring a lightweight yet durable body that is not designed to be disassembled. The carbon-steel piston rod is treated with a 20 um hard-chrome plating for superior wear and corrosion resistance. Because this SKU includes the -S suffix, it contains a built-in magnet for non-contact position detection using AirTAC CMSG (reed), DMSG, or EMSG (solid-state) sensor switches.

Drives a short 15 mm stroke to press a wiper blade against a dense stencil frame, utilizing the 981 N push force to clear solder paste without flexing.
Pushes heavy-duty electronic headers into rigid housings on an assembly line, where the built-in magnet verifies proper insertion via a DMSG solid-state sensor.
Holds a corrugated carton flap firmly in place during a hot-melt glue cycle, taking advantage of the rigid U flat-end back cover to absorb the 881 N pull reaction.
Select this 50 mm bore when you need substantially more power than the 32 mm bore (which provides 402 N push at 0.5 MPa) but want a smaller footprint than a 63 mm bore offering 1558 N. The fixed rubber bumper softens end-of-stroke impact, but if your application involves fast cycling or heavy moving masses, step up to the MBLC variant for adjustable air cushioning. Keep in mind that a plain MBL does not hold its position if air pressure drops or the valve is centered; the rod will drift. Use an external pilot-operated check valve for fail-safe load holding.
This specific configuration features a G1/4 port with a PT tapered thread form, a rigid U flat-end back cover, and a built-in magnet for sensor tracking. The Ø16 mm rod and 15 mm stroke keep the acting mass low, but always ensure the rear mounting surface is perfectly square to prevent side-load binding.
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 operates at a speed range of 30-800 mm/s.
No, the base MBL50X15SU uses a fixed rubber bumper to soften end-of-stroke impacts, which cannot be adjusted. If your application requires adjustable air cushioning for heavier loads or faster speeds, you must use the MBLC variant.
