The AirTAC AirTAC MBL50X100SU Mini Cylinder | 50mm Bore 100mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 100mm 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 MBL50X100SU is a compact double-acting aluminum mini round cylinder built for tight machine spaces. It delivers 981 N of push force and 881 N of pull force at 0.5 MPa, making it well-suited for 100 mm stroke actuation in mid-sized assembly machinery. The U suffix denotes a rigid flat-end rear cover, providing a solid fixed mounting footprint rather than a swinging pivot joint. The S suffix indicates a built-in magnet, enabling position detection via CMSG reed or DMSG/EMSG electronic sensor switches.
Unlike tie-rod cylinders, this body uses a riveted rolling-packed aluminum barrel where the covers are crimped permanently to the tube, ensuring a lightweight, compact profile that cannot be disassembled for rebuilding. The Ø16 mm carbon-steel piston rod features 20 µm hard-chrome plating for wear and corrosion resistance, paired with a heterogeneous two-way piston seal that retains internal grease for long service life. End-of-stroke impact is absorbed by a fixed rubber bumper on the base MBL, not an adjustable air cushion.

Providing 981 N of push force over a 100 mm stroke, this cylinder reliably ejects plastic parts from mid-sized injection molds where machine clearance is strictly limited.
The compact 50 mm aluminum body and built-in magnet allow precise sensor-confirmed diverting of packaged boxes on a 24V conveyor belt without occupying excessive frame width.
Supplies 881 N of pull force at 0.5 MPa to hold down composite PCB routing blanks securely, while the rigid U-type flat-end back cover maintains strict parallel alignment.
If you need slightly less force, step down to the Ø32 bore, which provides 402 N of push at 0.5 MPa. For heavier loads, step up to the Ø63 bore, which yields 1558 N of push at 0.5 MPa. Because the U-style flat-end back cover mounts rigidly, it is ideal for straight-line pushing tasks where the load travels parallel to the rod. If your mechanism requires angular arcing or pivot motion, switch to the CA back cover variant and pair it with an SDB pivot bracket.
This SKU includes the -S magnet for use with CMSG, DMSG, or EMSG sensor switches. The port thread form is PT, and the port size is G1/4. Keep in mind that a plain double-acting cylinder does not hold its load if air pressure drops or the valve is centered; the rod will drift. Use an external pilot-operated check valve or rod lock if gravity loads must be safely suspended. For faster cycle speeds with heavier payloads, consider the MBLC variant, which adds an adjustable air cushion instead of the standard fixed rubber bumper.
Quick checklist
At 0.5 MPa, the push force is 981 N and the pull force is 881 N. At 0.7 MPa, the push force reaches 1374 N. The theoretical maximum force is 200 kgf at 1.0 MPa. The operating speed range for this double-acting cylinder is 30-800 mm/s.
No, the base MBL50X100SU uses a fixed rubber bumper to soften end-of-stroke impacts and cannot be adjusted. If your application requires adjustable end-of-stroke deceleration for heavier moving masses, upgrade to the AirTAC MBLC variant, which features an adjustable air cushion.
