The AirTAC AirTAC MBL50X450U Mini Cylinder | 50mm Bore 450mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 450mm 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 MBL50X450U is a compact double-acting aluminum mini round cylinder engineered for tight machine spaces. It features a 50mm bore and a 450mm stroke, generating 981 N of push force and 881 N of pull force at 0.5 MPa. The U suffix designates a flat-end rear cover, providing a rigid fixed mounting footprint ideal for straight-line transfer tasks. This genuine AirTAC component relies on a riveted rolling-packed barrel construction, meaning the front and back covers are crimped to the tube for a lightweight, space-saving profile rather than using heavy tie-rods.
Inside, the unit utilizes a heterogeneous two-way piston seal that retains grease for long operational life, paired with a carbon-steel piston rod hardened with 20 μm chrome plating to resist wear and corrosion. Because this SKU lacks the -S suffix, it has no built-in magnet and cannot support a CMSG, DMSG, or EMSG position sensor. The end-of-stroke deceleration is handled by a fixed rubber bumper, which softens impact but does not lock the rod in place if air pressure drops.

Drives a folding mechanism on a packaging line, using the 981 N push force at 0.5 MPa to tuck heavy cardboard flaps before tape sealing.
Pushes small plastic parts out of a tight injection mold cavity, where the compact 50mm aluminum body fits within the press tooling.
Acts as a low-profile diverter arm on a packaging conveyor, extending 450mm to redirect heavy product boxes between processing lanes.
If 881 N of pull force is insufficient, stepping up to the 63mm bore yields 1457 N of pull at 0.5 MPa; conversely, scaling down to the 40mm bore provides 528 N of pull for lighter loads. This MBL50X450U uses a G1/4 port and PT tapered port threads. The fixed rubber bumper absorbs end-of-stroke shock, but if your application requires adjustable end-position damping for heavier moving masses, upgrade to the MBLC variant. Note that a plain MBL does not hold its load when air pressure is lost or exhausted—the rod will drift. Use an external rod lock or pilot-operated check valve if position holding is critical.
At a 450mm stroke, the 16mm rod is highly susceptible to bending under side loads. To prevent premature seal wear and rod-bearing failure, pair this cylinder with an external linear guide, select a CA pivot back cover for arcing motions, or switch to the MBLD double-rod anti-rotation type.
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 is 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa.
No. The base MBL uses a fixed rubber bumper to soften end-of-stroke impact, not an adjustable air cushion (for that, use the MBLC variant). Also, because this SKU lacks the -S suffix, it has no internal magnet and cannot accept CMSG, DMSG, or EMSG sensor switches.
