The AirTAC AirTAC MBL50X500U Mini Cylinder | 50mm Bore 500mm is a genuine double-acting aluminum-barrel mini round cylinder with a Ø50mm bore and 500mm 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 MBL50X500U is a double-acting aluminum mini round cylinder engineered for compact machinery requiring a long 500 mm stroke. It generates 981 N of push force at 0.5 MPa, making it well-suited for moving heavier jigs or workpieces over extended distances. The U flat-end back cover provides a rigid, fixed rear mounting face to anchor the long body securely. Because this specific SKU lacks the -S suffix, it cannot accept a CMSG, DMSG, or EMSG position sensor switch.
Unlike tie-rod ISO cylinders, this actuator uses a riveted rolling-packed aluminum barrel where the covers are crimped directly to the tube, ensuring a lightweight yet durable construction that is not designed to be disassembled. The carbon-steel piston rod features a 20 um hard-chrome plating to resist wear and corrosion, while a heterogeneous two-way piston seal retains grease for a long service life. End-of-stroke impact is absorbed by a fixed rubber bumper, which softens the stop but does not lock the load in place.

Uses the 981 N push force at 0.5 MPa to eject heavy molded plastic parts from a tool over a 500 mm travel distance where space is strictly limited.
Actuates a long-stroke transfer arm to push heavy pallets between roller conveyor sections, relying on the rigid U flat-end back cover to brace the 500 mm stroke.
Raises a heavy loading bay gate via the 200 kgf maximum theoretical force, taking advantage of the full 500 mm extension to clear tall cargo.
At 0.5 MPa, this 50 mm bore provides 981 N of push and 881 N of pull force. If you need less force in a tighter footprint, step down to the 40 mm bore, which yields 628 N push at 0.5 MPa. For heavier loads requiring more thrust, step up to the 63 mm bore, providing 1558 N push at 0.5 MPa. If your application needs precise end-of-travel deceleration for those heavy 500 mm moves, select the MBLC variant for its adjustable air cushion instead of the fixed rubber bumper.
With a 500 mm stroke driven by a Ø16 mm rod, the unsupported piston rod is highly susceptible to bending under side loads. To prevent premature seal wear or rod damage, you must use an external guide, pair the cylinder with an SDB pivot bracket, or switch to the MBLD double-rod anti-rotation type. Additionally, the U flat-end back cover is a rigid mount; if your mechanism requires arcing or angular movement, change to the CA pivot back cover. Because this SKU has no -S magnet, you cannot attach any sensor for position feedback. Note that if air pressure is lost, the fixed rubber bumper will not hold the load, and the rod will drift.
Quick checklist
This 50 mm bore cylinder features a G1/4 port and a Ø16 mm rod. At 0.5 MPa it provides 981 N of push force and 881 N of pull force. At 0.7 MPa, the push force increases to 1374 N. The maximum theoretical force is 200 kgf at 1.0 MPa.
No, the base MBL50X500U uses a fixed rubber bumper to soften end-of-stroke impacts and cannot be adjusted like the air cushion on an MBLC variant. Additionally, because this SKU lacks the -S magnet suffix, you cannot mount a CMSG, DMSG, or EMSG sensor switch to detect rod position.
