The AirTAC AirTAC MBL63X500U Mini Cylinder | 63mm Bore 500mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm 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 MBL63X500U is a double-acting aluminum mini round cylinder engineered for heavy-duty compact actuation. It generates 1558 N of push force and 1457 N of pull force at 0.5 MPa, making it the highest thrust class in the MBL series. The 500 mm stroke provides substantial travel length for machinery that requires long linear movements within a tight spatial envelope. This genuine AirTAC unit features a U flat-end back cover for rigid, fixed rear mounting.
Inside this riveted rolling-packed body, a heterogeneous two-way piston seal retains grease for extended operational life, while the Ø16 mm carbon-steel piston rod features 20 µm hard-chrome plating to resist wear and corrosion. The cylinder relies on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion. Because this specific SKU lacks the -S suffix, it cannot be fitted with a CMSG, DMSG, or EMSG position sensor switch.

Drives long-stroke 500 mm indexing arms to separate heavy pallets on packaging lines, utilizing the 1558 N push force to overcome friction without requiring a large profile cylinder.
Extends 500 mm to push large plastic injection molded parts out of a tight machine cavity, where the rigid U flat-end back cover mounts flush to the press frame.
Actuates a 500 mm vertical lift mechanism in compact sortation conveyors, relying on the maximum 318 kgf theoretical force to raise loaded totes.
Select the MBL63X500U when your application demands the maximum standard thrust available in this compact frame, pushing 1558 N at 0.5 MPa. If you need slightly less force and a smaller footprint, step down to the 50 mm bore, which provides 981 N of push force. As the largest standard bore in this series, there is no larger MBL option; for even higher loads, consider moving to an ISO 15552 profile cylinder. For long-stroke setups like this 500 mm extension, the small Ø16 mm rod has low side-load tolerance; you must use an external guide rail, a CA pivot back cover, or the MBLD double-rod anti-rotation type to prevent rod-bearing bending.
The base MBL design uses a fixed rubber bumper, not an adjustable cushion screw, so heavy masses moving at high speeds may require the MBLC variant for end-of-stroke deceleration. Furthermore, this cylinder does not hold its load when air pressure is lost or exhausted—the rod will drift. If gravity or external forces pose a hazard, install an external rod lock or a pilot-operated check valve. Replacement parts must match the 63 mm bore, 500 mm stroke, G1/4 port, PT thread, and U flat-end back cover.
Quick checklist
At 0.5 MPa it delivers 1558 N push and 1457 N pull; at 0.7 MPa it delivers 2181 N push. The maximum theoretical force is 318 kgf at 1.0 MPa. The double-acting speed range is 30-800 mm/s.
No, this SKU has a fixed rubber bumper, not an adjustable air cushion (you would need the MBLC variant for that). It also lacks the -S magnet suffix, meaning it cannot accept CMSG, DMSG, or EMSG electronic position sensors.
