The AirTAC AirTAC MBL63X450SCA Mini Cylinder | 63mm Bore 450mm Stroke is a genuine double-acting aluminum-barrel mini round cylinder with a Ø63mm 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 MBL63X450SCA 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 suitable for moving substantial jigs or workpieces within confined machinery envelopes. The 450 mm stroke provides extensive linear travel for part transfer or lifting tasks. This specific SKU features a CA pivot back cover, allowing the cylinder body to swing freely on a pin to accommodate arcing or angular loads during motion.
Unlike tie-rod bodies, the MBL utilizes a riveted rolling-packed aluminum barrel where the covers are crimped to the tube, yielding a lightweight profile that is not designed to be disassembled. The carbon-steel piston rod is hardened with 20 um chrome plating for wear and corrosion resistance. Because this model includes the -S suffix, it has a built-in magnet for non-contact position detection using AirTAC CMSG (reed), DMSG, or EMSG (solid-state) sensor switches. End-of-stroke energy is absorbed by a fixed rubber bumper, which softens impact but does not lock the rod in place if air pressure is lost.

Drives a 450 mm lift arm to lower heavy timber or steel pallets onto a roller conveyor, utilizing the 1558 N push force and CA pivot bracket to accommodate the arc of the lifting motion.
Actuates a long-stroke gantry arm to push heavy steel bar stock into a CNC lathe collet, where the 20 um chrome-plated rod withstands repetitive industrial cycling.
Raises a loaded shuttle platform 450 mm within a dense automated storage aisle, using the built-in -S magnet and a DMSG solid-state switch to confirm the top discharge position.
At 450 mm of stroke, this 63 mm bore cylinder produces 1558 N of push force at 0.5 MPa. If you need less force to avoid over-driving delicate parts, step down to the 50 mm bore, which provides 981 N of push force. If your application requires even heavier thrust, note that 63 mm is the largest bore in the MBL series, so exceeding 318 kgf at 1.0 MPa would require stepping up to a larger ISO 15552 profile cylinder. For applications needing precise end-of-stroke deceleration at these high forces over 450 mm, consider the MBLC variant, which replaces the fixed rubber bumper with an adjustable air cushion.
Because the stroke is 450 mm, the unsupported Ø16 mm piston rod is highly susceptible to bending under side loads. The CA pivot back cover on this SKU is an excellent choice here, as it allows the cylinder to swing and self-align, reducing bearing stress. For rigidly mounted setups facing heavy lateral loads, an external guide rail or the MBLD double-rod anti-rotation cylinder is strongly recommended. Remember that a plain MBL does not hold its position when air is exhausted; the rod will drift under load, so fit an external pilot-operated check valve if position retention is required.
Quick checklist
This 63 mm bore cylinder delivers 1558 N of push force and 1457 N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 2181 N, with a maximum theoretical force of 318 kgf at 1.0 MPa. It operates at speeds between 30 and 800 mm/s, uses a G1/4 port, and has a maximum standard stroke limit of 500 mm.
No, the base MBL features a fixed rubber bumper that only softens the end-of-stroke impact; it is not an adjustable air cushion (you would need the MBLC variant for that). Additionally, the bumper is not a locking mechanism. If air pressure is lost or the valve is centered, the rod will drift or drop, requiring an external rod lock or pilot-operated check valve to hold a load safely.
