The AirTAC AirTAC MBL63X450U 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 MBL63X450U is a compact double-acting aluminum mini round cylinder engineered to deliver substantial thrust in restricted machine envelopes. Operating at 0.5 MPa, it generates 1558 N of push force and 1457 N of pull force, making this 63mm bore variant the heaviest hitter in the MBL family before stepping up to a full ISO 15552 profile cylinder. The 450mm stroke provides extensive linear travel for part ejection or robotic gating while maintaining a lightweight footprint.
This SKU features a rigid U flat-end back cover for fixed rear mounting. Because it lacks the -S suffix, no CMSG, DMSG, or EMSG position sensor can be fitted. The cylinder relies on a fixed rubber bumper to soften end-of-stroke impacts rather than an adjustable air cushion. Its heterogeneous two-way piston seal actively retains grease, and the carbon-steel rod features 20 um hard-chrome plating for wear resistance. The riveted rolling-packed aluminum barrel is permanently crimped, ensuring a light yet robust body that is not designed to be disassembled in the field.

Uses the 1558 N push force at 0.5 MPa to positively eject heavy molded plastic parts from a die, fitting within the tight mold platen clearance where a larger cylinder cannot.
Leverages the 450mm stroke to push heavy pallets onto a secondary packaging line, relying on the rigid U flat-end back cover to maintain alignment under high arc loads.
Employs the 318 kgf maximum theoretical force to lift and stack dense corrugated cardboard bales, using the hard-chrome plated rod to resist dust abrasion.
This 63mm bore provides the maximum thrust available in the MBL line (1558 N push at 0.5 MPa). If you need less force, step down to the 50mm bore, which offers 981 N of push force. If you require a larger standard profile cylinder, you must step outside the MBL series to an ISO 15552 tie-rod alternative. For rapid moves with heavy 318 kgf loads at 1.0 MPa, consider the MBLC variant, which adds an adjustable air cushion to prevent end-cap damage. If you only need spring-extend or spring-retract action, the MSBL or MTBL single-acting types are available up to the 40mm bore size.
With a 450mm stroke on a Ø16mm rod, this cylinder is highly susceptible to side-load bending and rod-bearing wear. You must support the load with an external guide rail, use a CA pivot back cover for arcing movements, or switch to the MBLD double-rod anti-rotation type. Additionally, the fixed rubber bumper only softens impact; it does not hold the load. If air pressure drops, the rod will drift and drop, so install an external pilot-operated check valve for position holding. Replacement parts require specifying the 63mm bore, 450mm stroke, G1/4 port, PT thread, and U flat-end cover.
Quick checklist
At 0.5 MPa, the push force is 1558 N and the pull force is 1457 N. At 0.7 MPa, the push force is 2181 N. The maximum theoretical force is 318 kgf at 1.0 MPa. It uses a G1/4 port with a PT tapered thread form, a Ø16mm rod, and an M14x1.5 rod-end thread.
No. The base MBL63X450U uses a fixed rubber bumper, not an adjustable air cushion; you must upgrade to the MBLC variant for adjustable cushioning. Additionally, this specific SKU lacks the -S magnet suffix, meaning no CMSG, DMSG, or EMSG sensor switch can be installed for rod position detection.
