The AirTAC AirTAC MBL50X450SCA 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 MBL50X450SCA is a double-acting aluminum mini round cylinder engineered for tight machine spaces where high force and a long 450mm stroke are required. It delivers a robust 981N push and 881N pull at 0.5 MPa, utilizing a 50mm bore and a Ø16mm carbon-steel piston rod with 20µm hard-chrome plating for superior wear resistance. The riveted rolling-packed barrel keeps the body light and compact, though it is not designed to be disassembled like a tie-rod cylinder.
This specific SKU includes a built-in magnet (-S) for use with AirTAC CMSG, DMSG, or EMSG sensor switches to detect rod position, and features a CA pivot (clevis) back cover. The CA clevis allows the cylinder body to swing on a pin, accommodating arcing or angular loads. End-of-stroke impact is absorbed by a fixed rubber bumper rather than an adjustable air cushion (which would require the MBLC variant).

Drives the 450mm reach of a packaging robotic arm, utilizing the 981N push force to extend and tuck the assembly within a compact cell envelope.
Swings a sorting gate along a conveyor line, where the CA pivot back cover absorbs the angular momentum of the 450mm stroke redirecting heavy cartons.
Raises a tiered goods lift in an automated storage system, using the built-in magnet (-S) to trigger a DMSG solid-state sensor at the exact 450mm upper limit.
At 0.5 MPa, this 50mm bore provides 981N push force. If you need less force, the 40mm bore offers 628N push; if your application demands more, the 63mm bore provides 1558N push. The 450mm stroke on a mini cylinder with an Ø16mm rod requires careful mounting to prevent rod-bearing bending under side loads—use the CA pivot back cover, an external guide, or consider the MBLD double-rod type for anti-rotation. A plain MBL does not hold its position or load when air pressure is lost; the rubber bumper only softens the end impact, so add an external rod lock or pilot-operated check valve if the load must be held without live pressure. Replacement match: 50mm bore, 450mm stroke, G1/4 port, PT thread, CA pivot back cover, built-in magnet.
Quick checklist
This 50mm bore cylinder operates at 30-800 mm/s. At 0.5 MPa it provides 981N push and 881N pull force. At 0.7 MPa the push increases to 1374N, and the maximum theoretical force is 200 kgf at 1.0 MPa.
No, the base MBL uses a fixed rubber bumper to soften the end-of-stroke impact, not an adjustable cushion screw. If your application needs adjustable air cushioning for heavier or faster moves, select the MBLC variant.
