Allen-Bradley 18L-18T-1/2-B-BLK Timing Pulley

The Allen-Bradley 18L-18T-1/2-B-BLK Timing Pulley (Part Number 18L) is a shaft-mounted, keyed-bore 18-tooth synchronous belt pulley designed for 1/2 in. wide timing belts, with a timing-belt compatible tooth profile for precise power transmission and shaft synchronization. It supports aluminum or steel construction depending on the application, uses an application-dependent bore size, and is intended for industrial automation and manufacturing equipment. Drive Type is Timing Belt Drive and Mounting Style is Shaft Mounted, with a 1/2 in. belt width and a keyed bore for secure attachment. Typical applications include conveyors, packaging lines, CNC equipment, robotics, and automated assembly systems where synchronized motion and repeatable positioning are critical. System integrators and maintenance teams rely on this pulley for replacements and retrofits; common replacements include Martin 18L050, Browning 18L050, and Gates PowerGrip 18L050.
