TB Wood's L150118-L150X1-1/8-L-JAW-HUB-1/4-D103 L-Jaw Hub

TB Woods L150118 L-Jaw Hub is an industrial jaw coupling hub designed to transmit torque through a flexible connection while accommodating shaft misalignment in rotating equipment. Featuring a 1-1/8 in bore and a 1/4 in keyway, this L-Jaw hub fits into mechanical drive systems and is commonly used with pumps, conveyors, compressors, industrial motors, and other machinery where reliable torque transfer is required. The part is identified by Part Number L150118 and Model Reference L150X1-1/8, with a D103 marking, and is classified as an L-Jaw Coupling Hub for shaft coupling and torque transmission. Its industrial-grade construction supports installation in manufacturing and utility environments for rotational power transmission and alignment maintenance. Typical applications include motor-driven drives, pump assemblies, and conveyor or compressor systems in demanding settings where shaft alignment stability and shock absorption matter. Common replacements include Lovejoy L-Jaw Coupling Hub, Browning Jaw Coupling Hub, and Martin Jaw Coupling Component.
